FLNG needs offshore know-how

More and more developers are considering floating liquefied natural gas (FLNG) as a strong option for monetizing gas resources. The sustained work over the last five years within the sector has enabled FLNG to mature and be better defined.

Key considerations must be correctly assessed to ensure the success of an FLNG project. These considerations are unique to FLNG, so addressing the project with an LNG mindset will not necessarily result in the correct decisions being made.

One of the most crucial decisions is to select the right FLNG specialists at an early stage. Very few companies know FLNG and have sufficient offshore experience. As an FLNG and offshore specialist, KANFA Aragon has the expertise and experience for successful, simplified and fast execution (Fig. 1).

When considering an FLNG development, whether offshore or onshore, there are several key areas to consider, as discussed below.

Liquefaction technology selection

The key question is whether to select an adjusted onshore liquefaction technology that is unproven offshore, or a technology developed specifically for offshore that already has been proven. As the offshore oil and gas sector has shown, just because something works onshore does not mean that it is suitable for offshore use.

Typically, onshore technologies that are proposed for use offshore utilize flammable, multi-phase refrigerant processes that require very large amounts of space and equipment. Use of such hazardous liquid refrigerants are not ideal for offshore due to performance-impacting vessel motions, limitations on available space offshore, complexity of operation, manpower requirements, and the increased safety demands that operating offshore require.

The optimal choice for FLNG developments is to utilize a nitrogen (N2) cycle. N2 cycles offer a simple, single-phase process using a nonhazardous refrigerant and are an established offshore technology, as they have already been applied as reliquefaction systems on LNG carriers. For those who understand the offshore world, it is the best option for FLNG. This is why KANFA Aragon developed the patented Optimized Dual Nitrogen Expander Cycle, using N2 specifically for offshore liquefaction.

The main argument for hydrocarbon mixed-refrigerant cycles is generated by the traditional onshore LNG focus on efficiency in terms of kW/kg of produced LNG. Mixed-refrigerant cycles are more efficient than N2 cycles. However, for FLNG, developers must look at overall plant efficiency.

Often, plants based on mixed-refrigerant technology are not much more efficient than plants using N2 cycles. Complex hydrocarbon-based technologies usually apply a one-train configuration, and they often use steam turbines with low thermal efficiencies as drivers. For N2 cycles, aeroderivative gas turbines with high efficiencies are applied as drivers, resulting in overall high plant efficiency.

It is important to guarantee reliable production offshore. As such, simplicity always has an advantage over enhanced efficiency in an offshore environment.

Proven equipment

It is also important that equipment is suitable and proven offshore. This is another strength for N2 cycles, as it is generally possible to use equipment that already has references from operating offshore. This further reduces risk and enhances stable production. By using established offshore equipment, it also presents a range of possible suppliers, improving price competition and reducing dependency on single sourcing (Fig. 2).

In an offshore environment, the inherent safety level required as part of the plant and process design is much more stringent than in an onshore environment. Large plants that require bulky equipment in confined spaces—together with high numbers of people and significant storage inventories of hazardous and flammable liquids—present a combination that is not ideal for an offshore environment. However, nonhazardous, simple-to-operate processes using proven offshore equipment present a much simpler and safer method of producing LNG offshore.

Technology provider

For FLNG, it is crucial to select a technology provider with a proven track record offshore. Hiring experienced staff with high expertise in both gas processes and offshore project execution is critical to successful FLNG development.

KANFA Aragon’s most high-profile development to date is for SHI and FLEX LNG. It started with conceptual and generic FEED work; recently, field-specific FEED work was completed for the Elk-Antelope Field in Papua New Guinea. For the field-specific FEED, KANFA Aragon established a joint venture with Worley-Parsons to further strengthen engineering capability. The project is currently awaiting a final investment decision.

With a large amount of development work and FEED done on behalf of SHI and FLEX LNG, KANFA Aragon possesses experience and capability in FLNG (Fig. 3).

Flexible options

As a technology provider and an EPC company, KANFA Aragon can provide flexible execution options. Whether there is interest only in licensing the liquefaction technology, or preference for a full EPC arrangement (including joint ventures with other EPC companies and/or shipyards), KANFA Aragon is able to meet what is best for development. A proven track record in FPSO topside deliveries, together with experience and expertise in FLNG, means that KANFA Aragon can offer developed, verified solutions alongside optimized project execution.

Now that FLNG is maturing and becoming of greater interest, it is more important than ever to ensure that proper considerations are taken and that the right decisions are made. Visit www.kanfagroup.com or contact Tom.Haylock@kanfagroup.com for more information.

Small-scale GTL to enhance refinery operation

A modular, small-scale gas-to-liquids (GTL) plant based on the use of microchannel Fischer-Tropsch (FT) reactors will offer an economical option to expand refinery capacity and make it possible to derive value from smaller accumulations of unconventional gas that would otherwise be left underground. This includes shale gas, tight gas, coalbed methane, and stranded gas.

The GTL plant was developed by Velocys Inc., the US-based subsidiary of Oxford Catalysts Group, and is now under construction at the Ventech fabrication facility in Pasadena, Texas. In contrast to large-scale GTL plants, such as Sasol’s Oryx and Shell’s Pearl plants (both located in Qatar), which are designed to produce over 30,000 barrels per day (bpd) of GTL product, this new, smaller-scale GTL plant has a nominal capacity of 1,000 bpd to 1,500 bpd.

The modular GTL plant, which will be composed of standard-sized, 13.5 ft × 12 ft × 40 ft (4.1 m × 3.65 m × 12 m) modules, takes advantage of two technology breakthroughs—modularization and microchannel technology.

Modularization is a construction method that involves designing refineries and gas processing facilities as a series of modular process and utility units, that are fabricated in a controlled shop environment, and then shipped and connected together on the project site.

Microchannel technology is a developing field of chemical processing that intensifies chemical reactions by reducing the dimensions of the reactor systems. This enables reactions to occur at rates 10 to 1,000 times faster than those in conventional systems, and makes it possible to use more active FT catalysts (Fig. 4).


  Fig. 4. Velocys Inc.’s
  microchannel FT reactor enables
  faster reaction rates and the use
  of more active FT catalysts. 

The Velocys reactors take advantage of a highly active FT catalyst developed by Oxford Catalysts to accelerate FT reactions by a factor of 10 to 15 times the speed of conventional reactors. Individual Velocys microchannel FT reactors are designed to produce 125 bpd to 200 bpd of FT product, and desired plant capacity is reached by linking together multiple reactors to scale production to match the available resource. Plants of this type can also be used as a flexible and economical way to expand capacity at existing petroleum refineries when an economical gas supply is available.

The first customer for this new plant design is Calumet Specialty Products Partners LP, an independent producer of specialty hydrocarbon products in North America. The Calumet plant will incorporate autothermal reforming (ATR) reactors from Haldor Topsøe to produce the syngas feedstock for the Velocys microchannel FT reactors (Fig. 5).

Calumet plans to use the modular GTL plant, which will have a nominal capacity of 1,000 bpd, in the expansion of its specialty products facility in Karns City, Pennsylvania. Fabrication is expected to begin during the first half of 2013. Velocys anticipates that this first modular GTL plant, which is due to come onstream during the second half of 2014, will be the first of many.

Catalyst reduces burner gas use

Catacel’s Stackable Structural Reactor (SSR) metal foil-structured catalyst for steam methane reforming (SMR) has resulted in a 30% decrease in natural gas consumption by a reformer burner since May 2012 at the CPIngredientes hydrogen plant in Guadalajara, Mexico. The lower gas consumption also led to a corresponding increase in plant efficiency.

The reformer configuration at the plant consists of reformer tubes of varying ages, several of which had been recharged with ceramic pellet catalyst as recently as January 2012. After thorough study and analysis, plant management decided to replace the ceramic catalyst media in all reformer tubes with Catacel SSR SMR structured catalysts (Fig. 6). The changeout was completed in May 2012 with minimal downtime.


  Fig. 6. Top view of the
  Catacel SSR catalyst coated
  metal foil unit. 

Catacel’s approach to improving plant efficiency and performance involves coating proprietary, high-performance catalyst onto engineered foil supports (“fans”) designed to deliver superior heat transfer at the same or lower pressure drop than traditional ceramic pellet catalysts. The SSR catalyst’s increased heat transfer coefficient enables the operator to reduce furnace temperatures, with consequent overall energy savings and extended tube and furnace life.

Catalyst media have significant effects on the furnace and tube temperatures needed to achieve the required reaction temperature. Ceramic media typically operates with a 90°C to 100°C temperature differential between the media and the tube. SSR catalyst media, with significantly better heat transfer capability, decreases that differential by 35°C or more. This allows the tubes to operate cooler, extending tube life.

In addition, the SSR fans are engineered to provide a reactive surface area that is about 2.5 times greater than that of typical ceramic media. The higher surface area serves to ensure that more active ingredient is available to the reaction, resulting in longer catalyst life.

Installation of the SSR catalyst was accomplished in 3-ft-long sections of fans delivered to the plant site and inserted into the reformer tubes. Once inserted in place, each section of SSR was expanded to make the individual SSR fans conform to the specific internal geometry of each tube. This installation required 72 sections comprising a total of nearly 2,000 SSR fans installed over a two-day period.

Initial reporting at 100% plant rate with the SSR catalyst indicated a 13.5% reduction in natural gas consumption by the reformer burners over the nominal values of previous months and years of operation. However, readings taken in the following months and at various plant rates demonstrate burner fuel reductions of up to 30%, reduction of reformer temperature, and improvement to overall plant efficiency. Based on current gas pricing in Mexico, return on investment for the entire SSR catalyst charge based only on fuel savings is 2.1 years or less.

In addition to providing ongoing gas fuel savings, the SSR catalyst system does not fracture, clump together, create space voids, or increase tube pressure drop over time, as is typical for ceramic pellets. In summary, SSR technology is expected to allow the catalyst to extend the life of reformer tubes and remain active over the extended tube life.

Piping product reduces gas distribution costs

Evonik’s Polyamide 12 (PA12) VESTAMID NRG is being used by utility companies to install pipes at half the time and price of a steel piping system, thereby revolutionizing the natural gas distribution industry.

The high-performance, lightweight thermoplastic polyamide is a more cost-effective alternative to steel piping and was recently used to tap five additional service lines into a natural gas main in Ulm, Montana.

The product allowed Energy West, a Montana-based gas utility and energy supplier, to complete a piping system to provide gas to homeowners previously using propane, a more expensive energy source. Energy West crews were able to extend the service lines and cut away samples from the previously installed VESTAMID NRG pipeline by using conventional squeeze-off tools to facilitate the removal.

The new piping system operates at 150 psig and can facilitate up to 250 psig. Energy West said annual energy costs for homeowners will be reduced by around 40% when switching to natural gas from propane.

Gas meter excels in low-pressure environments

Primary Flow Signal (PFS) recently announced the availability of its Digester and Bio-Gas (HVT-DG) flowmetering system for high energy recovery in low-pressure digester gas applications.

The HVT-DG is a customizable, insertable venturi meter engineered for each customer’s specific requirements for accurate and reliable measurement in low-pressure, dirty and wet gas situations.

Biogas, or gas that originates from biogenic material, most commonly occurs during sewage or municipal waste processes, and it is typically composed of methane, carbon dioxide or hydrogen sulfide. These viscous materials, which can flow at low or irregular pressures, need to be precisely monitored to ensure that they are disposed of correctly, as leakage could lead to damage or explosions.

The HVT-DG maintains accuracy of +/− 0.25% of actual reading or better, based on hydraulic calibration; it can handle temperatures up to 120°F (49°C); and it features a manual vent cleaner that allows for the removal of particles from the meter, offering a simple solution to ensure that debris does not impact flow measurement.

The sensALIGN intelligence automatically considers the effects of ambient vibration, acceleration of rotation, backlash, speed of rotation, and other factors in determining the quality factor (QF) of alignment readings in harsh field conditions. This makes the system ideal for long-term stand-alone monitoring of machine positional change, as well as routine shaft alignment.

An improved, user-friendly interface makes the ROTALIGN Ultra iS platform faster than ever, while still collecting thousands of measurement points with its patented Continuous IntelliSWEEP method.

With the ROTALIGN ULTRA iS platform, alignment results can be achieved in three steps:

  • Enter dimensions
  • Measure
  • View results.

Accurate alignments reduce unwanted maintenance costs, power consumption and vibration levels while increasing equipment availability.

Farris introduces SmartPRV valve

Curtiss-Wright Flow Control Co.’s Farris Engineering business unit recently introduced the Farris SmartPRV, a 2600 series pressure relief valve (PRV) equipped with a Fisher 4320 position monitor (Fig. 8).


  Fig. 8. The Farris
  SmartPRV monitors
  pressure relief valves in real time. 

With the new technology, PRVs can be monitored in real time, providing immediate feedback during an overpressure event. Areas of the plant that had been difficult or impossible to track using traditional wired products are now effectively monitored. The SmartPRV also extends the range of field applications with Emerson’s SmartWireless solutions network, including critical assets.

Prior to SmartPRV, monitoring of PRVs and the amount of product being released was a daunting task due to the limitations of traditional monitoring technologies, including environmental monitoring of the plant site and simple physical observation of PRVs and flare volume. In both instances, plants have been unable to track product losses.

SmartPRV helps identify production and profitability losses, reduce emissions fines and associated administrative costs, and improve plant safety and environmental performance.

Coating combats sub-insulation corrosion

Sherwin-Williams’ Heat-Flex Hi-Temp 1200 coating is an immersion-grade, single-component, inert, multipolymeric matrix coating that outperforms alternatives in aggressive, multi-cycle laboratory testing. Rigorous protocols based on ASTM International standards documented better corrosion and abrasion resistance, increased flexibility and harder film.

“Our testing was based on accelerated and real-world scenarios involving typical corrosion-under-insulation (CUI) mechanisms,” explained Bruce Toews, global market director for oil and gas at Sherwin-Williams Protective and Marine Coatings.

“In addition to improved corrosion resistance, Heat-Flex Hi-Temp 1200 delivered enhanced durability in transit from shop to job site, and faster shop throughput. Those attributes translate into reduced total cost of ownership and extended service life for high-heat applications and equipment under insulation,” Toews said.

CUI is one of the costliest problems facing the hydrocarbon processing environment today. Major equipment outages, whether for periodic inspection and maintenance or due to a catastrophic failure, account for more operational disruptions than any other cause.

NACE International standard SP0198-2010, “The Control of Corrosion Under Thermal Insulation and Fireproofing Materials—A Systems Approach,” recognizes the increases that have occurred in the temperatures of hydrocarbon processing operations over the past decade—changes that demand the highest-performing products for these applications.

The standard holds that immersion-grade systems are a suitable defense against infiltration by outside moisture or from the process environment itself through seams, gaps or other discontinuities in steel under insulation. Insulated steel capable of trapping water is considered to be under immersion at 210°F (99°C) or higher.

The Heat-Flex Hi-Temp 1200 coating combines ease of application, ambient cure, surface tolerance and ultraviolet (UV) resistance in one formulation for application under calcium silicate and mineral wool insulation systems, and it is recommended for use in wet/dry cyclic service at operating surface temperatures of cryogenic to 1,200°F (649°C), with application temperatures from ambient to 500°F (260°C).

During the testing, the coated panels reportedly outperformed those of competitors, with no adhesion loss or blistering after 80 cycles of the boiling water test when applied at ambient temperatures. This test measures a coating’s performance on a steel panel subjected to thermal shock in a simulated immersion scenario. Accepted as the gold standard for accelerated testing of heat-resistant coatings, this test method measures a coating’s performance on a steel panel subjected to thermal shock in a simulated immersion scenario.

The Heat-Flex Hi-Temp 1200 coating endured a second rigorous CUI testing protocol to gauge the coating’s performance in real-world scenarios involving typical CUI mechanisms, as recognized in NACE SP0198-2010.

Coatings formulated for immersion service are ideal for CUI because the contaminants that pass through the insulation along with the water create an aggressive operating environment. Insulation systems generally vary in their water retention, permeability and wetability characteristics; infiltration can occur due to breaks in the waterproofing, inadequate system design, incorrect installation, poor maintenance practices, or a combination of the above.

Once wet, the insulation system’s weather barriers and sealants trap the water inside, keeping the insulation moist. Next to the equipment surface, the insulation forms an annular space or crevice that retains the water and other corrosive media.

Furnace camera improves industrial efficiency

An application report from FLIR Systems details how the Bayernoil refinery complex near Ingolstadt, Germany has used a FLIR infrared furnace camera to monitor its hydroreformers, enabling them to keep the installations up and running efficiently.

Stable, high temperatures and efficient combustion in refinery furnaces, heaters and boilers are mandatory for continuous output of high-quality oil derivatives. The high-temperature hydroreformer installations at Bayernoil run continuously and at 100% capacity to satisfy high demand for petroleum products. The heavy demands on the hydroreformers make condition monitoring and preventive maintenance of furnaces and heat supply extremely important.

Engineers regularly inspect furnaces at Bayernoil’s three sites, using FLIR GF309 furnace cameras. Calibrated for measurements of up to 1,500°C, the GF309 camera provides temperature readings across entire high-temperature surface areas, enabling faster inspection in critical or potentially hazardous environments. The camera’s protective shield is designed not only to reflect the heat away from the camera and its user, but also to entirely cover the area of a furnace inspection window.

The information gathered by the furnace camera has helped Bayernoil to determine when furnace temperature sensors need to be exchanged. The data also indicate if the temperature of piping remains within safe limits, provide information on whether or not productivity can be raised, and assess the condition of the furnace burners to determine if they need to be adjusted or cleaned.

Using the FLIR Reporter software suite on the GF309 furnace camera, Bayernoil engineers are able to gather and analyze their findings and share them with process safety, production and maintenance specialists at the plants, enabling them to assess and optimize production.

Bayernoil has found that the FLIR GF309 furnace camera has given the company key information on the thermal load of its furnace and piping installations, enabling production optimization and improvement in operational safety. Bayernoil expects the infrared camera to be amortized within two years.

Invensys introduces new quality-management software

Invensys Operations Management has released an updated version of its Wonderware MES software. The newest version expands existing operations and performance management functionality by adding quality management for sample data collection, statistical process control and quality results monitoring, helping to improve operational efficiency, regulatory compliance and product safety.

Wonderware MES 2012 software reduces the cost of quality management while improving regulatory and product safety compliance by capturing complete product, equipment and process-related quality data for both automated and manual operations. The software monitors quality data in near real time, allowing plant operators to respond faster to non-conformance conditions, quality trends and deviations, as well as to take corrective actions that minimize variations and bring quality closer to specifications.

The software complements existing enterprise quality-management systems with sample plan execution automation, higher accuracy in shop-floor quality sample data, integrated statistical process control (SPC), and enhanced work order and operational execution context.

The new features of Wonderware MES 2012 software build out the quality-management capabilities of the original version. The software now enforces manual and automatic data collection, integrates structured sampling plans, and includes rigorous SPC.

The updated software also allows sampling plans to be dynamically generated, according to current work order status for products, equipment and operations. Execution of the sample plans can be performed according to system quality specifications, and the samples themselves can be automated from equipment, control systems or instrumentation. SPC trending and charting are available for near real-time quality monitoring, and they include notifications of violations of control and specification limits.

Flowmeter achieves CE marking under PED

To support McCrometer’s European customers, the Wafer-Cone flowmeter (Fig. 9) now meets the requirements of the European Community’s Pressure Equipment Directive (PED) 97/23/EC and is eligible for use throughout the region.


  Fig. 9. The Wafer-Cone
  flowmeter now comes with
  CE marking. 

CE marking for all service categories under PED 97/23/EC means that McCrometer’s European customers have third-party assurance that the Wafer-Cone flowmeter is safe for use in pressurized environments found in industrial processes and plants. The flowmeter meets essential safety requirements covering design, manufacture and testing. It also satisfies appropriate conformity assessment procedures and carries the CE marking and other information.

The Wafer-Cone flowmeter is ideal for liquid, gas or steam service in line sizes from 1 in. to 6 in. The meter’s flangeless design makes installation easy, while the interchangeable cone offers flexibility to accommodate changing flow conditions without recalibration. When flow conditions change over time, the cone can be removed and replaced with a cone at a different beta ratio, eliminating the need to buy a new meter.

Space-saving and field-proven, the flowmeter can be installed virtually anywhere in a piping system or easily retrofitted into an existing piping layout. No moving parts, virtually no maintenance and an economical cost make it ideal for applications such as wellheads, gas, CO2 and water injection, gas lift, compressor anti-surge, fuel gas, separator discharge, biogas reactors, cooling systems, plant HVAC, process gas lines and more.

The Wafer-Cone flowmeter’s unique differential pressure-sensing technology with built-in flow conditioning greatly reduces the required straight pipe run for installation as compared with technologies such as orifice plates and venturi meters. The Wafer-Cone flowmeter is highly accurate and requires a straight run of only one to three pipe diameters upstream, and zero to one pipe diameters downstream, to ensure measurement reliability.

The flowmeter’s design features a centrally located cone inside a tube, which interacts with the fluid flow and reshapes the velocity profile to create a lower-pressure region immediately downstream. The pressure difference exhibited between the static line pressure and the low pressure created downstream of the cone can be measured via two pressure-sensing taps. One tap is placed slightly upstream of the cone, and the other is located downstream of the cone. The pressure difference can then be incorporated into a derivation of the Bernoulli equation to determine the fluid flowrate.
