Circular economy: Getting in the door of opportunity ahead of a vanishing polymer market
Accenture: Bjacek, P.

Significant change is coming to the hydrocarbons industry. Up to 43% of the global conventional polymer production expected by 2040 may disappear due to circular economy (CE) initiatives. In addition, due to the growth in wind turbines and solar panels, and in lightweight composite materials in cars and planes, advanced materials waste is just beginning.

Brazilian developments in the biofuels market

Since the 1970s, Brazil has been a world reference in automotive biofuels, especially bioethanol produced from sugarcane. In 1973, the Organization of the Petroleum Exporting Countries (OPEC) forced a sharp rise in oil prices, triggering a massive slowdown in the country’s economic growth, which had been going through what was dubbed the “economic miracle,” with growth at an average of 12% of GDP. This study gives an overview of the biofuel sector in Brazil, along with the main business challenges and opportunities in this area.

Can ammonia be a future energy storage solution?

Ammonia is well known as a fertilizer. However, it is also a potential carbon-free fuel and an excellent solution for storage of renewable electricity, especially if the syngas needed for producing the ammonia is made by electrolysis.

Treat toxic, malodorous ethylene spent caustic using WAO technology
Siemens Water Solutions: Clark, M.
Sinoec Zhenhai Refining & Chemical Co.: Xia, N.

As China’s largest integrated refinery, Sinopec’s Zhenhai Refining & Chemical Co. (ZRCC) plant can process approximately 23 MM metric tpy of crude oil. The plant produces more than 50 fuel and chemical products, including different grades of gasoline, jet and diesel fuels, asphalt and polypropylene plastics, as well as more than 1 MM metric tpy of ethylene. The latter generates spent caustic, one of the world’s most toxic wastewaters.

Process Optimization

A new liquid-phase isomerization process for xylene loop debottleneck and energy savings
Reliance Industries Ltd.: Mhatre, S.  |  Warke, V.
ExxonMobil Chemical Co.: Choi, A.  |  Molinier, M.  |  Saple, A.

In a typical xylene loop, C<sub>8</sub> aromatics are fractionated out of a heavy reformate C<sub>8</sub>+ aromatics stream and collected in the xylene column overhead. Then, paraxylene (PX) from the C<sub>8</sub> aromatics stream is recovered as product—usually by an adsorption or crystallization process—in the PX recovery section.

Optimization study in hydrocracker unit using simulation model

Hydrocrackers are key refinery units that convert heavy feed components into valuable lighter products. The profitability of these units is directly related to this conversion level. Conversion reactions take place in a nearly pure hydrogen environment, with the help of selective catalysts, under high pressure and high temperature. The products of the unit are separated in the fractionator section. Unconverted oil taken from the fractionator bottoms reveals the conversion performance of the unit.

RAM analysis for refinery process design optimization
Fluor Enterprises, Inc.: Gandhi, S.  |  Kortnicki, H.  |  Nangia, K.

RAM refers to reliability, availability and maintainability analysis. The RAM model uses discrete event simulation (DES) software and provides a quantitative assessment of the performance of an industrial plant. This article discusses the use of RAM analysis on petroleum refinery projects to select an optimum process configuration and associated storage requirements.


FCCU catalyst reformulations: Reducing risk and guaranteeing value with collaboration/testing
Hellenic Petroleum: Kyriakou, S.  |  Plellis, C.  |  Tatsis, V.  |  Damianou, C.  |  Gkanis, D.
W. R. Grace: Burgess, T.  |  González, R.

Hellenic Petroleum S.A.’s Aspropyrgos refinery is located near Athens, Greece. It has a total refining capacity of approximately 7.5 MMtpy and a Nelson complexity index of 9.7. The refinery was built in 1958 and has undergone several upgrades, including the installation of a fluid catalytic cracking unit (FCCU).

Heat Transfer

Case study: Heat exchanger tube rupture and its impact on metal embrittlement
Reliance Industries Ltd.: Dingankar, S.  |  Mahulkar, S.
TechnipFMC: Schutt, M.  |  Mahalingam, S.
Technip India Ltd.: Banerjee, S.

Process engineers strive to recover as much energy as is practically possible from the available process and utility streams within the constraint of the plant. To achieve this goal, traditional—and sometimes non-traditional—methods are utilized. In a steam cracker, light olefins are considered the highest-value products, and utilizing “cold energy,”

Valves, Pumps and Turbomachinery

Reveal the unmonitored risks in your rotating equipment—Part 1
Bently Nevada, a Baker Hughes Business: O’Connor, D.  |  Gutierrez, J.

On December 15, 2002, an anomalous event occurred in a steam turbine of Unit 2 at the South Texas Project Electric Generating Station, a pressurized water reactor (PWR) nuclear reactor near Bay City, Texas. The ensuing investigation concluded that a blade was ejected from a low-pressure stage, and detailed inspections revealed additional cracked blades in several stages.

Process Controls, Instrumentation and Automation

Optimal gas analysis decisions improve ethylene plant operation
Emerson Automation Solutions: Kamphus, M.  |  McMillen, D.

One of the most common and important building blocks in the petrochemical industry is ethylene, constituting a huge and fast-growing worldwide industry. Ethylene is an intermediate chemical used to manufacture many commercial products—approximately 200 MMt will be produced in 2020.


Editorial Comment: Processing a sustainable future
Hydrocarbon Processing Staff: Nichols, Lee

An emerging topic along the entire oil and gas value chain is the move toward <i>sustainability.</i> Each company has a somewhat different definition of what sustainability means to its operations.

Reliability: Things rarely heard at reliability conferences
Hydrocarbon Processing Staff: Bloch, Heinz P.

We can only guess how many reliability conferences we have attended since accepting job offers in the refining or chemical processing industries. In my case, starting in 1965, it is somewhere between 60 and 80. If, in each of these conferences I listened to six presentations, the number of sessions attended is perhaps 400.

Digital: Technologies are advancing industry beyond alarm management
PAS Global: Hollifield, B.

Let’s face it, alarm management is a fully mature body of knowledge. Since the mid-1990s, industry has improved thousands of alarm systems, transforming them from overloaded nuisances to valuable operator tools for abnormal situation detection and response.

Roundtable: The skills gap: How to bridge it and how to close it
Airswift: Marx, J.
Lloyd's Register: Stuart, J.
Energy Jobline: Peet, H.

The skills gap is not a new phenomenon for the oil and gas sector. An aging workforce and increased competition for tomorrow’s technical talent have left the industry nervous about its future. On the heels of the 2019 Global Energy Talent Index (GETI), a panel of experts came together to discuss the sector’s ongoing struggle with the skills gap and what oil and gas/energy companies can do about it.
