Special Focus: Petrochemical Technologies

A novel process for the oxidative dehydrogenation of ethane to produce ethylene and acetic acid
Linde Engineering: Bermejo, R.  |  Dörhöfer, T.  |  Kracker, G.

The authors’ company has developed a commercial chemical process<sup>a</sup> for the oxidative dehydrogenation of ethane (ODH-E). By means of a heterogeneous catalyst, ethane and oxygen are selectively converted into ethylene and acetic acid, which, after separation and purification, are provided in polymer-grade and glacial quality, respectively.

Capture the full value of waste plastic pyrolysis oil through innovations in hydrocarbon analysis
Lummus Technology: Borny, J. F.  |  Chakraborty, S.

Today, the world produces twice as much plastic waste as it did two decades ago, with the majority ending up in landfills, being incinerated or leaking into the environment.

Control primary properties online in polyethylene and polypropylene rectors by using functional correlations
Polyolefins Technology Consultant: Divey, J. D.

Polyolefins products such as high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE) and polypropylene (PP) form approximately 65%–70% of all polymers manufactured globally.

Process Optimization

An innovative process for simultaneously producing high-purity benzene and U.S.-grade gasoline from FCC C6 heartcut
Reliance Industries Ltd.: Garg, M.  |  Patil, R.  |  Sapre, A. V.
CSIR-Indian Institute of Petroleum: Kumar, S.  |  Ghosh, P.

Mobile Source Air Toxics (MSAT) II regulations restrict the average benzene level in gasoline sold in the U.S. to 0.62 vol%. In India and in several other countries, benzene in gasoline is presently restricted to 1 vol%. Fluid catalytic cracking (FCC) gasoline contributes to nearly 10%–20% of the gasoline pool in a typical refinery.

Catalysts

Decarbonize the FCCU through maximizing low-carbon propylene
Cepsa R&D: Pérez, E.  |  Prieto, C.
Cepsa, Gibraltar Refinery: Moreno, J. A.  |  Tenorio, J.  |  Chavarría, A.
W. R. Grace: Bescansa, M  |  González, R.  |  Brandt, S.  |  Franken, J.

As the global energy system continues to be threatened by geopolitical tensions, the refining industry continues to demonstrate an outstanding capacity for adaptation.

Plant Design, Engineering, Construction and Commissioning

Pellet handling system for polyolefin plants: Are you specifying it correctly?
Bechtel Energy: Tiwari, V. K.  |  Guharay, S.

Product pellets produced in polyolefin plants—such as polyethylene (PE) or polypropylene (PP)—require transportation from the unit to the end users that process these pellets to manufacture different end-use plastic products.

Hydrogen

Sustainable H2 production through methane pyrolysis
Saudi Aramco: Al-Qahtani, A.  |  Al-Warthan, F.  |  Khani, A.

The methane (CH<sub>4</sub>) pyrolysis process [also known as CH<sub>4</sub> cracking or turquoise hydrogen (H<sub>2</sub>) production] is a thermal (high-temperature) breakdown of CH<sub>4</sub> into H<sub>2</sub> gas and solid carbon.

LNG

Navigating the complex LNG value chain
Emerson: Awasthi, R.  |  Rendon, M.

Throughout the last two decades, LNG technology improvements have built a global natural gas market. This globalization has led to an increase in demand, but also an increase in instability, as changing global events and the drive towards increased sustainability in energy sources have created market fluctuations from all directions.

Valves, Pumps, Compressors and Turbomachinery

Directly calculate pipe diameters through valves and fittings under a turbulent flow regime
Contributing Author: Garcia, I.
Kuraray America Pasadena: Garcia, A.

Calculating pipe diameters through long, straight pipes is executed in classic fluid flow problems using traditional trial-and-error methods or by complex equations.

Process Controls, Instrumentation and Automation

Flare flow measurement
The NEWTRON Group: Tamboli, D.

Flare gas meters are used in facilities such as oil rigs, refineries and chemical plants to measure the gas flows in flare lines. In many parts of the world, this is a regulatory requirement.

Environment and Safety

An ignition control nightmare—Protecting assets from a lightning strike
Contributing Author: Khan, A. J.

Design engineers put forth their best efforts to forecast all risks for their processing plant and strive to embed optimum controls in design, commissioning, operations and maintenance to prevent these risks during the plant’s lifecycle.

Tanks, Terminals and Storage

Do not overlook the base when insulating hot storage tanks
Owens Corning: Schraeyen, S.  |  Van Loo, J.

Hot storage tanks in petrochemical facilities, terminals and industrial sites globally house valuable and often volatile products, including organic liquids, raw materials, intermediate fuels and byproducts.

Editorial Comment: As petrochemicals demand increases globally, novel processes, systems and technologies continue to evolve
Hydrocarbon Processing Staff: Nichols, Lee

Over the next 25 yr, global petrochemicals demand is forecast to increase exponentially, rising from approximately 450 MMtpy in 2025 to > 500 MMtpy in 2035 and upwards to nearly 600 MMtpy by 2050.

Executive Viewpoint: FCC propylene production, catalysts technologies and new solutions
Hydrocarbon Processing Staff: Nichols, Lee

Welcome to <i>Hydrocarbon Processing’s</i> new Executive Series. In this enhanced video platform, the editors speak with the operators and technology leaders and suppliers that are optimizing the global hydrocarbon processing industry (HPI).

Business Trends: A 2024 and beyond outlook for the GCC chemical industry

The global chemical industry faced a challenging year in 2023. Various factors contributed to sluggish demand growth for chemicals globally, including the European recession, U.S. inflation and a lower-than-expected chemical demand rebound in China. These factors resulted in global chemical market growth of < 1% in 2023, with many producers experiencing lower output.
