Energy losses from the radiant firebox wall of pyrolysis furnaces
Bueno, A., Regueira, V., Braskem S.A.; Leite, L., Federal University of Rio de Janeiro

The steam cracking unit is highly energy demanding, requiring high-severity pyrolysis furnaces to break the carbon-carbon bonds, as well as high pressure for the purification of its products.

CFD simulation in chemical reaction engineering
Aglave, R., Eppinger, T., Siemens PML Software

Reaction engineering is a branch of chemical engineering that deals with the design and optimization of chemical reactors.

Establishing a plastics processing sector in NE India—A short analysis
Phukan, P. K., Brahmaputra Cracker and Polymer Ltd.

The Assam gas cracker project was proposed as a part of the implementation of the Assam Accord, which was signed on August 15, 1985.

Process Engineering

Aqueous chemistry principles applied to refinery processes
Cardoso, R., Phillips 66

In the petroleum refining industry, pH measurement and adjustment are extremely important.

Process Optimization

Speed up the development of new commercial adsorbents—Part 1

In the conventional development approach, a multi-stage process begins in the laboratory, moves to the pilot plant, and ends at the commercial unit, often before any financial benefits are realized.

An optimized approach to choosing solvent for the liquid-liquid extraction process
Gupta, A., Jain, S., Reliance Industries Ltd.

Liquid-liquid extraction (LLE) is a traditional method used for separating a specific component (solute) from the carrier liquid phase.

Enhancing refinery profitability with a novel offgas conversion technology
Aronson, A., Zaziski, D., Siluria Technologies

The refining industry is challenged every day to optimize product slates that comply with market demand, product specifications, environmental regulations and refining-petrochemical integration, all while remaining profitable.

Environment and Safety

Optimize your insulation to reduce costs

Corrosion under insulation (CUI) is a common problem that is shared by the oil and gas (onshore and offshore), refining, petrochemical, power and manufacturing industries.

How pipeline management becomes part of a plant safety strategy
Liston, C., HIMA Americas, Inc.

A typical refinery or chemical plant contains miles of pipelines.

Process Control and Instrumentation

Measuring steam flow to flares
Menezes, M., Emerson Automation Solutions

Refinery flare stacks are designed to combust all manner of unrecoverable hydrocarbon gases and vapors to avoid putting them into the atmosphere in their original form.
