Sample heat transfer fluids to offset carbon effects on thermal plant efficiency

Wright, C., Global Heat Transfer

The long-term viability of a plant depends on maintaining continuous output and reducing production costs.

Optimize isomerization reactor temperatures and component RON

N. Toraman, K. Kahraman, TÜPRAŞ-Turkish Petroleum Refineries Corp.; P. Billings, O. Sabitov, Honeywell UOP

Isomerate is useful because it is paraffinic and contains no benzene, aromatics or sulfur. This pentane and hexane fraction of crude oil is known as light naphtha. The main objective of reactions is to increase the research octane number (RON) of the components. Decreasing fuel consumption without changing the product RON of isomerization units is discussed here.

Use computational fluid dynamic analysis to revamp fired heaters

Garg, A., Chilka, A., Furnace Improvements Services Inc.

A refinery process fired heater system consists of multiple sub-units, of which the fired heater is the most critical, as it impacts the overall efficiency of the system.

Calculate thermal efficiency to optimize fired heater operation

Ibrahim, M. E., Shirpurkar, V. D., Saudi International Petrochemical Co.

In a Saudi International Petrochemical Co. petrochemical plant, fired heaters are designed to supply heat duty at 7 MW and are one of the major consumers of energy.

Minimize unplanned shutdowns of fired heater operations

Baukal, C., John Zink Co. LLC; Newnham, R., OnQuest Canada ULC; Johnson, B., John Zink Hamworthy Combustion

There are many potential “rules,” or guidelines, for the safe operation of process heaters.

Major accident and failure of stationary equipment in the RFCCU

Seok, W., Lee, S., SK Energy

The four case studies cover component failures and multiple types of leakage: valve packing, expansion joint and corrosion.

Control fouling on preheat trains with a two-stage approach

Fouling in heat exchanger preheat trains is a well-known problem in the refining industry.

Alfa Laval to supply heat exchangers for Korean petrochemicals complex

The order comprises the delivery of Packinox heat exchangers which will recover energy in the production of mixed xylenes, ingredients in the manufacturing of synthetic nylons and PET bottles.

Mitigate vibration issues in shell-and-tube heat exchangers

Dole, R., Sridhar, S., Vivekanand, S., L&T-Chiyoda Ltd.

Heat exchanger tubes tend to vibrate when influenced by crossflow velocities.
