Understanding HCN in FCC: Formation, effects and mitigating options

Riva, S., BASF; Challis, S., Chalcat Consulting

In these challenging times, fluidized catalytic cracking units (FCCUs) aim to improve margins by processing poorer- or different-quality feeds, while maintaining good yield performance.

TOTAL refineries improve overhead systems corrosion and salting with amine-neutralizing technology

Brun, L. A., Majorel, C., Thoret-Bauchet, J. P., Total; Pothuaud, A., Cross, C., SUEZ Water Technologies & Solutions

Weak organic amines are commonly used in crude unit overhead systems to prevent acidic corrosion from chlorides and other acidic contaminants via a neutralization reaction.

Leveraging digital technologies to create the smart renewable diesel facility

Harclerode, C., OSIsoft

Many companies are modifying existing crude refineries or building grassroots renewable diesel facilities to produce drop-in, green renewable diesel from a variety of agriculturally derived triglyceride feedstocks.

Reducing acid consumption: Maximizing sulfuric acid alkylation unit profitability

Peterson, J. R., Rana, D., Ewing, R., DuPont Clean Technologies

Alkylation is a process used to produce highly branched isoparaffins from the reaction of lighter olefins and isobutane in the presence of sulfuric acid as a catalyst.

Converting a petroleum diesel refinery for renewable diesel

Chan, E., Burns & McDonnell

As refiners consider renewable, low-carbon alternatives, renewable diesel—refined from agricultural products using petroleum refinery processes—is gaining traction.

Rhodes, Mike, Hydrocarbon Processing Staff

U.S. refinery margins extended their upward trend for the fifth consecutive month, exhibiting the largest upturn relative to other regions.

Fuels and chemicals: Finding the right refinery configuration for a less predictable world

Chaudhuri, S., Singh, R., Bechtel India

The refining industry links the upstream production of crude oil with the end markets for fuel products, as well as for the petrochemical/chemical industry.

Specifying internals in sour water strippers—Part 1

A sour water stripper (SWS) system is a common process in petroleum refineries and other processes where hydrogen sulfide is present.

Benefits of using a master station for actuator supervision and control in metering skids

Loth, S., AUMA

Valve automation in metering skids for the oil and gas industry is a challenging task.

Troubleshoot flooding problems in a crude distillation column

Crude oil is separated into more valuable products, such as naphtha, kerosene, light diesel, heavy diesel and atmospheric residue, in crude distillation units (CDUs).
