Ensuring safety in dynamic chemical manufacturing environments

Knecht, S., ITT Goulds Pumps

As with all industries, chemical manufacturing is evolving in response to technical innovations, new customer requirements and increased global competition.

Improved measurement of water content in natural gas

Garza, A., Miller, S., Endress+Hauser

Consumers likely imagine natural gas as a stream of pure methane. Those who are closer to the energy industry know that methane is the major component, but there can easily be dozens of other substances making up a sizeable portion of the total volume.

Editorial Comment: Maintenance and reliability—A cornerstone of safe and efficient plant operation

Nichols, Lee, Hydrocarbon Processing Staff

Refineries and petrochemical plants are comprised of a series of crucial processes to produce transportation fuels, products and chemicals demanded by the global market. These processes consist of capital-intensive units that must be maintained to provide reliable performance. Failure to adequately maintain these assets can have a detrimental effect to not only operations and profit, but also to worker safety.

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.

Improve the reliability of a CO2 compressor in a urea synthesis/granulation plant

Zardynezhad, S., CNRL-Canada

The carbon dioxide compressor is one of the key major equipment in a urea production plant that produces fertilizers.

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.

Down with downtime: Repair complex petrochemical components with selective electroplating

Arana, T., SIFCO ASC

The volatile impact of the coronavirus pandemic hit at the same time the petrochemical industry was entering a downcycle.

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.

Editorial Comment: The tools advancing the HPI into the digital age

Nichols, Lee, Hydrocarbon Processing Staff

The HPI has been going through a digital transformation, increasingly adopting digital technologies to improve existing processes and structures to improve performance.

Improving asset utilization by closing the corrosion window

Zurlo, J. A., SUEZ Water Technologies & Solutions

Driving profitable refinery operations often requires owner-operators to balance production flexibility and product optimization with asset availability and equipment reliability.
