Editorial Comment
Over the past several decades, the hydrocarbon processing industry has invested heavily in new processing units to produce low-sulfur and ultra-low-sulfur (ULS) transportation fuels.
Industry Perspectives
In the second half of 2021, Hydrocarbon Processing is hosting two events to showcase the leading technologies and people in the refining, petrochemicals and gas processing/LNG industries: The International Refining and Petrochemical Conference (IRPC) and the HP Awards. A “call for abstracts” has opened for both events.
TOTAL refineries improve overhead systems corrosion and salting with amine-neutralizing technology
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.
Determining the indeterminate
Standards such as API, ASME and NFPA are applied widely in the refining industry.
Design considerations when flaring ethylene oxide
The flaring of gases released from normal process vents and safety valve discharges following an overpressure scenario is widely practiced in refineries, petrochemical and chemical plants.
A solution to the IMO 2020 MARPOL Annex VI requirement
On January 1, 2020, a new requirement limiting the sulfur content of marine fuel to a maximum of 0.5 wt% went into effect.
