Process Optimization

Editorial Comment

Nichols, Lee, Hydrocarbon Processing Staff

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

Nichols, Lee, Hydrocarbon Processing Staff

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.
