Comparison of clean diesel production technologies

C K Lee and Steve McGovern, PetroTech Consultants

2002 / Q1

Technology is available for meeting 15ppmw sulphur for road transport diesel, but technologies required to produce ultra low sulphur diesel are not necessarily the same as those for producing diesel with high cetane and low polyaromatics.

Revamping conceptual process design

Tony Barletta and Gary Martin, Process Consulting Services Inc

2002 / Q1

With the desirability of getting the maximum use out of existing equipment when revamps are planned - not least to minimise investment costs - a rigorous approach to CPD is required to avoid scope growth.

Understanding gas treating fundamentals

James L Jenkins and Randy Haws, CCR Technologies Inc

2002 / Q1

While much is being placed on the study of conversion and hydroprocessing units, refiners are finding that primary amine units and associated sulphur plants require study and optimisation to meet the new environmental challenges.

Effect of feed properties on FCC unit performance

Robert J Campagna, Dennis C Kowalczyk, Jack R Wilcox, Refining Process Services Inc

2002 / Q1

Hydrotreating FCC feed is a viable option for refiners wishing to produce ultra low sulphur gasoline and diesel fuels, and the economics are superior to product-treating, say the authors, but they warn of the high capital costs that this entails.
