Integrated solutions for optimised ULSD economics

Ronnie Maddox Tom Kalnes Dave Lindsay UOP LLC

2003 / Q4

An illustration of low cost solutions to ultra low sulphur diesel production, with case studies of integrated hydrocracking revamps – showing up to 70% savings in new units using new reactor internals – and novel separation and coprocessing



More

Characterisation and analysis of resids James G Speight CD&W Inc

 

2003 / Q4

A description of the properties that are required for a detailed evaluation of resids and for comparison between resids and how they play a role in dictating which refinery operations are necessary for processing



More

Trouble-free design of refinery fractionators

Henry Z Kister Fluor Corporation

2003 / Q4

A review of factors most frequently the cause of distillation towers falling short of design objectives. Analysis of case histories provides guidelines for identifying potential troublespots in the most important fractionators



More

Specifications – importance of getting them right Steve White and Scott Fulton Process Consulting Services

 

2003 / Q4

Faulty equipment specifications sometimes carry unforeseen penalties, with loss of performance. But do not blame the original equipment manufacturer, say the authors – it is the process design engineer’s responsibility to meet the objectives
