FCC propylene production

Ketih A Couch, James P Glavin, Dave A Wegerer and Jibreel A Qafisheh, UOP LLC

2007 / Q3

Factors influencing the selection of propylene yield design points and a comparative study of an absorption-based gas concentration unit relative to cold-box recovery design show how refiners can leverage existing assets to close the market gap for propylene production.

The FCC unit as a propylene source

Charles Radclife, Intercat Inc

2007 / Q3

The FCCU is an important source of propylene production.  Hardware and catalyst design changes can increase the propylene yield, but ZSM-5 and other additives are essential to optimise and retain the flexibility to respond to today's and tomorrow's challenges.

Crude overhead system design considerations

Tony Barletta and Steve White, Process Consulting Services

2007 / Q3

Proper crude unit overhead system design is important when building a new unit or revamping an existing one to process different crudes.  Overhead condenser designs should meet the specific processing objectives, such as distillate yield, run length and energy recovery.

Evaluation of sulphur-reducing technologies

 Lauren Blanchard, Grace Davison

Craig Borchert and Min Pu, Valero Energy Corporation

2007 / Q3

Case study where the impact of a FCC feed hydrotreater outage was minimised by running carefully selected feeds combined with sulphur-reducing technology appropriate for the type of sulphur species expected to be processed during the outage.

Selective hydrogenation of hydrocarbons

Amarjit Bakshi, Refining Hydrocarbon Technologies LLC

2007 / Q3

Selective hydrogenation and isomerisation of diolefins using fixed-bed conventional technology in a two-phase reactor configuration can help refiners to meet sulphur and aromatics limits for fuels such as gasoline, kerosene and diesel.

Expanding FCCU wet gas compressor capacity

Tek Sutikno, Fluor Corporation

2007 / Q3

Parametric correlations can predit WGC performance curves at different speeds and molecular weights.  However, performance curves in a range of speeds and suction pressures must first be made available.

More

Dynamic simulation of a FCC unit

Yiannis Bessiris and Vassilis Harismiadis, Hyperion Systems Engineering Ltd

2007 / Q3

Increasingly complex FCC operations, such as predicting FCCU operation after switching from a conventional feed to a hydrotreated one, can benefit from simulation applications that improve the unit's real-time control system.

Upgrade of a tail-end acetylene converter

Edgar Mohundro, BASF Fina Petrochemicals

Sam Valleru, Scott Miller and Juergen Fuchs, BASF Corporation

Dimitri Mertens de Wilmars and Bruno Leaustic, Total Petrochemicals

2007 / Q3

An acetylene converter's poor performance was improved through the implementation of a succession of changes.  Over a period involving several strategies, all acetylene off-specification incidents and flaring events were eventually eliminated.
