Preventing salt fouling in FCC main fractionators

David O Martin, Nalco/Exxon Energy Chemicals

Richard O Allen, Texaco Ltd

2001 / Q2

Results of using sale dispersant additives on a badly fouled FCC unit has shown that the method allows refiners to avoid more costly methods of naphtha fractionation and, potentially, water washing of the main fractionator.

Steady state simulator to monitor treater performance

Michael C Hu and Robert T Powell, KBC Advanced Technologies

Naoki Yomoji and Danichiro Ohshima, Kashima Oil Company

2001 / Q2

A description of a procedure used successfully at a Japanese refinery in which a steady state hydrotreater model was used to monitor the effects of feed quality, so that changes in key process factors could be matched against catalyst age.

An economic approach to future fuel specifications

Jorg Reinhard, Veba Oel Verarbeitungs GmbH

Ulrich Balfanz, Aral Forschung FDT

2001 / Q2

In anticipation of the extra burden forthcoming fuel specifications will impose on the industry, a joing venture in Germany has gone ahead with a project to convert a surplus heating oil based stream to high-value petrochemical feedstock.

Treating options to meet clean fuel challenges

Rik B Miller, Aristides Macris and Arthur R Gentry, Kellogg Brown & Root Inc

2001 / Q2

The multiple challenges of meeting fuel specifications and upgrading low value streams, such as LCO and heavy naphtha, call for a comprehensive understanding of various hydroprocessing options.  This article discusses some of them.

CO2 management - a refiner's perspective

Simon C Clarke, Foster Wheeler Energy Ltd

2001 / Q2

A review of the general issues of carbon dioxide emission that concern the refiner - and an indication of how some smart targeting and decision-making, with enhanced operation, can establish the business in the global marketplace.

Removal of silica particles from flue gases

G Gentilini, M Giovinazzi, B Manduca, G Iaquaniello, Kinetics Technology International SpA (KTI)

2001 / Q2

Venturi scrubbers combined with wet electrostatic precipitators have been found to achieve more than 99 per cent removal of fine particle pollution.  The authors look at the efficiency of flue gas treatment in the removal of very small particles.

More

Intelligent hydrogen network management

L McGregor and G Colantuoni, Gensym

D Lupica and M Tarantino, AgipPetroli

2001 / Q2

Real-time intelligent systems can make significant improvements to the H2 utilisation efficiency of petroleum refining operations.  This article examines the application of a hydrogen network management system at a refinery in Italy.

More

Fractionator and gas plant revamp for best returns

Krish Nangia, David Schulte, Ed J Smet, Fluor Daniel

Bernard Demulder, TotalFinaElf

2001 / Q2

A review of a combination of options available for switching modes of operation for the FCC main fractionator and the gas plant, bringing an improvement in selectivity, together with the ability to operate at a higher throughput.

More

Reboilers behind distillation tower problems

Edward L Hartman and Daryl W Hanson, Koch-Glitsch Inc

2001 / Q2

A review of common reboiler designs, with a discussion of case studies of reboiler problems that caused towers to fail to meet expectations.  The aim in each case was to undertake simple modifications to reboiler circuits without costly revamps.

More

Avoiding unscheduled shutdowns

Gary L Martin and Tony Barletta, Process Consulting Services Inc

2001 / Q2

Case studies have demonstrated that correct heater design and consequent performance will determine crude unit run length.  This article reviews two case histories that highlight some of the problems that result in rapid coking.

More

Instrumentation: the key to revamp benefits

Andrew W Sloley, The Distillation Group Inc

2001 / Q2

The author presents some examples from recent troubleshooting experiences at plants with ineffective instrumentation, all of which caused major losses before they were found and fixed.

More

A reformer model for a petrochemicals complex

Hyun Chul Kim and Hae Sup Yoon, Samsung General Chemicals

Lee Turpin, Ajay Lakshmanan, Nam Soo Park, Aspen Technology

2001 / Q2

A recently built petrochemical complex has been working on a programme to predict the yield patterns for a variety of feeds and operations, using case studies to determine how actual performance compares with the plant's potential.
