All Sulphur Plants Are Not Created Equal

Apr 2, 2012
Angela Slavens
All Sulphur Plants are Not Created Equal ABSTRACT Sulphur recovery from natural resources is required to meet environmental regulations on sulphur content in final products, as well as SO x emissions restrictions imposed on processing facilities. While sulphur recovery facilities in oil refineries...

Installing a Charge Gas Compressor Booster

Apr 2, 2012
Giorgio Franceschetti
The Braskem Ethylene Southeast Plant expansion study from 500 MTA to 700 MTA recommended that the charge gas compressor turbine and the 1 st and 2 nd stages should be replaced. Due to a series of technical and logistical constraints, was decided to install a booster compressor upstream the first...

Re-Rating Ethylene Plant Equipment for Optimum Results

Apr 2, 2012
Daniel Renard
Rerating of turbomachinery equipment installed in ethylene plants is a well established method of improving plant operation, whether it is capacity changes, feedstock flexibility, power reduction or combination of all three. By utilizing modern compressor and steam turbine component technology,...

Applying Offline Tools to Reduce On-Site Control Implementation Effort

Apr 2, 2012
Kenneth V. Allsford
Process control engineers are continuously challenged to reduce the effort to commission new advanced regulatory control strategies and/or linear/nonlinear multivariable control applications. Reducing on-site controller identification and tuning and the associated "interference" with process...

Dynamic Simulation of Demethanizer and Chilling Train System

Apr 2, 2012
Shujing Zhang
The chilling train system is an important part of ethylene plant which is usually combined with demethanizer and a series of flash drums to separate hydrogen and methane from cracked gas, and recover the hydrogen and methane as different products through multi-stream heat transfer with refrigerants...

How to Structure a Basic Care Strategy for Rotating Equipment

Apr 2, 2012
Gampa Bhat
Do your operators and management know the real health of your machinery?. Do they depend too much on the alarm notification of the abnormal condition which may be too late to react? Every operation unit needs to have a Basic Care based management system which includes operator walkabouts,...

Tutorial: The Chemistry of Refinery Fouling

Apr 2, 2012
Irv Wiehe
The chemistry of refinery fouling is well enough understood to mitigate nearly all fouling. The key information required are the location of the foulant, elemental analysis of the foulant, and identification of precursors in the oil flowing through the fouled unit. Most organic fouling is caused by...

Mixed Fluid Cascade, Experience and Outlook

Apr 2, 2012
Heinz C. Bauer
The first Base Load LNG plant, which has been built using the Mixed Fluid Cascade (MFC ® ) process, started up in 2007 at a Norwegian location close to the city of Hammerfest. Many first-of-its-kind solutions have been implemented successfully including an all-electric-drive concept, CO 2...

Useful Tips for Optimal Fired Heater Performance

Apr 2, 2012
Nikki Bishop
Advanced Process Control Strategies for Process Fired Heaters Fired Heaters are used extensively throughout refineries for heating, vaporization and thermal cracking of various process fluids. These heaters are essential for refinery operation. The main objectives for fired heater optimization are...
