Computer-Aided Design Reveals Potential of Gas Turbine Cogeneration in Chemical and Petrochemical Plants
MetadataShow full item record
Gas turbine cogeneration cycles provide a simple and economical solution to the problems created by rising fuel and electricity costs. These cycles can be designed to accommodate a wide range of electrical, steam, and process heating demands. The optimum cycle is typically based on an analysis of the plant's electrical / steam / process heating requirements, an evaluation of the potential for selling to or permit wheeling by utilities of electrical power under PURPA guidelines, and application of pertinent investment decision criteria. The study that identifies the best solution to the problem must contain sufficient detail to support a plan of action by management. This paper addresses how computer-aided design techniques support the effort necessary to fully evaluate several alternative cycle designs in a short time frame. It includes examples for a new power unit as well as for cycles which require modifications to existing process and steam generating equipment in a medium-sized chemical plant.
