Process Integration Methodology for Natural Gas-Fueled Heat Pumps and Cogeneration Systems. Final Report March 1987-October 1988

摘要

The objective of the project was to develop a process integration methodology for analyzing industrial processes, identifying those that will benefit from natural gas-fueled heat pumps and cogeneration system as well as novel, process-specific opportunities for further equipment improvements, including performance targets. The development included the writing of software to assist in implementing the methodology and application of the procedures in studies using both literature data and plant operating data. These highlighted potential applications for gas-fueled heat pumps in ethylene processes and liquor distilling plants, and slightly less attractive opportunities in a number of other plants. Many of the processes studied showed excellent potentials for cogeneration applications. A particularly attractive novel cogeneration application was identified for a wet corn mill, in which the exhaust for a gas turbine can be used to provide exhaust heat in flash driers that handle non-food grade products.
