Consider trigeneration techniques for process plants. S. Dharmadhikari. Hydrocarbon Processing, July 1997, 76(7), 91--100.

The use of trigeneration techniques for producing heat, power, and refrigeration is reviewed and typical designs of trigeneration units are described and illustrated. The main features are drivers, waste heat recovery, refrigeration equipment, and compressors. A thermodynamic analysis shows the overall efficiency of a co-generation cycle. Capacity size limits are discussed and different trigeneration configurations are compared. Trigeneration using gas engines and using gas turbines is described. A techno-economic analysis of seven different process schemes is tabulated. Design changes to improve plant economics include boosting gas turbine power during hot weather, and using variable speed compressor chillers. 4 refs.
