A study was carried out on the optimum placement of heat pumps in industrial processes. Ten processes from a variety of industrial sectors were selected from a total of 26 candidates and were analyzed for optimal heat pump placement using the methods of pinch technology. This procedure provides a systematic and thermodynamically consistent means of evaluating heat pump applications and the savings they yield in terms of overall process energy usage. Pinch analysis has been used to identify and quantify opportunities for energy savings by heat integration, heat and power integration, and distillation system modifications as well as heat pumping. Numerous potential applications were identified for current heat pump systems and considerable scope was also found for possible advanced heat pump technologies. Considerable additional benefit could be derived from advanced heat pumps capable of economically acceptable performance with temperature lifts up to about 150/sup 0/F at delivery temperatures of around 350/sup 0/F. The scope for replication of the heat pumping options identified in this study was estimated. This evaluation indicated that the total potential for energy savings nationally in the ten processes studied is about 32.9 x 10/sup 12/ Btu/year or about 10% of the current energy usage.
