High electrical power and fuel costs have made aqua-ammonia absorption systems attractive for many process refrigeration requirements. The economics are especially attractive if waste heat or a high-temperature process stream is available. The chemical and petroleum industries have used waste steam, process vapor streams, hot oil, and stack gases to produce evaporator temperatures from +50/sup 0/F to -50/sup 0/F. Exhaust gas from gas turbines is an excellent source of heat. Because of high exhaust gas temperatures, extremely low refrigeration temperatures can be achieved. Many chemical industry processes require heat extraction at high and low (refrigeration) temperature levels in two different areas simultaneously. If the extraction requirements are within the absorption limits, an absorption system can save many dollars of operating cost by reducing the energy requirements.
