Abstract:This paper reports the test results of the first industrial-scale absorption heat transformer (AHT) equipment in China, recovering the waste heat released from mixture of steam and organic vapor at 98 degreesC in coacervation section, synthetic rubber plant, Yanshan Petrochemical Corporation, Beijing, China. The recovered heat is used to heat hot water from 95 degreesC to 105 degreesC, feeding back to the coagulator as heating source. The AHT system is operating with H2O/LiBr solution with heat flow of 5000 kW. The coefficient of performance (COP), the thermal efficiency and the temperature lift of the AHT system are presented. The heat transfer characteristics of the AHT components, i.e. absorber, generator, evaporator and condenser and the solution heat exchanger, are also illustrated by comparison of experimental data and the model calculated results. The results show that the mean COP is 0.47 and the payback period is approximately 2 years.
