- Abstract
The model of LNG cold energy recovery consisting of a Brayton cycle and a Rankine cycle is constructed in Aspen Plus. The effects of the inlet and outlet pressure of the turbines, ammonia-water flow rate, condensing temperature and the compressor outlet pressure to the thermal efficiency of the combined power cycle have all been performed sensitivity analysis. The result shows that the thermal efficiency increases with the turbines inlet pressure and the compressor outlet pressure. Meanwhile, decreasing the ammonia-water flow rate and condensing temperature can also achieve such effects.
