Integration of low-level waste heat recovery and Liquefied Nature Gas cold energy utilization

摘要：

In this paper we proposed two novel thermal cycles based on Brayton cycle and Rankine cycle respectively, which integrate low-level waste heat recovery and Liquefied Nature Gas (LNG) cold energy utilization for power generation. Through the system synthesis, low-level waste heat, low-temperature exergy and pressure exergy of LNG are utilized efficiently. The simulations are carried out using the commercial Aspen Plus 10.2, and the results are analyzed. Compared with the conventional Brayton cycle and Rankine cycle, the two novel cycles bring 60.94％ and 60％ respectively in exergy efficency.
