LNG冷能发电技术分析对比

Analysis and comparison of LNG cold power generation technology

总结了目前主流的LNG冷能发电技术,并分析比较了各自的优势和局限性。同时利用Aspenhysys软件模拟了几种主流的LNG冷能发电方案,并对各方案发电量和冷能回收效率进行对比,以优化LNG冷能发电技术,为提高LNG冷能回收效率提出建议。

With the increasing import volume of LNG in China,more attention has been paid to the recycling and utilization of LNG cold energy.In the traditional gasification process,LNG cold energy will be taken away by seawater or air,resulting in energy waste.In order to respond to the strategic demand of energy conservation and environmental protection,it becomes very important to recycle and utilize LNG cold energy and reduce energy loss.This paper summarizes the current mainstream LNG cold power generation technology,and analyzes and compares their advantages and limitations.At the same time,Aspen Hysys software was used to simulate several mainstream LNG cold energy power generation schemes,and the electricity generation capacity and cold energy recovery efficiency of each scheme were compared,so as to optimize the LNG cold energy power generation technology and put forward Suggestions for improving the cold energy recovery efficiency of LNG.
