LNG冷能发电的优化设计

Optimal design of LNG cold energy power generation

随着LNG产业的蓬勃发展,构建利用LNG冷能发电系统成为回收冷能的重要途径。通过HYSYS流程模拟软件对朗肯循环进行流程模拟,并根据模拟得到的过程参数以及输出功进行分析,针对系统进行算法优化设计,以系统火用效率最大为目标函数,得到最优的运行参数。

With the vigorous development of the LNG industry, building an LNG cold energy power generation system has become an important way to recover cold energy. In this paper, HYSYS process simulation software is used to simulate the process of Rankine cycle, and to analyze the process parameters and output power obtained by the simulation. The algorithm is optimized for the system, and the maximum operati-ng efficiency is obtained as the objective function of the system.
