二甲醚/动力多联产系统初步研究

THE STUDY OF DME/POWER COGENERATION SYSTEM

本文针对两步法二甲醚/动力多联产系统进行了研究。通过对两步法二甲醚生产和动力两个系统的分析整合,使用ASPEN对流程进行了模拟计算,考察了两步法DME和IGCC联产系统的特性。发现两步法DME-IGCC联产与两步法:DME和IGCC分产相比,折合热转功效率提高了5.66个百分点,折合合成能耗下降了26.05％,相对节能率为8.46％。

In this paper a DME/power cogeneration system has been studied. By the mean of simulation, the integration of DME system and power system is completed. The character of DME-IGCC cogeneration system is also assessed. The result shown that the equivalent efficiency of heat converted into power has increased 5.66% compared with the separate generation. The wide applications make the better foreground for the DME-IGCC cogeneration system.
