利用有机工质回收炼油企业中的低温热能

RECOVERY OF LOW TEMPERATURE HEAT ENERGY IN REFINERY USING ORGANIC MEDIUM

降低炼油企业的能耗,有不同的方法和措施,其中利用有机工质回收低温热能发电,也是一种可以应用和发展的手段。笔者根据有机物的低沸点等多种有利于回收低温热能的特性,以异戊烷为例并采用PROⅡ软件进行模拟,指出利用有机物为工质的朗肯循环回收炼油工艺过程的低温热,也是一种十分有效的手段。

Lots of methods and measures have been applied to decrease the energy consumption in refineries, and using organic medium to recover low temperature heat energy for power generation is one of them.Based on the characteristics of organic medium in favor of the recovery of low temperature heat energy including low boiling point,this paper takes i-pentane as the example and uses PROII software for simulation. It points out that it is an effective way to use organic Rankine cycle to recover low temperature heat...
