【摘要】 通过对高压聚乙烯反应系统进行火用计算与分析 ,结果表明 ,由传热不可逆造成的内部火用损为主要的火用损。一、二、三段反应器的内部火用损各占其总火用损的 97.78%、98.87%、85 .44 %。并提出了相应的节能措施和优化方案。更多还原

【Abstract】 In this paper, the exergy calculation and analysis about the reaction system of the high pressure polyethylene were carried out. It showed that the inner exergy losses resulted from irreversible heat-transfer was the main. The ratio of the inner exergy losses to the total exergy losses of the three reaction segments was 97.78? 98.87 and 85.44 percent respectively. A saving energy steps and the optimum schemes were develped.更多还原
