洗化厂换热网络优化

Optimization of Heat Exchanger Networks of the Wash & Chemical Company

对某洗涤剂化工厂脱氢Ⅰ装置换热网络利用夹点方法进行了节能分析及优化设计。新的换热网络较原换热网络减少原换热网络中需热负荷和冷却负荷。避免了公用工程的双重浪费,达到降低操作费用的目的。

Analysis of energy - saving and optimizing design on the heat exchanger network of a Wash ＆ Chemical Company of No Ⅰ dehydrogenatian are made by utilizing the pinch method . Compared with the previous heat exchanger networks , new heat exchanger network reduces consuming energy by reducing heat load and cooling load and avoids wasting cooling and heat load and reaches the aim of reducing total operation cost.
