摘要
目前国内绝大部分制药、化工行业常用蒸汽、冷却水和CaCl2或乙二醇水溶液等几种热媒进行工艺流程中的换热。管路复杂、稳定性差、腐蚀大及操作容易出错等。探讨一种特性稳定的、单一的热媒用来改变现状的方法,并就已成功的方案和方法作为推广性地介绍。
Currently,in most of pharmaceutical and chemical enterprises,the mediums for heat transfer in process are often steam,CaCl2 and ethylene glycol solution.In using these mediums,there are disadvantages,such as complicated pipeline,poor stability,strong corrosion and commonly occurred failures.In this article,the method of using stable and unique medium was discussed,and some successful examples were introduced.
