摘要
运用化工过程模拟系统对HCFC-142b装置两级脱气流程进行了物料及能量恒算,确定了塔顶冷凝器的负荷,并且优化了脱气塔的进料位置;同时使用换热器设计核算软件对正在使用的冷凝器进行了核算。计算结果表明:两级脱气塔进料位置分别提升至第28和第10块板,在不更换换热器的前提下,可以把冷媒由-10℃盐水改为循环水。该技术改造已经稳定运行两年,每年节约费用约200万元,取得了良好的经济效益。
The material and energy balance of HCFC- 142 b device was calculated by using chemical process simulation system. The condenser heat of distillation column was determined. Optimal feed position of distillation column,using the heat exchanger software HTRI to calculate the condenser. Calculation results show that the best feeding position is twenty- eighth and tenth,respectively. Under the premise of not replacing the heat exchanger,the cold medium can be changed from the- 10 ℃ to the circulation water. The technical transformation has been successfully run for more than two years,the annual cost savings of two million yuan.
