摘　　要：管壳式换热器作为一种高效换热装置在石化领域得到广泛应用,但传统计算方法非常复杂,因此软件设计已逐步代替传统手算方法成为工程设计人员的主要设计手段。本文通过对含氢气、一氧化碳、氮气等气体的合成气冷却器进行设计,探讨了管壳式换热器的选型原则,介绍了Aspen EDR设计软件使用要点,详细阐述了Aspen EDR软件设计和校核管壳式换热器的步骤,着重介绍了气体冷却器设计过程中换热器的参数选取及要点,并对设计过程中碰到的问题及调整优化方法进行了简单介绍。设计结果表明,Aspen EDR软件设计的结果不仅能达到工艺要求,而且计算过程快捷明了,极大简化了手工计算的过程,提高了设计效率。As an efficient heat exchanger,shell-and-tube heat exchanger was widely used in petrochemical production,and the conventional design way is very complex.The heat exchanger design software has gradually replaced the traditional calculation method,and has become the main design method for engineers and manufacturers of heat exchangers.In this paper,the steam condenser containing non-condensable gas H2,CO,N2 is designed,and described the process designing and verifying the shell-and-tube heat exchanger by discussing an example of using Aspen EDR software.The selection of parameters and the emphases in the synthesis gas are emphatically introduced.Besides,the problems encountered in the design were analyzed,and the adjustment strategy was determined.Finally,the design meets the requirements of the process.Using ASPEN EDR software to design the shell-and-tube heat exchanger can save a lot of manual calculation process and improve the efficiency of the designer.
