总公司炼油厂北常减压装置年加工原油250万吨。为了提高换热终温,提高换热网络的热回收牢,我们与清华大学化学化工系协作,进行了换热流程的优化改造。优化流程是运用系统工程的方法,通过换热网络的最优综合和电子计算机的模拟优化,先后进行过十余次电子计算机计算及方案比较最终设计而成。本流程共有48台换热器,采用一路多次和多路并联换热,使原
North Refinery refinery North atmospheric processing of 2.5 million tons of crude oil. In order to improve the final heat transfer and heat recovery network to enhance the prison, we and Tsinghua University Department of Chemical Engineering collaboration, the optimization of the heat transfer process transformation. Optimization process is the use of systems engineering methods, through the optimal synthesis of heat exchange networks and computer simulation optimization, has conducted more than ten times the calculation of electronic computers and the final comparison of the program design. This process a total of 48 heat exchangers, using all the way to multiple and multiple parallel heat exchange, so that the original
