摘要
针对MTBE装置扩能改造后萃取塔塔顶碳四出料甲醇含量偏高的问题,以萃取塔的实际运行工况为参考,利用HYSYS流程模拟软件建立计算模型,对萃取塔操作温度、压力、料水比等参数进行计算分析,确定萃取塔操作优化方案并组织实施。实施结果表明,萃取塔碳四出料甲醇含量基本得到控制。
Using HYSYS software and based on the actual running conditions of the extraction tower in MTBE unit,a computer model was set up to calculate and analyze the operation parameters of the extraction tower including temperature, pressure and feed to water ratio. An operation optimization scheme was obtained by the model simulation and it was put into practice to solve the problem of high methanol content in C4 outlet stream after the revamping of MTBE unit. The optimized operation results showed that the methanol content in C4 outlet stream could basically meet the requirement.
