摘要
介绍了聚乙烯醇装置回收工序流程,利用化工流程模拟软件PRO/Ⅱ对该流程进行了模拟,指出选择正确的热力学方法是流程模拟的关键。模拟结果表明,物料平衡的模拟值与实际值相吻合,回收所得的甲醇、醋酸、乙醛等产品纯度及回收率均符合装置实际生产要求。
The recovery section of polyvinyl alcohol plant was introduced. The process simulated by application of chemical process simulation software PRO/Ⅱ , key of the simulation was that the thermodynamic method should be correct. The results showed that the simulated numerical value of material balance was consistent with the actual one, and the simulated purity and the recovery volume of methanol, acetic acid, acetaldehyde, etc. were in line with requirements of practical production.
