高效导向筛板在醋酸甲酯精馏塔技术改造中的研究与应用

Research and Application on High Efficiency Flow-guided Sieve Tray in Methanol-methyl Acetate Distillation Column

在计算机上模拟优化设计了醋酸甲酯的精馏方案。采用新型高效导向筛板塔解决了含发泡物质物系的精馏难点。技术改造后扩产约50％、节能40％左右并提高了产品质量和回收率。技术改造投资30万元、年增经济效益400万元，投资回收期不到1个月。

In the technology reform of methanol-methyl acetate recovery distillation column,the computer was used to simulate the process, and an optimized distillation technology reform plan was obtained.After the technology reform,the product capacity was increased by 50%,the column pressure drop was decreased by 30%～ 50%,the energy consumption was decreased by about 40%.
