针对国内某化工企业醋酸装置成品塔塔板腐蚀坍塌严重,产能不达标、产品指标不佳、能耗大等问题,对醋酸装置成品塔塔内件进行技术改造。主要改造内容:塔板采用MFV高效塔板技术。改造后,产能和产品质量满足设计要求,装置的能耗大为降低。 Aiming at the problems of serious corrosion and collapse of finished product tray of acetic acid plant in a domestic chemical enterprise, non-compliance of production capacity, poor product index and high energy consumption, the technological transformation of the inner part of the tower of the acetic acid plant was carried out. The main transformation content: Trays using MFV efficient tray technology. After transformation, capacity and product quality to meet the design requirements, the device greatly reduce energy consumption.
