TDI装置中的四氯化碳脱除塔进行了模拟分析,对现场的工艺操作参数进行了优化,塔回流量从600kg/h降低至200kg/h,使得设备节能效率在42%以上,设备生产能力提高约136.5%,年节能费用为54.27万元。 The CTC removal tower in TDI plant was simulated and the operation parameters of the plant were optimized. The return flow rate of the tower was reduced from 600kg / h to 200kg / h, making the equipment more than 42% energy-saving efficiency. Equipment production Capacity increased by about 136.5%, the annual energy cost of 54.27 million.
