3万t/a甲醇精馏装置的技术改造

Technical reformation of 30 kt/a methanol distillation equipment

对联醇生产中3万t/a的粗甲醇精馏塔进行设计改造,采用装填高效填料的填料塔代替原塔,以达到提高产品质量、节能降耗的目的。成本核算表明该设备投资为32.5万元,利润增加136.5万元,投资回收期为79天。

Crude methanol distillation tower with 30 kt/a capacity was designed and revamped in co-production of methanol. Structured packing is used in the methanol distilling column. The new packing gives superior performance over the conventional trays.These will improve quality of the product, save energy, and reduce cost. The cost-accounting shows that the equipment investment will cost 325 thousand Yuan RMB, but the profit will be increased by 1.365 million Yuan RMB and the return period of the investment will b...
