摘要
9万吨/年C_4抽提丁二烯装置对萃取精馏塔再沸器进行了技术改造,解决了换热不好的问题,在一定程度上降低了装置的能耗,改造收到了预期的效果。
After the technical remoulding of extraction rectifying column an heat exchanger in 90 kt/a butadiene extraction device,The remoulding solved the problem of bad syetem heat.To a certain extent it reduced the energy consumption of the device.The remolding obtained good effection.
