丁二烯装置第二精馏塔技术改造

Technology alteration for second distillation column of butadiene plant

对丁二烯装置第二精馏塔进行了技术改造,采用导向浮阀塔板代替原有的F1型浮阀塔板。实践证明,使用高效导向浮阀能使装置的处理能力提高10%,同时稳定了操作,提高了效益。

The second distillation column of butadiene plant is changed used the guide float valve column plate instead of original F_(1) type float valve column plate.The results show that it can increase the plant capacity by 10%,and also make the operation more steady,enhance the benefit of plant.
