[". La empresa utiliza tres column de精馏塔进行分离A、B、C三种物质。一塔的塔顶蒸汽(A、B混合物)经过冷凝器冷凝后,根据“回流比”将一部分回至一塔顶部,另一部分至二塔进行进一步精馏(分离B、C)。我考虑直接将一塔顶部的气相通过一个装置直接分成两部分,一部分冷凝回流至一塔,另一部分直接气相进入二塔。这样在能耗上面应该可以省下一部分。 一开始考虑的是塔顶直接装一个冷凝器,但是改造肯定是要花钱的;省一分是一分;后来考虑利用原有的冷凝器和捕集器,调整冷凝水的流量来实现部分冷凝的目的,但是考虑控制起来存在滞后性,加大了操作工的难度; 所以考虑是否有什么设备或者装置可以将塔顶的蒸汽直接分配,一部分直接冷凝回塔作为回流,一部分直接进入二塔。我想应该存在这样的设备,希望群里的大神不吝告知,谢谢!
