ReduceMain fractionation tower,s press drop can enhance inlet pressure of compressor.At the condition of compress ratio is invariable,it can improve system pressure、increase NTS of stabilization tower、reduce stabilize gasoline C4 ratio、improve system absorbent ability.Generic design can hardly reach the best NTS of absorber,so adding absorber,NTS can obviously increase effect so absorb. Because adding absorber'NTS can reduce system dependence on other factors,and it can not lead to the increase of the energy,so it is the best economic method of improving absorb operation effect. For desorber,double feed stream is a economical means but it need adding the NTS.

降低主分馏塔的压降，可以提高压缩机的入口压力，在压缩比不变的情况下提高系统压力；增加稳定塔理论板数，可以降低稳定汽油中C4的含量，系统的吸收效果改善；一般的设计和吸收塔的最佳板数相距较大，所以改造吸收塔的理论板数，它对提高吸收效果往往最显著，又因为改善吸收塔的理论板数会降低系统对其它因素的依赖程度，而且改善它并不增加能耗，所以改造它对提高吸收效果又是最经济的手段之一；对于解吸塔来说，双股进料的工艺很有经济效益，但它需要增加理论板数来实现。
