On the basis of process simulation and basic theoretical analysis, a new energy saving double-column process is proposed for FCC absorption and desorption system with "bi-directional mass transfer".
Various feeding modes of desorbers have been discussed in terms of energy consumption and absorption effect. The intermediate heat exchange process has been provided based on double feeding process.
从能耗和吸收效果两个方面，对解吸塔各种进料方式进行了讨论，在双股进料基础上提出中间换热工艺。
