摘　　要：通过对原有C9分离装置的技术改造,使精馏塔的分离效果达到了厂方的要求。改造过程中采用了高效规整填料、新型塔盘、散堆填料相结合的形式,使整塔压降大幅减小,操作温度降低。不但提高了整塔的抗堵塞性能,而且减小了双环戊二烯的解聚程度,从而提高了产品双环戊二烯馏分的收率。Owing to the renovation of the C9 separation system, the separation effect satisfied the plant requirements. The combination of efficient structured packing, new type trays and random packing greatly reduces the whole pressure drop and operating temperature of the tower. Not only the anti-clogging performance of internals is improved, but also the degree of depolymerization of clicyclopentadiene is reduced, thus improving the yield of dieyclopentadiene fraction.
