Technical reform for distillation system of C_9 fraction
Zeng Aiwu · Chemical Engineering(China) · 2012
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 dicyclopentadiene is reduced,thus improving the yield of dicyclopentadiene fraction.
