乙烯裂解汽油抽提苯乙烯工艺中C8C9馏分分离研究

Ethylene Pyrolysis Gasoline Extraction Styrene Process Study on Separation of C8C9

用标准物系对填料商的A系列填料中的传质性能进行了研究,考察了填料的传质性能;用乙烯裂解C8C9馏分原料在某填料商的A系列填料中进行分离考察,确定填料的传质性能及填料的具体型号,达到了C8C9馏分原料分离的目的,通过对填料分布器的实验,确定了分布的形式,该型填料在广东新华粤3万吨/年苯乙烯抽提装置投用后,达到了理想的效果。

In this paper, the mass transfer performance of A packing is studied by means of standard material, and the mass transfer performance of the packing is investigated. Using ethylene cracking C8C9 distillate raw materials in a packing business A series packing separation, determine the packing mass transfer performance and the specific type of packing, achieved the purpose of C8C9 distillate raw material separation, through the experiment of packing distributor, determine the shape of the distribution, the type of packing in Guangdong xinhua yue 30000 tons/year styrene putting-in-service proactively extraction de＇vice, to achieve the ideal effect.
