以CPP裂解石脑油为原料制取芳烃

Production of Aromatics With CPP Cracking Naphtha as Raw Materials

针对以CPP工艺产生裂解石脑油经过加氢去除二烯烃、烯烃及硫化物,按照裂解石脑油苯及甲苯含量及产量,对苯及甲苯进行分离,芳烃抽提装置采用中国石油化工集团石油化工科学研究院开发的环丁砜抽提蒸馏工艺(SED),以裂解加氢石脑油为原料生产苯、甲苯产品,副产抽余油和C8产品,装置于2011年9月10日开始施工,2012年5月建成,6月29日投产,产品合格。

After removing alkadiene, alkene and sulfide in cracking naphtha fi＇om CPP process through hydrogenation, benzene and toluene are separated according to benzene and toluene content in cracking naphtha. Aromatic extraction unit with sulfolane extractive distillation process（SED） developed by Sinopec petrochemical science research institute can produce benzene and toluene with cracking hydrogenation naphtha as raw materials and extract residual oil and C8 as by-products. In our company, construction of the SED Unit started on Sep. 10, 2011, and it＇s completed in May of 2012, and finally was put into operation with the output of qualified products on June 29 of the same year.
