为了充分利用C4资源增产甲基叔丁基醚(MTBE),在中海石油宁波大榭石化有限公司催化裂解(DCC)装置上通过回炼醚后C4馏分,考察回炼醚后C4馏分前后装置操作参数、物料平衡、产品分布、产品性质、能耗等的变化。结果表明:DCC装置回炼醚后C4(6.88 t/h)和气分C4(10.06 t/h)后,一部分异丁烷和正丁烷组分在系统中循环,气分C4中异丁烯体积分数由31.48%降至29.83%,液化气、乙烯收率分别增加1.18,0.11个百分点,丙烯收率下降0.09个百分点,装置能耗(以标准油计,下同)增加0.24 kg/t;MTBE装置加工负荷增加17.93个百分点,MTBE产量增加2.69 t/h,收率增加1.16个百分点,醚后C4出装置量降低2.56 t/h,装置能耗降低4.78 kg/t。
- Abstract:
-
In order to increase the production of methyl tert-butyl ether (MTBE) by using C4 resources, the changes of operating parameters, material balance, product distribution, product properties, energy consumption and so on were investigated by reprocessing post-esterification C4 fractions in the deep catalytic cracking (DCC) unit of Ningbo Daxie Petrochemical Co Ltd of CNOOC. The results showed that after reprocessing 6.88 t/h of post-esterification C4 fractions and 10.06 t/h of gas fractionation C4 fractions in DCC unit, some isobutane and n-butane components were circulated in the system. Isobutane in gas fractionation C4 fractions decreased from 31.48% to 29.83%, and the yield of LPG and ethylene increased by 1.18 and 0.11 percentage points respectively. The propylene yield decreased by 0.09 percentage points, and the energy consumption (in standard oil, the same below) increased by 0.24 kg/t. Processing load in MTBE unit increased by 17.93 percentage points, production of MTBE increased by 2.69 t/h, the yield increased by 1.16 percentage points, output of post-esterification C4 fractions decreased by 2.56 t/h, the energy consumption decreased by 4.78 kg/t.
