摘要
介绍了燕山石化1.3Mt/a中压加氢裂化装置增设中温高压、低压分离器的改造效果。通过增设中温高压、低压分离器,解决了夏季冷后反应产物温度偏高的问题,减少了低分油中稠环芳烃析出,避免了低分油中稠环芳烃污染分馏进料换热器的问题,降低了冷高压分离器的负荷,减少了液相油品的热量损失,每年可节约成本233.67万元。
medium temperature（190 ℃）high and low pressure separators were installed at the 1.3 Mt/a medium pressure hydrocracking unit of SINOPEC Beijing Yansan Company to solve the problem of reaction product temperature in excess of design temperature during summertime. The operation results post to revamping showed that the cooled reaction product temperature well met the design target, besides, less fusedring aromatic hydrocarbons were settled out, which could avoid the contamination of heat exchanger, the load of cold high pressure separator was reduced and the heat lost of liquid product was lowered as well. A saving production cost of 2. 3367 million RMB was obtained annually.
