摘要
采用日本KBC公司开发的Petro-SIM系列软件中RHDS-SIM模型对390万t/a渣油加氢装置的反应器进行了模拟,分析了模型的准确性,并利用该模型对渣油加氢装置生产低硫船用燃料油的工况进行了优化.结果表明:建立的模型能有效反映装置实际生产工况,主要产品的模拟结果偏差均低于2％;在生产低硫船用燃料油时,为了满足产品含硫量要求,反应器入口温度需升高4℃,化学氢耗增加了 3.5 m3/m3,R1,R2,R3床层催化剂寿命依次缩短了 26.5,30.7,38.3 d.
Abstract
The RHDS-SIM model developed by KBC Corporation was utilized to simulate the reactor of a 3.9 Mt/a residue hydrogenation unit.The accuracy of the model was analyzed,and it was used to simulate the operating conditions of residue hydrogenation unit for producing low-sulfur marine fuel oil.The results showed that the established model effectively represented the actual operating conditions of the unit,simulation deviations of the main product below 2％.In order to meet the requirement of product's sulfur content,during producing low-sulfur marine fuel oil,the reactor's inlet temperature needed to increase by 4 ℃,and the chemical hydrogen consumption increased by 3.5 m3/m3,the catalyst lifespan of R 1,R 2,R 3 beds shortened by 26.5,30.7,38.3 d,respectively.
