摘要
为实现资源利用效益最大化,某公司根据催化裂解柴油和蜡油加氢裂化装置进料性质的特点,开展了 2.1 Mt/a环烷基劣质蜡油加氢裂化装置掺炼质量分数5％催化裂解柴油的工业试验.结果表明:环烷基劣质蜡油加氢裂化装置掺炼催化裂解柴油后,喷气燃料产品收率增加1.93百分点,有效提高了喷气燃料的收率;喷气燃料烟点上升1.2 mm,加氢柴油十六烷值升高1.9,改善了喷气燃料、柴油的性质;掺炼催化裂解柴油后,装置精制反应器温升明显增加,氢耗和电耗增加.经测算,掺炼催化裂解柴油后,原来作为燃料油调合组分的催化裂解柴油,转化为附加值较高的重石脑油、喷气燃料及柴油组分,产生利润467.2元/t(以掺炼1 t裂解柴油计),可获得4 036.8万元/a的经济效益.
Abstract
In order to maximize the efficiency of resource utilization,a company carried out an industrial test of mixing about 5％deep catalytic cracking(DCC-plus)diesel fraction into 2.1 Mt/a naphthenic base inferior gas oil hydrocracking unit according to the feed characteristics of DCC-plus diesel and gas oil hydrocracking unit.The industrial test results showed that the yield of jet fuel increased by 1.93 percentage points,the smoke point of jet fuel increased by 1.2 mm,and the cetane value of hydrogenated diesel increased by 1.9,which improved the properties of jet fuel and diesel.After blending DCC-plus diesel,the temperature rise of refining reactor increased obviously,and the consumption of hydrogen and electricity increased significantly.It is estimated that after blending DCC-plus diesel,which was originally used as a fuel oil blending component,was converted into heavy naphtha,jet fuel and diesel components with higher added value.The profit was 467.2 Yuan/t(in terms of DCC-plus diesel),and the economic benefit was 40.368 million Yuan/a.
