摘要
Abstract
In response to the trend of worsening crude oil quality and to improve heavy oil upgrading capabilities,Sinopec(Tianjin)Petrochemical Co.,Ltd.completed the construction of China's independently intellectual property up-flow residue hydrogenation unit in 2020,with the processing capacity of 2.6 Mt/a.The pressure drop advantage of the up-flow reactor is obvious.After large-scale expansion,however,higher requirements are imposed on the internal gas-liquid distribution,and feedstock composition and property change bring challenges to the stable operation of the unit.By primarily optimizing the design parameters of reactor components and the catalyst distribution scheme,the unit has achieved continuous stable operation for 16 months in the third cycle.The pressure drop of the up-flow reactor is no more than 0.29 MPa,with the radial temperature difference lower than 4℃,and the stable hydrogenation performance of the catalyst.The desulfurization rate is 84%,the residual carbon conversion rate is 48%,and the removal rate of metals(Ni+V)is 84%.关键词
