Analysis of the influence of catalyst loading and stage matching on the long-term operation of residual oil hydrogenation
The operation of the B-series residual oil hydrogenation unit with an annual capacity of 3.44 million tons at Sinopec Hainan Refining and Chemical Co.,Ltd.in the past two cycles was studied.By comparing and analyzing the catalyst loading method,grading optimization,reaction CAT,bed pressure difference,bed radial temperature difference,raw material and thermal low separation product properties,and impurity removal rate in the two cycles,theoretical basis was provided for the long-term operation of the residual oil hydrogenation unit.
