Abstract: In order to grasp the market opportunity of IMO 2020′s low sulfur marine bunker oil policy and accelerate the production plan of low sulfur marine bunker oil, SINOPEC Shanghai Petrochemical Company Limited actively arranged the production of low sulfur marine bunker oil by using the residue from residue hydrotreating unit. The bench test oil production was started in September 2018, and the option has been continuously summarized and optimized. By the end of July 2020, a total of 235.7 kt marine bunker oil with low sulfur content had been produced and sold. The process of trial production and formal production of low sulfur marine bunker oil in the fixed bed residue hydrotreating unit was summarized, and the factors affecting the quality of low sulfur marine fuel oil were discussed. The influence of producing low sulfur marine bunker oil on the unit operation was analyzed, and corresponding suggestions for producing low sulfur marine bunker oil were analyzed.
