Abstract: Sulfur transfer patterns during crude oil processing are very important to crude oil selection, production plan-ning, product blending, technological transformation and modem enterprise management. The sulfur transfer model developed by Engineering Research Institute of Luoyang Petrochemical Engineering Company can be used to predict sulfur content, sulfur distribution, sulfur transfer ratio and overall sulfur balance of the products from secondary processing, such as catalytic cracking, delayed coking, deasphalting with solvent, hydrocracking, hydro-fining, oil residue hydrogenization, viscosity breaking and catalytic reforming. It can provide technical supports to modern enterprise management.
