FIELD: petroleum processing. SUBSTANCE: gas oil formed in lower flash evaporation zone of fractionating coke column is subjected to filtration to remove suspended solids first on filter and than using hydraulic cleansing. Thus filtered and cleansed gas oil is more suitable for treatment on fluidized catalyst-bed cracking installation or on another installation, whereas removal of solid particles from gas oil on filter allows treatment of gas oil on fluidized catalyst-bed hydrofining installation without risk of clogging (poisoning) catalyst bed. EFFECT: enhanced process efficiency. 3 dwg, 1 tbl
