METHOD OF PRODUCING LOW-SULFUR PETROLEUM COKE Russian patent published in 2017 - IPC C10B55/00 

FIELD: oil and gas industry.

SUBSTANCE: process comprises preparing a primary feedstock from a mixture of petrochemical residues and/or refinery residues and light fraction of liquid products of delayed coking - a mixture of light and heavy gas oils in amount up to 10%, producing the secondary feedstock with the temperature of not more than 300°C by mixing the feedstock with a portion of the bottom residue of the rectification column with the heavy-boiling fraction of the coking distillate in the mixer, heating the secondary feedstock in the furnace up to coking temperature, subsequent supply through mixing unit into a coking reactor to produce coke and distillate products of coking.

EFFECT: method makes it possible to increase the yield of coke and target products, while maintaining the inter-repair run of the furnace, reduced power and operating costs for heating and pumping light fraction.
