METHOD OF HEATING HYDROCARBON RAW FEEDING FOR THERMIC SPLITTING, MAINLY BASED ON LIGROIN

摘要

FIELD: organic chemistry, hydrocarbons. SUBSTANCE: method involves at least three-stage indirect heat-exchange of raw containing nonhydrogenated C₄-fraction and diluting agent with foam gases of thermic splitting. Raw and diluting agent were passed separately through the corresponding first stage of indirect heat-exchange that involves passing diluting agent in mixture with nonhydrogenated C₄-fraction through the first stage of indirect heat-exchange followed by mixture addition to hydrocarbon raw. EFFECT: improved method of heating.
