DELAYED PETROLEUM FEEDSTOCK COKING PROCESS

摘要

FIELD: petroleum processing and petrochemistry. ^ SUBSTANCE: process comprises: heating petroleum feedstock; coking it in coking chamber while simultaneously withdrawing vapor-gas products and separating them on rectification column; cooling and separating resulting gas-liquid mixture into gas, gasoline, and water; draining water condensate; mixing gasoline with gas followed by separating them; and performing processing to produce coking gas and coking gasoline. Mixing of gas and gasoline is conducted in gas-liquid contactor by tangentially feeding stream of compressed gas preliminarily purified of liquid drop phase into injector-atomized gasoline. Gasoline-atomization injector is constructed in the form of perforated tube provided with bumper disk and mounted along axis of gas-liquid contactor. ^ EFFECT: increased yield of coking gasoline and improved quality of coking gasoline. ^ 2 dwg, 3 tbl
