Delayed Coking of Spent Oil Distillate PDF

Abstract

A laboratory coking unit was designed and constructed for the experimental study of the delayed coking process of spent oil distillate. The yield and analysis of coke, gases and liquid products were obtained for each experiment. The study showed that spent oil distillate produced relatively low sulphur content coke and with no metals. Increasing the recycle ratio increases the coke yield and decreases the gas and gasoline yield and the olefins content of gasoline. The recycle ratio has a slight effect on the sulphur content of produced coke.
