Patent ID: 6860985

Claim:
A method for improving yield in a coking process, comprising: (a) conducting an effluent stream from a coking process to a first separation region; (b) separating at least a light fraction in the first separation region; (c) conducting steam and the light fraction to a second separation region and separating a vapor fraction and a liquid hydrocarbon fraction; (d) conducting the liquid hydrocarbon fraction back to the first separation zone; (e) separating in the first separation region a coker gas oil having a boiling point higher than the light fraction and containing coke; (f) conducting the coker gas oil to a filter and separating a coker gas oil having a reduced coke content during a first step; (g) backflushing the filter to remove accumulated solids during a second step; and (h) soaking the filter with a treatment solution comprising hydrogen peroxide to improve coker gas oil yield during a third step.
