Abstract
Official abstract text for this publication.
Implementations of the present disclosure relate to a method of operating a coker unit comprising the steps of: collecting a coker-furnace feed stream; introducing the coker-furnace feed-stream into a coker furnace for producing a coker-drum feed stream; and introducing a hydrogen-donor gas into either or both of the coker-furnace feed stream or the coker-drum feed stream.
First claim
Opening claim text (preview).
We claim: 1. A method of operating a coker unit comprising the steps of: a) introducing a coker-furnace feed-stream into a coker furnace for producing a coker-drum feed stream; b) introducing the coker-drum feed stream to a coker drum; and c) introducing a hydrogen-donor gas into the coker-drum feed stream, wherein the hydrogen-donor gas is introduced into the coker-drum feed stream at a rate of between 2 wt % to about 15 wt % of a total feed rate of the coker-furnace feed stream, and wherein the hydrogen-donor gas is one of hydrogen, methane, butane, isobutene, a hydrotreater off-gas, and combinations thereof. 2. The method of claim 1 , further comprising a step of introducing the hydrogen-donor gas into a coker-furnace feed stream. 3. The method of claim 2 , wherein the hydrogen-donor gas is introduced into the coker-drum feed stream and the coker-furnace feed stream simultaneously. 4. The method of claim 2 , further comprising a step of alternating between introducing the hydrogen-donor gas into the coker-furnace feed stream and the coker-drum feed stream. 5. The method of claim 1 , wherein the hydrogen-donor gas is methane. 6. The method of claim 1 , wherein the hydrogen-donor gas is butane. 7. The method of claim 1 , wherein the hydrogen-donor gas is isobutene. 8. The method of claim 1 : wherein the hydrogen-donor gas is a hydrotreater effluent. 9. The method of claim 1 , further comprising a step of controlling a first-desired percentage of the hydrogen-donor gas that is introduced into the coker-furnace feed stream. 10. The method of claim 9 , further comprising a step of controlling a second-desired percentage of the hydrogen-donor gas that is introduced into the coker-drum feed stream. 11. The method of claim 10 , further comprising a step of changing the first-desired percentage and the second-desired percentage. 12. The method of claim 1 , further comprising a step of determining one or more physicochemical properties of a fluid within the coker-fractionator unit. 13. The method of claim 12 , further comprising a step of controlling a first-desired percentage of the hydrogen-donor gas that is introduced into the coker-furnace feed stream based upon the step of determining. 14. The method of claim 12 , further comprising a step of controlling a second-desired percentage of the hydrogen-donor gas that is introduced into the coker-drum feed stream based upon the step of determining.
