Abstract

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

I claim:

1 . A coker-fractionator unit that comprises:
a) a coker furnace that is configured to heat a hydrocarbon feedstock; b) a coker drum that is configured for receiving and coking the heated hydrocarbon feedstock; c) a source of a hydrogen donor gas; d) a first conduit for providing fluid communication from the source of hydrogen-donor gas to upstream of the coker furnace; and e) a second conduit for providing fluid communication from the source of hydrogen-donor gas to downstream of the coker furnace and upstream of the coker drum.

2 . The coker-fractionator unit of claim 1 , further comprising a fractionator for separating a coked product that is received from the coker drum.

3 . The coker-fractionator unit of claim 1 further comprising a switching member that is configured to control an amount of fluid that is communicated from the source of hydrogen-donor gas to at least one of the first conduit and the second conduit.

4 . The coker-fractionator unit of claim 3 , wherein the switching member is configured to be controlled remotely.

5 . The coker-fractionator unit of claim 1 , further comprising one of more sensors that are configured to detect one more physicochemical properties of a fluid within the coker-fractionator unit, the one or more sensors are further configured to electronically communicate one or more detected physicochemical properties to a processing structure.

6 . The coker-fractionator unit of claim 5 , wherein the processing structure is configured to electronically communicate instructions to the switching member to change the amount of the fluid that flows from the source of hydrogen-donor gas between the first conduit and the second conduit.

7 . The coker-fractionator unit of claim 1 , wherein hydrogen-donor gas is introduced into the second conduit at a rate of between 2 wt % to about 15 wt % of a total feed rate of the second conduit.
