Abstract:
A water gas shift reaction is carried out on a feed gas comprising carbon monoxide to produce carbon dioxide and hydrogen gas. The feed gas is split into multiple input streams flowed into respective reactors coupled in series. Steam is supplied to the input stream fed to the first reactor. The shift reaction is carried out in each reactor, with an overall reduced consumption of steam relative to the amount of gas shifted. The water gas shift reaction may be performed in conjunction with removing acid gas compounds from a process gas such as, for example, syngas or natural gas, by flowing a feed gas into a desulfurization unit to remove a substantial fraction of sulfur compounds from the feed gas and flowing the resulting desulfurized gas into a CO 2  removal unit to remove a substantial fraction of CO 2  from the desulfurized gas.

Claim (Index 23):
A gas processing system, comprising:\n a desulfurization unit configured for removing a substantial fraction of one or more sulfur compounds from a process gas to produce a desulfurized gas; a CO 2  removal unit positioned downstream from the desulfurization unit, and configured for removing a substantial fraction of CO 2  from the desulfurized gas; and a water-gas shift unit positioned upstream or downstream from the desulfurization unit, the water-gas shift unit comprising: a flow splitter configured for splitting a flow of feed gas comprising carbon monoxide (CO) into at least a first feed gas stream, a second feed gas stream, and a third feed gas stream; a first input gas line configured for conducting a first input gas stream, the first input gas stream comprising a combination of the first feed gas stream and steam; a first shift reactor comprising a first vessel, a first shift catalyst disposed in the first vessel, a first inlet configured for conducting the first input gas stream into the first vessel, and a first outlet, wherein the first shift reactor is configured for reacting the CO and the steam in the first input gas stream in the presence of the first shift catalyst to produce a first product gas stream comprising carbon dioxide (CO 2 ) and hydrogen (H 2 ); a first product gas line configured for receiving the first product gas stream from the first outlet; a second input gas line configured for conducting a second input gas stream, the second input gas stream comprising a combination of the second feed gas stream and the first product gas stream; a second shift reactor comprising a second vessel, a second shift catalyst disposed in the second vessel, a second inlet configured for conducting the second input gas stream into the second vessel, and a second outlet, wherein the second shift reactor is configured for reacting the CO and the steam in the second input gas stream in the presence of the second shift catalyst to produce a second product gas stream comprising CO 2  and H 2 ; a second product gas line configured for receiving the second product gas stream from the second outlet; a third input gas line configured for conducting a third input gas stream, the third input gas stream comprising a combination of the third feed gas stream and the second product gas stream; and a third shift reactor comprising a third vessel, a third shift catalyst disposed in the third vessel, a third inlet configured for conducting the third input gas stream into the third vessel, and a third outlet, wherein the third shift reactor is configured for reacting the CO and the steam in the third input gas stream in the presence of the third shift catalyst to produce a third product gas stream comprising CO 2  and H 2 .
