Abstract
The present invention provides a process for managing hydrogen in a hydrocarbon gas to liquid plant. The process includes feeding a syngas stream produced by a partial oxidation reactor to a Fischer-Tropsch reactor, thereby converting the syngas to hydrocarbon liquids. It also includes passing a substantially oxygen-free feed stream comprising hydrocarbon gas and water to a steam reformer, thereby producing a hydrogen-rich stream. The H2/CO ratio in the syngas feed stream can be adjusted to a desired value by introducing a first portion of the hydrogen-rich stream to the syngas feed stream. A second portion of the hydrogen-rich stream can be passed to one or more hydrogen users, e.g., a catalyst regeneration unit, in the GTL plant.
