Abstract
A method for producing hydrogen from an off-gas originating from a gas to liquid (GTL) process is provided. The method includes separating the light ends from the hydrocarbons using a cryogenic distillation column and then processing the light ends and the hydrocarbons to produce additional hydrogen product. The light ends are introduced to a CO shift reactor in the presence of steam to convert CO to COand hydrogen. The hydrocarbons are introduced to a steam methane reformer in the presence of steam to convert hydrocarbons to hydrogen and CO. The resulting stream is treated in a second CO shift reactor to produce additional hydrogen and CO. The hydrogen is then captured using a pressure swing absorber.
