Abstract
An apparatus for producing hydrogen from an off-gas originating from a gas to liquid (GTL) process is provided. The apparatus includes a cryogenic distillation column, a first CO shift reactor, a second CO shift reactor, an SMR, and a first and second PSA. The cryogenic distillation column is configured to receive an off-gas and separate it into a light ends and a heavy ends. The first CO shift reactor is configured to receive the light ends and, in the presence of steam, produce additional hydrogen and carbon monoxide. The SMR is configured to receive the heavy ends and convert hydrocarbons within the heavy ends to hydrogen and CO, with the resulting stream then being treated in the second CO shift reactor to produce additional hydrogen and CO. The hydrogen is then captured using the first and second PSAs.
