Abstract

A method and apparatus (100, 200) for producing methanol from a synthesis gas is provided. The method comprises (i) producing, in a partial oxidation (POX) chamber (102, 202), the synthesis gas having a stoichiometric number of less than 1.8 by performing a partial oxidation (POX) process with a hydrocarbon stream and an oxygen stream, (ii) passing, in a water-gas shift reactor (204), the synthesis gas over a water-gas shift catalyst to convert at least a portion of carbon monoxide and water into hydrogen and carbon dioxide, (iii) producing a dry, shifted synthesis gas by separating liquid condensate from shifted synthesis gas, (iv) combining, in a recycle compressor (104, 210), the dry, shifted synthesis gas with a recycle synthesis gas comprised of unreacted synthesis gas and a hydrogen rich product to form a mixed synthesis gas stream, and (v) converting, in a cooled methanol synthesis reactor (214), at least a portion of the mixed synthesis gas stream into methanol.
