(FR2780391-A1)   NOVELTY - The process is simplified and the number of items of equipment reduced, whilst maintaining high yield and purity of hydrogen. There are fewer separation columns and the scrubbing column and the distillation column for separating carbon monoxide and methane have been eliminated. The installation for this process requires only two stripping columns and two phase separators    USE - Recovery of carbon monoxide and hydrogen from a mixture containing these gases and methane    ADVANTAGE - Total recovery of hydrogen at a pressure greater than that of prior art systems    (JP2000065469-A)   NOVELTY - The process is simplified and the number of items of equipment reduced, whilst maintaining high yield and purity of hydrogen.
