Abstract
<PICT:0586758/III/1> In a process for the removal of carbon monoxide from impure hydrogen or gaseous mixtures containing hydrogen by treating with steam in the presence of a catalyst in a plurality of stages, the gas stream mixture leaving one stage of carbon monoxide conversion passes directly without cooling to an absorber, round which is circulated a hot aqueous solution of an absorbent, and thence directly to a succeeding conversion stage. In one embodiment, the gaseous mixture is mixed with steam, heated in heater 3, and passed into a converter 4 containing one or more layer of catalyst 5 such as a promoted iron oxide type. The resulting gas-steam mixture is passed directly to an absorber 6 containing a solution of alkali hydroxide, in which the sensible heat of the entering gaseous-mixture is utilised to saturate with water vapour the exit gaseous-mixture which is passed, with addition of further steam if necessary, to a second heater 8 and converter 9. In a modification, the sensible heat of the converted gas-steam mixture leaving the last stage of conversion is utilised for heating water which is subsequently employed for heating and saturating the initial gaseous mixture, the amount of steam added being regulated by allowing a part of the gaseous mixture to pass through a saturator and mix with the part which is bye-passed before proceeding to the first stage of heating and conversion. Where a solution of organic absorbent, such as ethanolamine, is employed, a heat exchanger is incorporated in the circuit, by means of which partially spent absorbent leaving the absorber is heated by the regenerated or partially regenerated absorbent leaving the regenerator to be recirculated to the absorber after suitable cooling. The organic compound and alkali hydroxide may be used as absorbents in the initial and final stage or stages of conversion respectively. The absorbers may be suitably insulated against thermal losses so that the amount of water evaporated increases on proceeding from the first to the last stage of conversion.
