On what terms HT/ MT/LT shift converters are decided for Hydrogen unit?

It depends on the amount of H2 required by converting CO to CO2. Also steam generation requirement is a consideration. 3 stage would result in higher steam generation with lower CO in outlet process gas thereby improving H2 content however additional pressure drop can be an issue in some cases where final pressure at inlet of PSA in H2 unit can be low.
