Abstract
Process and apparatus for producing a H2-containing product and a CO-containing product with CO-containing product turndown capability. The H2-containing product is produced in a process train with a shift reactor and pressure swing adsorption unit. The CO-containing product is produced in a process train with a CO2 removal unit and a cryogenic separation unit. During the CO-containing product turndown mode, a portion or all of the CO-containing product is passed to the shift reactor in the H2-containing product train to form additional H2.
