| 20100037521 | Novel Steam Reformer Based Hydrogen Plant Scheme for Enhanced Carbon Dioxide Recovery - A novel steam reformer unit design, a novel hydrogen PSA unit design, a novel hydrogen/nitrogen enrichment unit design, and novel processing scheme application are presented. The result of these innovations results in re-allocating most of the total hydrogen plant CO2 emissions load to high pressure syngas stream exiting the water gas shift reactor while minimizing the CO2 emissions load from the reformer furnace flue gas.
