Patent number: 10370248Abstract: An improved hydrogen generation system and method for using the same are provided. The system includes an HDS unit configured to remove sulfur, a first and second pre-reformers configured to pre-reform a process gas and fuel gas, respectively, a first and second heat exchangers configured to dry and heat the pre-reformed fuel gas, respectively, and a reformer configured to produce a syngas and flue gas. The method includes using a process stream selected from the group consisting of air, PSA off-gas, hydrocarbon gas, and combinations thereof to dry the fuel gas and using a process stream selected from the group consisting of the flue gas, the syngas, and combinations thereof to heat the dry fuel gas. The second pre-reformer is a low-pressure pre-reformer, so that the heat contents of the fuel gas is increased through converting heavy hydrocarbons in the fuel gas to CO and H2 by the second pre-reformer.Type: GrantFiled: January 27, 2017Date of Patent: August 6, 2019Assignees: L'Air Liquide Societe Anonyme Pour L'Etude, Et L'Exploration Des Procedes Georges ClaudeInventors: Taekyu Kang, Rong Fan, Pavol Pranda, Robert A.
