Abstract
The invention described herein relates to a novel process for reducing the carbon dioxide emissions from a coal and/or biomass liquefaction facility by utilizing a steam methane reformer unit in the complex designed to produce additional hydrogen which can be thereafter utilized in the process, as required for the plant fired heaters (including the SMR furnace), and for the production of plant steam. The plant light ends (C1, C2, etc.), which are normally utilized as fuel gas streams are the primary feeds to the SMR Unit along with the tail gas purge from a gasification complex within the facility.
