    摘要: Higher molecular weight hydrocarbon compounds or oxygenates are produced from a gas comprising methane in a process comprising the steps of generating synthesis gas (“syngas”) comprising carbon monoxide and hydrogen by reaction of a gas comprising methane with steam and/or an oxidant gas comprising oxygen, producing higher molecular weight hydrocarbon compounds or oxygenates in a syngas conversion process, removing offgas comprising unreacted hydrogen and unreacted carbon monoxide from said syngas conversion process and separating cryogenically unreacted hydrogen from said offgas or from a gas derived therefrom to produce separated hydrogen product that is substantially free of unreacted carbon monoxide and a first cryogenic liquid comprising unreacted carbon monoxide. The unreacted hydrogen is preferably separated from the offgas in a liquid methane wash column. Two advantages of this process are that this cryogenic separation process is more efficient than known pressure swing absorption techniques and that the concentration of carbon monoxide in the separated hydrogen product is sufficiently small that the separated hydrogen product may be used in the hydrogenation of a wax fraction of the higher molecular weight hydrocarbon compounds without further purification or processing.

    摘要: Hydrogen (H2) gas and crude carbon dioxide (CO2) gas are separated from a gaseous mixture thereof. Combustible gas(es) in the crude CO2 gas are combusted to produce heat, at least a portion of which is recovered by indirect heat exchange with at least a portion of the separated H2 gas or a gas derived therefrom. The invention may be integrated with coal-fired power stations to reduce or eliminate emission of harmful components into the atmosphere.

    摘要: SO2 and/or NOx are removed from gaseous CO2 at elevated pressure(s) in the presence of molecular oxygen and water and, when SO2 is to be removed, NOx, to convert SO2 to sulfuric acid and/or NOx to nitric acid. The sulfuric acid and/or nitric acid is/are then removed from the gaseous carbon dioxide to produce SO2-free, NOx-lean carbon dioxide gas. The invention has particular application in the removal of SO2 and/or NOx from carbon dioxide flue gas produced in an oxyfuel combustion process, for example, in a pulverized coal fired power station.

    摘要: Hydrogen is liquefied by a process comprising pre-cooling hydrogen feed gas by indirect heat exchange against pressurized liquefied natural gas (“LNG”) to produce pre-cooled hydrogen feed gas and pressurized natural gas, further cooling at least a portion of said pre-cooled hydrogen feed gas by indirect heat exchange against at least one refrigerant to produce condensable hydrogen gas and expanding at least a portion of said condensable hydrogen gas to produce at least partially condensed hydrogen. One advantage of such a process is that the power consumed during liquefaction is significantly less than that consumed in existing hydrogen liquefaction processes which pre-cool hydrogen feed gas by indirect heat exchange against other refrigerants, e.g. liquid nitrogen.
