Abstract: A method and system for producing a synthesis gas for use in the production of methanol, or a hydrocarbon product such as a synthetic fuel, comprising the steps of: providing a carbon dioxide-rich stream and passing it through an electrolysis unit for producing a feed stream comprising CO and CO2; providing a water feedstock and passing it through an electrolysis unit for producing a feed stream comprising H2; combining said feed stream comprising CO and CO2 and said feed stream comprising H2 into said synthesis gas; and converting said synthesis gas into said methanol or said hydrocarbon product.

Abstract: The present invention relates to a hydrocarbon plant and related process, in which a first feed of methanol, having a water content of less than 10% by weight, is converted in a syngas generation stage (A) into at least a syngas stream. A synthesis stage (B) is arranged to receive the syngas stream and convert it to at least a hydrocarbon product stream and an off-gas stream. The plant and process of the present invention use better-understood process steps compared to known processes/plants and provide the opportunity for a reduction in CO2 emissions.

Abstract: A plant and process for producing hydrogen, comprising: a primary reforming unit arranged to receive a hydrocarbon feed, such as natural gas, and comprising: a combustion section comprising a catalyst suitably for steam methane reforming, and one or more burners for providing heat for said steam methane reforming, for thereby generating a synthesis gas stream and a flue gas stream, and a convection section comprising heat exchangers for thereby generating a cooled flue gas stream; wherein said one or more burners are arranged to receive a preheated combustion air stream and a preheated fuel gas stream derived from a downstream hydrogen purification unit which is arranged to receive at least a portion of said synthesis gas stream, for thereby generating a hydrogen-rich stream and an off-gas stream; and in which the fuel gas stream is a portion of said hydrogen-rich stream i.e. first fuel gas stream, or a gas stream, i.e. second fuel gas stream, resulting from combining at least a portion of said off-gas stream and a portion of said hydrogen-rich stream. The invention relates also to method of retrofitting an existing plant for producing hydrogen.
