Abstract: The present invention concerns a process for the manufacture of one or more useful products comprising: gasifying a carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to generate a raw synthesis gas; optionally partially oxidising the raw synthesis gas in a partial oxidation zone to generate partially oxidised raw synthesis gas; supplying at least a portion of the, optionally partially oxidised, raw synthesis gas to a clean-up zone to remove contaminants and provide a clean synthesis gas; optionally shifting the hydrogen to carbon monoxide ratio of the clean synthesis gas in a hydrogen to carbon monoxide ratio shifting zone to generate shifted clean synthesis gas; supplying the, optionally shifted, clean synthesis gas to a first further reaction train to generate at least one first useful product and a tailgas; optionally upgrading the first useful product in a second further reaction train to generate a second useful product and a light gas fraction; and diverting selectively on demand a portion of at least one of the carbonaceous feedstock, the clean synthesis gas, the tailgas and the light gas fraction to heat or power generation within the process, in response to external factors to control the carbon intensity of the overall process and enable GHG emission savings.

Abstract: In a process for treating wastewater from a combined gasification and Fischer-Tropsch (F-T) process, feedstock derived from Municipal Solid Waste or the like is gasified in a reactor (R) and treated in a cleanup unit (C) which generates a first wastewater stream (1st WWT STREAM) containing salts and inorganic pollutants. The first wastewater stream is treated in a treatment unit (T1) to remove inorganic pollutants derived from the syngas The treatment comprises a) degassing, and subsequently b) neutralising the first wastewater stream before treatment in a Dissolved Air Flotation unit (72c) and filtering in a moving sand bed or similar (72d) to remove solids, and a stripping process to remove ammonia. A second wastewater stream (2nd WWT Stream) containing organic pollutants but being low in salts arises from the F-T process and is treated separately to allow recycling within the F-T process.
