A novel power-producing concept is disclosed, employing a rotating-plate radial gas turbine in various gas-turbine cycle configurations. The “rotating-plate radial gas turbine” is a rotating barrel with robust rectangular plates fitted into the turbine rotor, performing the function and the role of turbine blades, contained within a motionless rigid horizontal cylinder (casing). Combustion can take place in the spaces confined between adjacent rotating plates and the static cylinder, thus enabling a practical achievement of the Atkinson cycle (constant-volume heat addition) with improved cycle thermal efficiency. Alternatively, two or more compressor stages can be combined to feed a single rotating-plate radial gas turbine in cascades, thus gradually increasing pressure of working gas within a volume bordered by adjacent un-cooled rotating plates of the radial gas turbine and the casing. Alternatively, a single compressor may be combined with one or more stages of an axial turbine for cascade feeding of a single rotating-plate radial gas turbine. This “isochoric stuffing” effect enables achievement of significantly and even drastically improved gas-turbine-cycle thermal efficiencies. Cycle heat addition may be either isobaric or isochoric in either an open-cycle or a closed-cycle configuration. Using a sufficiently efficient radial gas turbine, it is theoretically possible to obtain 100% cycle thermal efficiency in a simple radial-gas-turbine configuration with appropriately chosen compressor-stages compression pressure ratios.

The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.
