The Solvent-based Carbon Capture Plant (SCCP) enables the development, evaluation and optimisation of a variety of solvents for post-combustion capture and related technologies. It is designed to remove up to 1 tonne/day of CO2 (based on MEA) from an equivalent of approximately 150 kW conventional coal combustion flue gas. The plant incorporates 8m absorber and a cleaned flue gas wash column, re-boiler, desorber column and a condenser on top of the column, and fresh and spent solvent tanks. The absorber and desorber columns are equipped with temperature and differential pressure sensors, solvent sampling ports, provisions for corrosion coupons and alternative materials test sites, and trace gas injection capability. The plant also has an integrated flue gas desulphurisation carbonate wash system. It is controlled and monitored through a dedicated control system. The plant is connected directly to PACT combustion facilities: the 250kW Air Combustion Plant and the 300kW Gas Turbine System, enabling post-combustion capture research from real flue gases from natural gas power plants as well as pulverised fuel combustion plants including coal, biomass and co-firing. The facility is also connected to a dedicated gas mixing facility enabling carbon capture from any synthesised flue gas compositions, including industrial effluent gas mixtures.
