The PSA off-gas is power plant is first treated in a pre-treatment unit, which compressed, dried and sent to a cryogenic unit, where aims to cool the gas and remove the SOx, HF, HCl, part of the CO₂ is separated from the other components by a the NOx, and dust. [...] solvent stability (no degradation observed), low energy The DMX™ solvent consists of a mixture of two organic compounds in aqueous solution, which is demixing under certain The CO₂-rich solvent is preheated in the lean/rich solvent consumption and purity of the captured CO2 for a wide conditions of temperature and CO2 partial pressure in the regeneration section. [...] Pre-treatment of the flue gas is vital for the operation and economics of the process to result in the optimum effectiveness of the carbon capture technology. [...] The rotating desorber can be is distributed from the inner axis and horizontally flung described as a lightweight pressurised shell-and-tube heat outwards in the direction of the wall of the column, while exchanger where the “hot-side” tube bundle rotates to the flue gas moves vertically from the bottom to the top. [...] The design basis accounted Before entering the core of the capture cycle, the flue for the challenging conditions of the US Gulf Coast and gas heat is recovered, utilising a pressurised clean the Middle East, handling hot ambient temperatures with gas absorber stream to generate an overall surplus of minimised plant cooling and neutral water balance.
