Flue gas is compressed to high pressures, which raises the partial pressure of carbon dioxide thus facilitating its absorption into physical solvents (e.g., water, salt solutions, methanol). When added onto an existing CO2-producing process, the compression is performed using multiple stages with intercooling. After the high-pressure carbon dioxide dissolves into the physical solvent, it flows through a series of pressure letdowns using turbines that allow the dissolved carbon dioxide to evolve from the solvent. Through a series of multiple compression stages, the evolved gas is compressed for transport, utilization, or storage. The flue gas that has been scrubbed of carbon dioxide flows through a series of expanders with interheating supplied from waste heat, or the heat of compression. The process is enhanced by employing alkalis that chemically react with acid gases, such as carbon dioxide. These same CO2-capture processes can be integrated into processes that produce shaft and / or electrical power.
