Abstract

Methods and design configurations for regeneration of amine solvents used in carbon dioxide capture and removal are disclosed herein in various embodiments. The present invention describes the use of geothermal energy to regenerate the amine solvent used for CO2 capture from coal-fired power plants or other gas sources. Further, the invention describes a multi-stage striper configuration to regenerate amine solvents from CO2 capture using heat over a range of temperatures. A method involving thermal compression of CO2 from amine solvent regeneration at elevated pressure using heat rather than electricity is also disclosed.
