Abstract
The present invention relates to a method and system for the removal of carbon dioxide (CO2) from an upstream gas with a solvent-based system. In particular, the present invention relates to a method and a system for the regeneration of solvents and removal of CO2 from CO2 rich solvent streams wherein the method and system use heat from an upstream gas for the regeneration.
Claims51
A method for regenerating a solvent comprising carbon dioxide (CO2), the method comprising:
- providing a flue gas comprising carbon dioxide (CO2);
- passing the flue gas comprising carbon dioxide (CO2) through a first heat exchanger, wherein heat from the flue gas is exchanged with a fluid to form a heated fluid and a cooled flue gas;
- passing the heated fluid through a regenerator;
- providing a solvent comprising carbon dioxide (CO2);
- passing the solvent comprising carbon dioxide (CO2) through the regenerator, wherein heat from the heated fluid heats the solvent comprising carbon dioxide (CO2) to form a solvent comprising a reduced amount of carbon dioxide (CO2).

A system for regenerating a solvent comprising carbon dioxide (CO2), the system comprising:
- a first heat exchanger;
- and
- a regenerator;
- wherein the first heat exchanger exchanges heat between a flue gas comprising carbon dioxide (CO2) and a fluid to form a heated fluid and a cooled flue gas, and the regenerator exchanges heat between the heated flue gas and a solvent comprising carbon dioxide (CO2) to provide energy for regenerating the solvent by removing carbon dioxide (CO2).
