Energy saving and heat recovery in carbon dioxide compression systems and a system for accomplishing the same

摘要

A method and apparatus for capturing heat at a power plant is disclosed. The method includes absorbing the heat released from carbon dioxide gas from the power plant using a refrigerant (130); transferring the absorbed heat from the refrigerant (130) to a water condensate (115) obtained at the power plant to raise a temperature of the water condensate (115); and supplying the heated water condensate (115) to the power plant to capture the heat released from the carbon dioxide. A power plant and using the methods disclosed herein captures heat from carbon dioxide exhaust and generates power using in part on the captured heat.
