Abstract
Methods and systems for recuperating power from a pressurized fluid stream of a carbon capture system are disclosed. A compressor pressurizes the carbon dioxide containing feed fluid and passes this fluid stream through a carbon capture process. The pressurized stream is expanded across a turbine where power is recovered.
Claims12
A system for recuperating power from a pressurized feed fluid stream of a carbon capture system comprising:
- a compression system configured to receive and compress a feed fluid stream including a carbon dioxide fraction, resulting in the pressurized feed fluid stream, and to direct the pressurized feed fluid stream to the carbon capture system, wherein the compression system comprises a compressor and at least one first heat exchanger;
- wherein the carbon capture system is configured to remove at least a portion of the carbon dioxide fraction resulting in a depleted fluid stream;
- a second heat exchanger downstream of the carbon capture system, wherein the second heat exchanger is configured to heat the depleted fluid stream exiting the carbon capture system;
- and
- a turbine located downstream of the second heat exchanger and configured to receive the depleted fluid stream from the carbon capture system and to extract power from the depleted fluid stream by converting pressure to work through the turbine.
