Carbon capture cooling system and method

摘要

A system and method is provided for capturing a carbonous gas and using the captured carbonous gas for cooling purposes. For example, a system may include a carbon capture system configured to collect a carbonous gas from a syngas, and a cooling system having a gas expander and a coolant circuit that receive the carbonous gas. The gas expander is configured to expand the carbonous gas to reduce a temperature of the carbonous gas to produce a reduced temperature carbonous gas, and the coolant circuit is configured to utilize the reduced temperature carbonous gas to cool at least one solvent of at least one gas purifier.

1. A system, comprising:
a carbon capture system configured to remove a carbonous gas from a syngas to produce a captured carbonous gas, wherein the captured carbonous gas has a purity of at least 80 percent carbon dioxide (CO2) by volume; a cooling system comprising a gas expander and a coolant circuit, wherein the gas expander is configured to expand the captured carbonous gas to reduce a temperature of the captured carbonous gas to produce a reduced temperature carbonous gas, and the coolant circuit is configured to utilize the reduced temperature carbonous gas to cool at least one solvent of at least one gas purifier; and a controller comprising instructions to control the cooling system to control a temperature associated with cooling the at least one solvent of the at least one gas purifier.
