Abstract
Provided herein a system including a solvent-based carbon capture system, wherein the solvent-based carbon capture system includes an absorber configured to capture carbon oxides from a gas flow via a solvent flow to produce a treated gas flow. The system also includes a water wash system configured to wash the treated gas flow using water. Further, the system includes a cooling system configured to cool the water of the water wash system, wherein the cooling system is configured to circulate a thermal fluid to reduce a temperature of the water in the water wash system.
Claims14
A system, comprising:
- a solvent-based carbon capture system, wherein the solvent-based carbon capture system comprises:
- an absorber configured to capture carbon oxides from a gas flow via a solvent flow to produce a treated gas flow;
- a water wash system comprising first and second water washes configured to wash the treated gas flow using water, wherein the second water wash is downstream from the first water wash along a flow path of the treated gas flow;
- a first sensor disposed along the flow path between the first and second water washes, wherein the first sensor is configured to generate first sensor feedback indicative of a first concentration of solvent in the treated gas flow;
- a plurality of cooling systems comprising a first cooling system and a second cooling system, wherein each of the first cooling system and the second cooling system comprises a heat exchanger configured to cool the water of the water wash system via indirect heat transfer from the water to a thermal fluid, wherein the first cooling system is coupled to the first water wash and the second cooling system is coupled to the second water wash, and wherein the thermal fluid comprises a water-glycol mixture;
- and
- a controller communicatively coupled to the water wash system, the first sensor, and the plurality of cooling systems, wherein the controller is configured to:
- compare the first concentration of solvent to a first threshold value;
- control the plurality of cooling systems to increase cooling of the water to a temperature ranging from about 5° C. to 10° C. in the water wash system and control the water wash system to increase washing of the treated gas flow to increase solvent removal from the treated gas flow when the first concentration of solvent is greater than the first threshold value;
- and
- control the water wash system to reduce washing of the treated gas flow at least by operating only the first water wash coupled to the first cooling system without the second water wash coupled to the second cooling system when the first concentration of solvent is less than or equal to the first threshold value.
