Devices, systems, facilities and processes for CO2 post combustion capture incorporated at a data center
Devices, systems, facilities, and methods for post combustion capture of emissions from a natural gas generator used to power a data center disclosed herein. The facility includes a process for capturing and sequestering CO 2 from a post combustion capture of the natural gas generator utilizing the heat from the flue gas and from the data center. The CO 2 rich streams from the post combustion capture system are sent to sequestration of some form via a sequestration compressor, thereby reducing the overall emissions from the facility.
1. A system for treating, compressing, and sequestering carbon dioxide (CO 2 ) derived from post combustion capture from a natural gas generator, the system comprising: a data center configured to receive power from the natural gas generator for operation; at least one waste heat recovery unit configured to receive flue gas from the natural gas generator and heat from the data center, wherein the at least one waste heat recovery unit is configured to recover heat from the flue gas and from the heat generated by the data center, and the at least one waste heat recovery unit is further configured to send the heat recovered from the flue gas and from the heat generated by the data center to a post combustion capture facility for regeneration; the post combustion capture facility configured to capture the CO 2 from the flue gas from the at least one waste heat recovery unit into a CO 2 stream; a dehydration unit configured to remove water from the CO 2 stream to provide a dry CO 2 stream; and a sequestration compression unit configured to convey the dry CO 2 stream towards a sequestration site.
2. The system of claim 1 , wherein the at least one waste heat recovery unit comprises a heat recovery steam generator configured to generate steam for regeneration.
3. The system of claim 2 , wherein the water separated from the CO 2 stream by the dehydration unit is directed to the heat recovery steam generator.
4. The system of claim 1 , further comprising a blower configured to move the flue gas through the at least one waste heat recovery unit.
5. The system of claim 1 , wherein the data center is configured for cloud storage and/or cryptocurrency mining.
6. A method for treating, compressing, and sequestering carbon dioxide (CO 2 ) derived from post combustion capture from a natural gas generator, the method comprising:
receiving, by a data center, power from the natural gas generator for operation;
receiving, by at least one waste heat recovery unit, flue gas from the natural gas generator and heat from the data center, wherein the at least one waste heat recovery unit is configured to recover heat from the flue gas and from the heat generated by the data center;
sending, by the at least one waste heat recovery unit, the heat recovered from the flue gas and from the heat generated by the data center to a post combustion capture facility for regeneration;
capturing, by the post combustion capture facility, the CO 2 from the flue gas into a CO 2 stream;
removing, by a dehydration unit, water from the CO 2 stream to provide a dry CO 2 stream; and
conveying, by a sequestration compression unit, the dry CO 2 stream towards a sequestration site.
7. The method of claim 6 , wherein the at least one waste heat recovery unit comprises a heat recovery steam generator configured to generate steam for regeneration.
8. The method of claim 7 , further comprising directing, by the dehydration unit, the water separated from the CO 2 stream to the heat recovery steam generator.
9. The method of claim 6 , wherein the at least one heat recovery unit includes a blower configured to move the flue gas through the at least one waste heat recovery unit.
10. The method of claim 6 , wherein the data center is configured for cloud storage and/or cryptocurrency mining.
