  • Systems and methods for heat recovery for carbon capture in oil and natural gas systems
    Patent number: 12546272
    Abstract: A system for carbon capture from engines includes a heat recovery steam generator that receives at least a portion of an exhaust from the engines and utilizes the exhaust to form steam. The system may include a steam turbine that utilizes at least a portion of the steam to generate electricity for the system. The system may include an absorption unit that receives the exhaust after the portion of the exhaust is utilized to heat the feedwater to form the steam and contacts the exhaust with a lean sorbent to cause carbon dioxide within the exhaust to be absorbed by the lean sorbent to form a rich sorbent and a carbon dioxide depleted stream. The system may include a desorption unit that receives the rich sorbent regenerates the lean sorbent utilizing heat from the steam.
