Systems and methods for heat recovery for carbon capture in oil and natural gas systems

A system for carbon capture from a plurality of internal combustion engines, the system comprising:

• a heat recovery steam generator configured to receive feedwater and at least a portion of an exhaust stream from the plurality of internal combustion engines and to utilize the exhaust stream to heat the feedwater to form steam;
• a steam turbine configured to utilize at least a portion of the steam from the heat recovery steam generator to generate electricity to supply power to equipment associated with the system;
• an absorption unit configured to receive the exhaust stream after the portion of the exhaust stream is utilized to heat the feedwater to form the steam and to contact the exhaust stream with a lean sorbent under conditions suitable for carbon dioxide within the exhaust stream to be absorbed by the lean sorbent to form a rich sorbent and a carbon dioxide depleted stream;
• and
• a desorption unit configured to receive the rich sorbent from the absorption unit and to regenerate the lean sorbent utilizing heat from the at least a portion of the steam after the steam is utilized to generate electricity.
