System and method of heat integration for a gas capture system

A system, comprising:

• a gas turbine system;
• a heat recovery steam generator (HRSG);
• a steam turbine system;
• a carbon capture system;
• and
• an intake heating system comprising one or more heat exchangers, wherein the one or more heat exchangers are configured to:
• receive steam from the HRSG, the steam turbine system, or a combination thereof;
• receive an air;
• place the steam in a heat exchange relationship with the air to produce a heated air and a cooled steam;
• send the cooled steam to the carbon capture system;
• and
• send the heated air to an injection location of the gas turbine system;
• and
• a controller comprising a memory and one or more processors, wherein the controller is configured to:
• adjust one or more parameters of the steam to:
• maintain a first temperature of the heated air between a first lower temperature threshold and a first upper temperature threshold;
• and
• maintain a second temperature of the cooled steam between a second lower temperature threshold and a second upper temperature threshold.

A method, comprising:

• receiving steam from a heat recovery steam generator (HRSG), a steam turbine system, or a combination thereof, into at least one heat exchanger of an intake heating system;
• receiving an air into the at least one heat exchanger;
• transferring heat from the steam to the air in the at least one heat exchanger to produce a heated air and a cooled steam;
• sending the cooled steam to a carbon capture system;
• sending the heated air to an injection location of a gas turbine system;
• and
• adjusting, via a controller, one or more parameters of the steam to:
• maintain a first temperature of the heated air between a first lower temperature threshold and a first upper temperature threshold;
• and
• maintain a second temperature of the cooled steam between a second lower temperature threshold and a second upper temperature threshold.
