An engine system for removing condensed water may comprise an engine including a plurality of combustion chambers generating driving torque by combustion of fuel; an intake line, in which fresh air flows into the combustion chambers; an exhaust line, in which exhaust gas flows, having been exhausted from the combustion chambers; and an intercooler for cooling compressed air by a compressor of a turbocharger, the intercooler having a coolant circulation line in which coolant flows for cooling the engine.

A system including a gas turbine system including a compressor configured to compress an oxidant; a combustor configured to receive and combust a fuel; a turbine driven by combustion products from the combustor; an exhaust gas recirculation system configured to recirculate exhaust gas along an exhaust recirculation path; and an inlet sensor adjacent to the inlet of the compressor, the inlet sensor detects one or more characteristics; a generator driven by the turbine, wherein the generator generates electrical power and exports to an electrical grid; and a control system including: one or more dampers along the exhaust recirculation path and actuatable between open and closed positions; and a controller configured to receive sensor data, the sensor data associated with a characteristic at the inlet; and modulate at least one of the dampers based on the received sensor data to control an amount of exhaust gas injected into the compressor.

A gas processing system comprises a compressor, an engine configured to drive the compressor, and a control system with emissions quantification capabilities. In some examples, one or more emissions lines direct leakage emissions from the compressor to the engine to be ingested as an alternate fuel source. One or more oxygen sensors generate oxygen sensor data indicating oxygen levels in an exhaust stream of the engine. The control system determines an actual air-fuel ratio of the exhaust stream based at least in part on the oxygen sensor data. The control system determines an error correction corresponding to an adjustment in the air-fuel mixture supplied to the engine to compensate for a difference between the actual air-fuel ratio and a commanded stoichiometric air-fuel ratio. The control system quantifies the leakage emissions from the compressor based at least in part on a comparison of the error correction to a baseline error correction.
