Abstract: A system includes a condensate injection system configured to fluidly couple to a combustion chamber of a reciprocating engine and an exhaust gas recirculation (EGR) system of the reciprocating engine. The condensate injection system includes a condensate tank configured to store condensate collected from the EGR system. The condensate injection system also includes a pump fluidly coupled to the condensate tank. The condensate injection system also includes an injector fluidly coupled to the pump. The injector is configured to inject condensate into the combustion chamber during a first portion of an engine cycle of the reciprocating engine. The first portion of the engine cycle includes at least part of a power stroke and/or an exhaust stroke of the engine cycle.

Abstract: In certain embodiments, a hydrocarbon processing site may include an internal combustion engine that, during operation, generates an exhaust gas and one or more hydrocarbon processing components that receive a process fluid, output a first portion of the process fluid via a first outlet, and output a second portion of the process fluid via a second outlet. The hydrocarbon processing site may also include a combi-flare that includes an exhaust stack of the internal combustion engine and a flare section. The exhaust stack receives the second portion of the process fluid and the exhaust gas, and the second portion of the process fluid and the exhaust gas operationally mix within the exhaust stack. Additionally, the flare section generates a flame to burn the mixture of the second portion of the process fluid and the exhaust gas.

Abstract: A gas compression system may include a gas compressor having a compressor rod, a piston, and an interior chamber. The gas compressor may receive a process gas at a first pressure, pressurize the process gas via the piston, and output the process gas at a second pressure higher than the first. Additionally, an internal combustion engine coupled to the gas compressor may, during operation, actuate the compressor rod and generate exhaust gas. The gas compression system may also include a packing case, disposed around the compressor rod and fluidly coupled to the interior chamber. The packing case may receive and direct the exhaust gas to counter a flow of the process gas through the packing case from the interior chamber.
