According to one embodiment of the present invention, a process for washing a syngas is disclosed. The process includes cooling a syngas stream to a temperature below the dew point of water. The cooled syngas stream has at least a condensed-liquid phase and a gas phase. The condensed-liquid phase contains at least one nitrogen contaminant. The process further includes separating the condensed-liquid phase of the cooled syngas stream from the gas phase of the cooled syngas stream. The process further includes removing a majority of the at least one nitrogen contaminant from the condensed-liquid phase to produce a partially-decontaminated liquid stream. The process further includes washing at least a portion of the separated gas phase of the cooled syngas stream with the partially-decontaminated liquid stream.
