Claim:
1. A gas-liquid separator, the gas-liquid separator comprising: a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream, the housing defining a central compartment; an impactor nozzle structure supported by the housing within the central compartment and situated downstream of the inlet, the impactor nozzle structure receiving the gas-liquid stream and accelerating the gas-liquid stream through an orifice that extends through the impactor nozzle structure; an impaction surface supported by the housing within the central compartment and situated downstream of the orifice, the impaction surface receiving the accelerated gas-liquid stream and causing separation of liquid particles from the gas-liquid stream so as to produce the gas stream, an impactor shroud extending from a perimeter of the impaction surface and has a free end that extends towards the impactor nozzle structure; the impactor shroud positioned downstream of the impaction surface and within the central compartment; a baffle situated downstream of the impaction surface, downstream of the impactor shroud, and within the central compartment, the baffle extending from the free end of the impactor shroud, the baffle modifying a flow of the gas stream so as to reduce carryover of liquid particles in the gas stream; and a vortex finder ring positioned downstream of the impactor shroud, the vortex ring finder ensuring that larger re-entrained liquid particles are caught on the vortex finder ring and do not exit via the outlet.
