Abstract: A gas-liquid separator comprises a housing having an inlet for receiving a gas- liquid stream and an outlet for discharging a gas stream. An impactor nozzle structure is supported by the housing and situated downstream of the inlet. The impactor nozzle structure receives the gas-liquid stream and accelerates the gas-liquid stream through an orifice that extends through the impactor nozzle structure. An impaction surface is supported by the housing and situated downstream of the orifice. The impaction surface receives the accelerated gas-liquid stream and causes separation of liquid particles from the gas-liquid stream so as to produce the gas stream, and a baffle situated downstream of the impaction surface modifies a flow of the gas stream so as to reduce carryover of liquid particles in the gas stream. A shroud for an inertia! impactor gas-liquid separator is disclosed. A method for separating liquid particles from a gas- liquid stream is disclosed.

Abstract: An inertial gas-liquid impactor separator includes an inertial impactor collector having an impactor surface extending diagonally relative to axially accelerated flow, which surface is preferably a cone having a leading tip axially facing and axially aligned with the acceleration nozzle. In a further aspect, first and second inertial impactor collectors are provided in series, with an orifice in the first inertial impactor collector providing a nozzle for the second inertial impactor collector. Improved performance is provided by reducing the extent of the stagnation region to change from a narrow band particle size range to a wider band range and to shift cut-off size. An inertial gas-liquid impactor separator has a perforated layer of coalescence media having at least one aperture through which the gas-liquid stream flows. Improved performance is provided by increased penetration of the flow into the media patch and thereby enhancing particle capture by interception, impaction and diffusion.
