Liquid/gas separation
First Claim
1. Apparatus for removing entrained liquid from a gas stream, the apparatus comprising a casing having a substantially circular-cylindrical inner surface and designed to be mounted so that the cylindrical axis is substantially vertical, an inlet port into the casing adjacent to the upper end thereof, a gas outlet port from the casing adjacent to the upper end thereof, drain means at the lower end of the casing whereby separate liquid may be drained therefrom, a gas outlet tube disposed substantially vertically within the casing substantially coaxial with the inner surface of the casing and extending downwardly from the upper end thereof, the outlet tube communicating at its upper end with the gas outlet port, a plurality of baffeles arranged in an annulus around the outer surface of the outlet tube, the baffles being located downstream of the inlet port and shaped to impart a spinning movement to the incoming gas stream, and an impingement plate located downstream of the baffles and having an upper surface extending transversely across the path of the gas stream leaving the baffles and disposed to direct the gas stream onto the inner surface of the casing, the lower end of the gas outlet tube lying below the level of the impingement plate and above the level of the drain means.

Abstract
Apparatus for removing entrained liquid from a gas stream comprises a cylindrical casing (67) designed to be mounted so that its axis is substantially vertical. An inlet port (62) and a gas outlet port (63) are provided adjacent to the upper end of the casing and drain means (80) are provided at the lower end of the casing whereby separated liquid may be drained therefrom. A gas outlet tube (75) coaxial with the inner surface of the casing, extends downwardly from the upper end thereof, the outlet tube communicating at its upper end with the gas outlet port (63). A plurality of baffles (72) are arranged in an annulus around the outer surface of the outlet tube (75), the baffles being located downstream of the inlet port (62) and shaped to impart a spinning movement to the incoming gas stream. An impingement plate (77) is located downstream of the baffles and has an upper surface extending transversely across the path of the air stream leaving the baffles. The lower end of the gas outlet tube (75) lies below the level of the impingement plate and above the level of the drain means.

- 1. Apparatus for removing entrained liquid from a gas stream, the apparatus comprising a casing having a substantially circular-cylindrical inner surface and designed to be mounted so that the cylindrical axis is substantially vertical, an inlet port into the casing adjacent to the upper end thereof, a gas outlet port from the casing adjacent to the upper end thereof, drain means at the lower end of the casing whereby separate liquid may be drained therefrom, a gas outlet tube disposed substantially vertically within the casing substantially coaxial with the inner surface of the casing and extending downwardly from the upper end thereof, the outlet tube communicating at its upper end with the gas outlet port, a plurality of baffeles arranged in an annulus around the outer surface of the outlet tube, the baffles being located downstream of the inlet port and shaped to impart a spinning movement to the incoming gas stream, and an impingement plate located downstream of the baffles and having an upper surface extending transversely across the path of the gas stream leaving the baffles and disposed to direct the gas stream onto the inner surface of the casing, the lower end of the gas outlet tube lying below the level of the impingement plate and above the level of the drain means.
- 13. Apparatus for removing entrained liquid from a gas stream, the apparatus comprising a casing, having an inlet port and a gas outlet port, a housing having nonporous walls and supported within the casing, inlet means for directing an incoming gas stream from the inlet port into the housing, the housing containing a coalescing medium capable of coalescing entrained liquid from the gas stream and the housing being shaped and disposed so as to direct incoming gas substantially vertically downwardly through the coalescing medium, deflector means at the lower end of the housing for significantly changing the direction of gas flowing out of the housing to cause separation of the gas and the coalescing liquid, outlet means for directing gas to the outlet port and drain means whereby separated liquid may be drained from the casing.
