Patent ID: 8226742

Claim:
A liquid/gas separator device for separating liquid and gaseous phases of a fluid, the device comprising at least one vertically-disposed first reservoir of elongate shape of circular section, wherein: a) said first reservoir comprises a wall fitted with: a first bottom orifice at its bottom end, connected to an arrival pipe for said fluid, and including a pressure-lowering device; at least one first top orifice at its top end; and a plurality of first intermediate orifices; and b) said first reservoir is connected to a plurality of second reservoirs by a plurality of first transfer pipes, and to at least one second transfer pipe; said second reservoirs being likewise vertically-disposed, being elongate in shape and of circular section; c) each of said second reservoirs comprises: a second top orifice at its top end, connected to a common gas discharge pipe; and a second intermediate orifice disposed lower than said first intermediate orifice, to which it is connected by an inclined said first transfer pipe, and a second bottom orifice at its bottom end connected to a common degassed fluid discharge pipe including downstream an export pump suitable for drawing off said degassed fluid from the bottom ends of said second reservoirs; and d) said first top orifice of said first reservoir is connected via at least one second transfer pipe to at least one third intermediate orifice in at least one of said second reservoirs, said third intermediate orifice being situated above said second intermediate orifice in the same said second reservoir.
