摘要： A submersible reverse osmosis desalination apparatus and method employs airlift to remove desalinated water from the apparatus via as annular flow regime over a substantial portion of the product water discharge conduit. Use of a high air fraction for airlift operation and an annular flow regime significantly lowers the weight of the product water column, as well as the backpressure on the downstream side of the osmotic membranes and at the bottom of the discharge water conduit. This permits deployment of the apparatus at reduced depths and in many eases closer to shore. In preferred embodiments the apparatus relies wholly upon hydrostatic pressure to drive seawater through the osmotic membranes, and continuously desalinates seawater and delivers pure water to the discharge water conduit without using any submerged moving parts subject to wear or breakage.

摘要： In a bubble lift system, a pressurized chamber at an upper end portion of a riser pipe applies a pressure to an upper portion inside the riser pipe to suppress an increase in the volume ratio of bubbles to a fluid mixture rising inside the riser pipe in a shallow water region. The upper end of the riser pipe is not opened to the atmosphere but is inserted into the pressurized chamber under a high pressure to thereby prevent expansion of the bubbles and gas. In addition, a deaerator for discharging bubbles separated by a centrifugal force is also provided in a middle portion of the riser pipe in a shallow water region to distribute the bubbles more evenly inside the whole riser pipe. The bubble lift system and a bubble lift method thus provided are efficient and employable even in a deep water region.

摘要： An airlift pump comprising a hollow, cylindrical main body having an injection hole near the bottom end, a channel routed in the outside surface of the main body and extending continuously from the injection hole to the top end, and an air tube seated in the channel and bonded to the main body. The air tube comprises an injection end having an elbow forming an injection angle such that the air is injection into the main body in a downward direction toward the bottom end. The air tube further comprises a receiving end extending past the top end of the main body and connecting to air supply tubing. The pump has a restricted lateral width enabling the pump to fit inside the narrow monitoring wells typical in the groundwater monitoring industry.

摘要： Well pumping of fluids having low hydrostatic pressure is provided through a combination of jet pumping and gas assisted lifting. A jet pump is located in a borehole in a producing zone of a well, and a source of gas is introduced into the fluid returning from the production location. The gas may be injected into the fluid used to operate the jet pump, such that the gas remains compressed until exiting the jet pump, and then provides assistance in lifting the returning fluid.

摘要： The invention comprises gas lift apparatus including a generally tubular mandrel defining a main longitudinal bore therethrough and including pocket walls defining a longitudinally extending pocket laterally offset from the main bore and generally divided therefrom. The pocket has an open upper end for insertion of a gas lift valve. The pocket walls further have ports extending laterally therethrough on both sides of pocket, i.e. between the pocket and the main bore of the mandrel and between the pocket and the exterior of the mandrel. On one side of the pocket there are at least two such ports longitudinally spaced from each other, and on the other side of the pocket there is at least one port disposed longitudinally between the aforementioned pair of ports. The invention further comprises a gas lift valve adapted to be received in the pocket, and when so received, operable to permit communication between the port or ports on one side of the pocket and the port or ports on the other side of the pocket.
