Abstract: An air-operated, submersible pump features a bladder-controlled inlet applicable to water pumping or fluid separation, including the recovery of viscous hydrocarbon products. The inlet area fluidly penetrates through a portion of the wall of the pump, and the bladder, disposed within the pump body, is supported in overlying registration therewith. A pressure-operated valve in fluid communication with the discharge port facilitates a refill mode of operation, wherein fluid surrounding the pump flows into the pump body through the inlet area, and a discharge mode of operation wherein the air inlet is pressurized, causing the bladder to inflate and seat against and seal off the inlet area, and fluid which flowed into the pump body to be discharged through the discharge port. In the preferred embodiment, the inlet area comprises a plurality of apertures formed through the wall of the pump body arranged as one or more linear arrays lengthwise along the pump.

Abstract: A foam trap or FOB for a gas propelled or mechanically pumped liquid dispensing system, having an upper ball stopper valve seat and gas vent port at the top and a lower ball stopper valve seat and liquid outlet port at the bottom, with two floating ball stoppers that are raised and lowered by the level of liquid unless locked into a seated position on a valve seat by pressure. Ball stoppers can be independently mechanically dislodged and constrained from reseating on either valve seat by externally accessible means. The interior geometry inhibits the ball stoppers from competing or blocking access to respective valve seats when liquid is falling or rising. The trap automatically shuts off outflow when liquid is depleted, permitting a container change, opening of the vent port, and purging of gas or air in the trap by refilling the trap with liquid before closing the vent port and reopening the outflow. The trap may be integrated into an automated container switching system for liquid dispensing systems.

Abstract: A gas-liquid separator system having a control system for controlling and maintaining a "normal" liquid level in the separator vessel. The system is capable of operating without the need for external power (e.g. electric, etc.) or the need for process gas to operate the valves. Also, the system is "fail safe" since the control valves for both the gas and liquid from the vessel will be in an open position if the control system fails. The system has control valve units on both the liquid and the gas outlets of the vessel. Each control valve unit is basically similar in constructon and has a valve element moveable between an open and a closed position by changes in differential pressure across a diaphram. The valve units are connected to the vessel and to each other to sense and response to any changes in the differential pressure between the top and the bottom of the vessel to open or close the respective valves to maintain or to reattain the normal level in the vessel.

Abstract: This invention is directed to a gas/liquid separation flow rate regulator, which effectively carries out gas/liquid separation by preventing an uncontrolled flow of sewage and facilitates control of liquid flow. To accomplish this objective, the outer shell of the gas/liquid separation flow rate regulator is cylindrical in shape with its inner periphery providing a cylindrical surface. An edge inclining unidirectly from one end to the other is formed at the upper edge of a partition plate for dividing the cylindrical shell into two chambers, and the lower end of this inclined edge is butted to the cylindrical surface of the cylindrical member so as to form an overflow weir. A return port is centrally located on the cylindrical member and is disposed on the opposite side surface of the cylindrical member facing the overflow weir.

Abstract: The present invention relates to a method for transferring a multiphase effluent whatever the value of its gas phase/liquid phase volumetric ratio GLR may be. The value of the GLR is determined by means of a measuring device D, before it reaches a separation tank, when the measured value of the GLR is greater than a boundary value, part of the gas phase is discharged through compression means in connection with the tank, as long as the level of the liquid-gas interface in the tank is below a threshold value.

Abstract: In an oilfield production system, a water driven jet pump is used to evacuate vapors from storage tanks to thereby recover the vapors and prevent emissions from passing to the atmosphere. The jet pump entrains the vapors in process water which is passed to a process separator already in the system. The gas is separated for recovery.

Abstract: Method and apparatus for controlling production of fluids from a well. A transfer vessel receives fluids produced from an oil and gas well which separate into liquid and gas phases in the vessel. A gas pipeline and a liquid pipeline are provided for transporting produced gas and liquid, respectively, from the vessel. A gas pressure control valve is provided in the gas pipeline. A bypass conduit having a bypass valve therein forms a shunt around the pressure control valve in the gas pipeline. In the event of an abnormal rise of liquid in the vessel, the bypass valve closes thereby increasing gas pressure in the vessel to a pressure sufficient to boost liquid therefrom into an emergency vessel drain.

Abstract: An apparatus for dispending a fluid free of included air bubbles, such as for example, an adhesive bead, includes sensing devices for detecting the presence of an included air bubble in the conduit leading from a source of the fluid to a discharge of a movable fluid dispenser. The sensing devices are connected to a motor which drives an arm on which the fluid dispenser is mounted. A first sensing device slows movement of the dispenser upon sensing an air bubble in the fluid and a second sensing device stops movement of the dispenser upon sensing an air bubble in the fluid. The movement of the dispenser is restarted after a predetermined time period sufficient to allow the air bubble to pass out of the dispenser discharge. The sensing devices advantageously use a light beam, such as infra-red light or laser, to detect the presence of the included air bubble.

Abstract: A process for performing a series of hydrodynamic functions or operation on a flow of fluids comprised of at least two phases includes the following steps: separating the fluid phases that comprise the initial flow; reducing the turbulence of the flows of each of the fluid phases which have been separated from each other; and recombining the fluid phases to form a new polyphasic flow with a predetermined structure.

Abstract: A decantation separation apparatus in which the material to be separated flows upwardly through an annular weir, and overflows to a decantation zone defined between the weir and a surrounding jacket. The separated liquid is withdrawn from the bottom of the decantation zone and the separated lighter phase from the top of the jacket, an obstacle for example in the form of a thin plate, being provided in the decantation zone above the liquid outlet for slowing the velocity of liquid within the decantation zone.

Abstract: A system to maintain the pressure within a pressurized container within dgn limits and to vent undesirable fluids to the ambient atmosphere. A float floats near the top of the container on the surface of oil supplied to the container by a pressure compensator and is seated to seal an opening as long as the oil level remains above a given level. Sufficient displacement of the oil by gases generated within the container will unseat the float to allow the venting of such gases to the ambient atmosphere. Another opening is also located in the top of the container and is sealed by a weighted lid. If the pressure in the container exceeds the local ambient atmospheric pressure by an amount that would otherwise rupture the container, the lid will be forced open to allow the relief of the excess pressure. When seated, another float seals an opening located in the bottom of the container. This float will float on atmospheric fluid which accumulates in the bottom of the container.
