A device for gas-liquid separation, intended to equip three-phase fluidized bed reactors such as those used in the H-oil process. The device has a succession of two bends situated in different planes, which device accomplishes excellent separation of the gas and of the liquid.

A fuel filter has a separating device separating, from a medium flow comprising a first medium and a second medium, the first medium as a separated first medium contaminated with the second medium. The fuel filter has a cleaning device receiving a proportion of the second medium contained in the separated first medium. The cleaning device is arranged upstream of a discharge opening for discharging the first medium from the fuel filter. The cleaning device is provided with an absorbent/adsorbent cleaning material. The cleaning material contains or is made of an organoclay as an active component. The organoclay is a bulk material, wherein at least 50 wt. % of the organoclay has an average particle diameter of greater than 50 Φm and smaller than 1,000 Φm.

A pneumatic system installed on a vehicle and method of using the system to preheat compressor oil and/or components of the system to promote operation in cold weather conditions. The pneumatic system includes a compressor that generates compressed air in which oil is entrained, a separation tank that separates the oil from the air prior to the oil being returned to the compressor, and a heating element located within the separation tank and contacting the oil within the separation tank. Engine coolant of an engine cooling system of the vehicle flows through the heating element and the heating element transferring heat from the engine coolant to the oil within the separation tank to increase the temperature of the oil.

A system adapted to condition an initial water feed stream, comprising a water treatment subsystem comprising a first oxygen removal unit comprising a membrane filter, wherein the initial water feed stream flows through the membrane filter and the first oxygen removal unit is adapted to treat the initial water feed stream to remove a first portion of the dissolved oxygen to form a first deoxygenated water stream, a hydrogen stream dissolved into the first deoxygenated water stream, a second oxygen removal unit comprising a vessel filled with a palladium-doped resin, wherein the second oxygen removal unit is adapted to treat the first deoxygenated water stream including the hydrogen stream dissolved therein to catalytically remove a second portion of the dissolved oxygen to form a second deoxygenated water stream, and an oxygen scavenger feeder adapted to blend a chemical scavenger and the second deoxygenated water stream.

A system adapted to condition an initial water feed stream into a treated water stream, the initial water feed stream including at least one of: a sulfate; a hardness; a dissolved solid; and, an oxygen. The system including a sulfate and hardness removal membrane unit adapted to treat the initial water feed stream to remove the sulfate and the hardness, a high pressure reverse osmosis unit adapted to treat the initial water feed stream to remove the dissolved solids, a first oxygen removal unit adapted to treat the initial water feed stream to remove the oxygen, and a second oxygen removal unit adapted to treat the initial water feed stream to catalytically remove the oxygen.

A membrane comprising a crystalline material deposited on a porous support. The crystalline material is made of tectosilicate with a portion of the Si atoms substituted with metal atoms. The membrane is useful in the separation of oil and water.

The present invention provides a drain apparatus (200) for use in a subsea pipeline to remove liquid from a multiphase flow in the subsea pipeline. The drain apparatus comprises a first channel (20) for carrying a multiphase flow comprising liquid and gas phases; and liquid extraction means (11, 12, 14, 18) for extracting the liquid phase from the multiphase flow in the first channel (20). The internal diameter of the first channel (20) is substantially the same as an internal diameter of a subsea pipe arranged to carry the multiphase flow in the subsea pipeline, such that a pig travelling along the subsea pipe can pass through the first channel (20). The present invention also provides a subsea pipeline comprising a subsea pipe for transporting a multiphase flow subsea; and at least one drain. The at least one drain is disposed partway along a gradient in the subsea pipe to reduce liquid holdup.

The present invention provides method for separating contaminants from a liquid mixture comprising the steps of a) providing a feed of said liquid mixture to be purified, b) adding a separation aid to the liquid mixture to be purified, wherein said separation aid is capable of binding said contaminants and c) supplying a flow of compressed air into said feed after step b) has been performed to provide a feed comprising air. The method further comprises steps d) removing air from said feed comprising air to provide a deaerated feed; and e) supplying said deaerated feed to a separator, and f) separating a phase comprising contaminants and said separation aid from said liquid mixture in said separator, wherein the separation aid added in step b) is insoluble in said liquid mixture at the separation conditions in step f). The present invention further provides a system for separating contaminants from a liquid mixture.

A phase separation device having a device housing (2) accommodating at least one coalescer element (42), wherein said device housing (2) has an inlet (38) for the supply of an emulsion, which flows through the respective coalescer element (42) for separation into at least two of its constituents; an outlet (46) for a separated constituent; and a further outlet (22, 64) for a further separated constituent having a lower density than the one constituent and floating on the latter.
