Structures for housing a filtration media for the removal and/or solidifying of synthetic ester-based fluids from liquids are provided. The structures disclosed include: a stormwater insert container for installation within a storm drain designed for intake of high volumes of water; an angling filter plug mounting structure and pre-filter basket for a flush installation on a planar floor, such that the filtration media rests beneath the floor and releases filtered liquids into a drainage area; a trench filtration assembly for installation into a trench below surface level, such that the unfiltered liquid passes through the trench and a trench box disposed within the trench filtration assembly prior to passing through the filtration media into a drainage area; and a liner box assembly for installation over an opening made in a non-permeable liner for purposes of pre-filtering contaminated liquids as it flows through the liner box and subsequently the filtration media.

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 disclosure relates to a filter apparatus for oil-water separation, and according to an embodiment of the present disclosure, when the filter apparatus for oil-water separation is mounted in a mixed fluid storage tank for storing a mixed fluid collected in seas or rivers in the event that an oil spill accident occurs, it is possible to drain off only water in the mixed fluid. In addition, it is possible to increase the storage efficiency of the mixed fluid storage tank by selectively draining and removing only water other than oil and impurities in the mixed fluid stored in the mixed fluid storage tank.

An oil/water separating device for removing oil-containing constituents from an oil/water mixture, including a main filter which is configured for separating oil-containing constituents from the oil/water mixture, where an oil/water mixture to be purified is supplied to the main filter from a top housing via a condensate line and is removed from the oil/water separating device after passing through the main filter, and the oil/water separating device is configured for supplying and removing these liquids in accordance with the hydrostatic principle, where the top housing is disposed above the main filter, wherein the distance between the top housing and the main filter is selected so as to result in a hydrostatic pressure on the main filter of at least 0.05 bars.

A system adapted to condition an initial water feed stream including a water treatment subsystem, wherein the water treatment subsystem includes a first oxygen removal unit including 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 hydrazine stream dissolved into the first deoxygenated water stream, a second oxygen removal unit including 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 hydrazine 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 crude oil desalter unit includes a settler, an inlet manifold fluidly coupled to the settler, and one or more inlet distributors extending from the inlet manifold to discharge a water-in-oil emulsion into the settler. Each inlet distributor includes a riser having a first end, a second end, and an inner flowpath extending between the first and second ends, wherein the riser is coupled to the inlet manifold at the first end, one or more outlet nozzles provided at the second end and in fluid communication with the inner flowpath, and a static mixer positioned within the inner flowpath and defining one or more helical pathways operable to induce rotational flow to a fluid flowing within the inner flowpath.
