A filtration vessel is shown for use with a rotary screw compressor which receives a compressed liquid/gas mixture from the compressor. The vessel utilizes a first stage vortex knockout region to remove bulk liquids through a circular motion which imposes centrifugal forces on the gas and liquid mixture. A coalescer region located above the vortex knockout region receives the relatively lighter fluids and separates any remaining entrained liquids from the fluids. The discharge from the filtration unit is an essentially liquid free compressed gas. The liquid discharge, in the case of lube oil can be recirculated to the compressor for another cycle.

A fuel filter system characterized by a simple design provided with a coalescer element (20) disposed in the immediate fuel inlet region for improving the elimination of water droplets. The coalescer element includes an upper end plate (26) that extends to the inner wall of the housing (10), thereby sealing the coalescer element as well as the inlet region and the outer unfiltered fluid region. The coalescer element (20) and the particle filter (19) are arranged on a common separating element (25), which rests against the discharge tube (17) located in the center of the fuel filter via a profiled seal. The end plate of the coalescer element can be produced with the profiled elastomeric seal molded thereon by two-component injection molding or by overmolding.

A filter coalescer element for oil based industrial fuels includes a rigid, porous support tube, and a hydrophobic drainage layer covering the outer surface of the same. A single phase, dual function combination water coalescer and particle filter pleat block is positioned in the support tube, and is formed from a multilayer material having a first porous support layer, a synthetic microfiber layer, a synthetic fiber media layer and a second porous support layer. As the fluid passes through the pleat block, solid particles are physically filtered therefrom, and water is coalesced into droplets which pass from the pleats directly through the support tube and directly into the drainage layer, where the droplets grow into a size sufficient that they fall under gravity to the bottom of the element for collection.

A raster unit generates graphic data for specific regions of a display device by processing each graphics primitive in a sequence of graphics primitives. A tile coalescer within the raster unit receives graphic data based on the sequence of graphics primitives processed by the raster unit. The tile coalescer collects graphic data for each region of the display device into a different bin before shading and then outputs each bin separately.

The invention discloses a novel high-efficiency crude oil electric dehydration and desalination method and novel high-efficiency crude oil electric dehydration and desalination equipment, which can be used for dehydrating and desalinating crude oil emulsion in oil refineries. The processing equipment mainly comprises an inlet component, a tank and an electrostatic precoalescer; when a high-voltage explosion-proof transformer outside the device applies high-voltage alternating current to the crude oil emulsion in a corrugated hollow tube through metal electrode plates by a high-voltage insulating wire, a non-uniform alternating current field is produced between the electrode plates to cause dielectrophoresis coalescence of dispersed phase water particles; the flow state of the crude oil emulsion in the hollow tube is turbulent flow, and the turbulent flow increases the collision probability of the dispersed phase water particles in the crude oil emulsion and obviously shortens hydraulic retention time; and a flowing passage in the electrostatic precoalescer can be designed to be corrugated circular or wavelike quasi-rectangular. By using the method and the equipment, the dispersed phase water particles subjected to electrostatic precoalescence can obviously reduce subsequent gravity settling time and improve the processing efficiency; and after the crude oil emulsion enters the tank from the inlet component at the left end, the crude oil emulsion flows along the horizontal direction and can reduce the power consumption of an inlet.

A method of drying liquid and gaseous hydrocarbons by contacting a feed stream of the hydrocarbon with an aqueous solution of a salt drying agent prior to passing the stream through a salt dryer to remove part of the water in the stream. The aqueous solution of the salt drying agent is generated in the salt dryer when the partly dried stream comes into contact with the drying salt and forms the solution. The solution is circulated in a loop from the salt dryer to the incoming feed and then through a liquid/liquid coalescer which removes a portion of the water together with dissolved salt from the mixture before the mixture is passed on to the salt dryer where further removal of water occurs. The salt dryer is off-loaded by a substantial factor by the initial partial dehydration and does not require to remove such a large amount of water; the salt consumption is therefore reduced in proportion to the amount of water removed in the treatment steps which precede the dryer.
