An oil dehydrator, comprising; a vacuum chamber, a vacuum pump arranged at an upper end region of the vacuum chamber for establishing a negative pressure within the vacuum chamber and for fluid transportation of water and air out from the vacuum chamber through an outlet opening, and a pipe for fluid transportation of oil into and/or out from the vacuum chamber, where the pipe is connected to a lower end region of the vacuum chamber, wherein the vacuum chamber at the lower end region has at least one flow channel fluidly connecting the vacuum chamber and the pipe, wherein an orifice check valve is arranged between the vacuum chamber and the pipe for controlling the flow of oil into and out from the vacuum chamber through the at least one flow channel.

A system to treat and desalinate wastewater using a low energy ejector desalination system (LEEDS), which employs a static liquid-gas ejector and maximum heat integration in the water treatment system.

Method and plant for fluid purification by distillation comprising a reservoir (1) with a fluid containing diluted solids provided with an impurities filter on its outlet (2); a pump (3) connected to the reservoir outlet (1) and set up to increase the fluid containing solids pressure and temperature; and a heat area (4) for the fluid containing solids comprising a plurality of ducts contacting with a heat transfer fluid; and, furthermore, comprising a convergent-divergent nozzle (5) connected to the heat area outlet (4) and set to increase the biphasic liquid-vapor fluid speed so the diluted solids contained in the fluid already heated settle in a solids reservoir (6), whereas the fluid passes to a condenser (7) and then to a purified fluid reservoir (8) already in liquid state.
