  • Patent number: 8940067
    Abstract: A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

  • Patent number: 8080087
    Abstract: 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.

  • Publication number: 20080190288
    Abstract: A method and an equipment for improving global warming and air pollution are proposed, wherein hot exhaust gas generated by a thermal machine is injected into an exhaust boosting unit to be compressed and mixed with a liquid medium for atomization. Pollutants in the hot exhaust gas and heat generated due to combustion are adsorbed by the liquid medium. After the liquid medium passes a dust collecting unit, the pollutants adsorbed by the liquid medium will adhere to the dust collecting unit. Humid and hot clean air is extracted to the atmosphere, and rises to high altitudes and is cooled there. Water will drop to the ground in the form or rain or snow to cool the ground temperature and remove other pollutants in the air. Heat circulation and water circulation can be sped up to improve the situation of global warming and render more water resource to the Earth.

  • Publication number: 20080184888
    Abstract: The present invention relates to a method and an apparatus for forming fog by using at least one air stream connected to a tank where the air stream forms homogeneous droplets of a fluid, which droplets flow further in the air stream towards and through at least one outlet for forming a fog. The scope of the invention is to achieve a highly effective method and apparatus for generating fog with a long stand time having a small energy consumption. This can be achieved by a method and an apparatus as described in the beginning if the method further includes a first high pressure air stream that is lead to flow in a partly parallel direction to a liquid surface for forming at least one liquid sheet, which sheet brakes into droplets where a second air stream having a lower pressure transports the droplets through at least one outlet. Hereby, it is achieved that the liquid sheet moves forward continuously as it breaks up at the edges all the way around.
