METHOD AND DEVICE FOR FILTRATION, DEGASSING, DEHYDRATION AND REMOVAL OF AGEING PRODUCTS IN PETROLEUM OILS Russian patent published in 1998 - IPC

FIELD: method and devices used in filtration, degassing, dehydration and removal of ageing products from petroleum oils and also in drying of transformers to remove moisture from insulation cellulose and for drying other oils and mixtures of oil products. SUBSTANCE: device 1 incorporates one or several boxes 2 interconnected by pipelines 12 accommodating barriers 3, 3a filled with adsorbers 4 for carrying out separate phases of the processes. Installed at inlets and outlets of body 2 are mechanical filters 5 of cast alloy. Inlet filter 5 is connected by means of pipeline 12 with pressure pump 8 connected with electric motor 7. Outlet filter 5 is connected by means of pipeline 12 with filter 5 of next box 2 of device 1 or directly to vessel 18 of user. In process, mixtures of oils are passed through mechanical filters 5 where particles of definite sizes 4×10^-3 are trapped and then through porous bulls of adsorbent 4 formed of aluminum silicates of crystalline structure with molecules of sodium and calcium for phase of degassing and dehydration, and aluminum oxides for phase of agglutination of ageing products, i.e. polar molecules. Regeneration process of all adsorbers 4 is carried out by their heating and subject to pressure variation. The device features small dimensions and weight with efficiency equalling that of the known apparatuses of the same purpose. EFFECT: higher efficiency. 17 cl, 10 dwg
