CONCLUSION
On the basis of the studied laws of the states of a number hydrocarbon and mineral ore dispersed systems, current scientific and technical tasks in the field of resource-saving in industrial sectors such as oil and gas, and metallurgy were solved. The main scientific and practical results obtained at the fulfillment of the dissertation work are following: 1) The regularities of oil and gas dispersions regulation were determined: - Kinetics of adsorption of hydrocarbon vapors on solid sorbents; - Absorption kinetics of hydrocarbon vapor by liquid absorbents; - Fuel evaporation kinetics at the interface: liquid-vapor; 2) On the basis of the developed principles of vaporization control in the dispersed fuel systems, technological solutions were proposed: - Adsorption vapor recovery fuels on novel adsorbents (active carbons, zeolites NaX, NaA, CaX, with the balance making of the vapor fuels recuperation, construction of adsorption isotherms, development domestic «Activated KAU-M carbon TSh 88.16-31: 2007» and the adsorption recovery units based on it); - absorption vapor recovery by absorbent (diesel fuel, due to the «big breath» storage tank when filling in the «intermediate» tank fuel distributive system); - fuel saving during the storage owing to reducing their evaporation, as well as owing to the area decreasing of the phase interface: the liquid-vapor (with the 72 effect of 85-95%, by reducing the GS of reservoir and overlapping by 98% of fuel surface mirror by pontoon. Alternative for it structural material is polyethylene terephthalate, float shapes are cone with firefighting function). 3) Number of surfactants series AT and PT were developed based on local anthropogenic raw materials. Their colloid-chemical and performance properties were studied as foaming agents in devices extinguishing of cone-floats pontoons tanks storage of fuels and flotation benefication of Cu-Mo sulfide ores from Kalmakyr at JSC «Almalyk MMC». 4) HMC polymer SC has been developed on the basis of local anthropogenic raw materials representative itself a hydrolysis product of waste production polyacryl nitrile fiber for the resource saving production of candle end of molybdenum middling at SPRM CSP of JSC «Almalyk MMC», as the novel component of the charge granulation of Mo concentrate. Its new composition (wt.%): Mo concentrate 97.3-97.0, kaolin 2, water soluble SC polymer 0.7-1.0. When necessary, kaolin was less replaced by the bentonite and SC polymer on CMC or PVA, to adjust the concentration of substitutes. Hydrophilic, strength, structural, physico-chemical and technological properties of the charge Mo concentrate based on binders: kaolin and organic polymers derived from them granules and candle end were compared. Technology of candle end processing of molybdenum middling with the new charge is not differenced from existing technology, from traditional composition of mixture: 8-10% kaolin and the rest is Mo concentrate. However, it facilitates the extraction of Re, Mo out of candle by sublimate condensation and ammonia leaching, respectively, as well as the extraction of Au and Ag out of ammonia leaching cake of Mo by cyanide leaching.
