The number of oil sands deposits is commensurate with the amount deposits of pure oil. Currently, it is not very profitable to extract oil from oil sands, since the cost price of oil extracted from oil sands is higher, than its cost in the extraction of pure oil from the field. Given the large number…
METHANOL OBTAINING IN THE FIELD OF NATURAL GAS PRODUCTION
Many components of the natural gas (methane, ethane, iso-butane, carbon oxides, nitrogen, hydrogen sulfide) in conjunction with water form gas hydrates. Hydrate formation favorably influenced by a combination of low temperature and high pressure. During gas production hydrates can be formed in the wellbores, industrial communications and natural gas pipelines. Sedimenting on the walls of…
New wear resistant and score resistant additives.
Wear resistant and score resistant additives are used to improve operation and to increase service life of the equipment in which units with different kinds of mechanical movements are used. These additives reduce wear of mechanical parts and improve the equipment service properties. They prevent seizing and grabbing of rubbing metal surfaces at load during…
A DEVICE FOR OBTAINING FINE-DISPERSED SILICIUM DIOXIDE
Abstract. A new burner of a slot type for obtaining fine-dispersed silicium dioxide by silicium tetrachloride high-temperature pyrolysis in water-air mixture is offered here. Urgency of such type burners use is considered. The sketch of the burner is given. The technique of fine-dispersed silicium dioxide obtaining by silicium tetrachloride pyrolysis using the slot type burner…
Packing of the carcass meat by polymer film obtained on the basis of new modified polyvinylacetate.
A new method of the carcass meat packing which makes if possible to improve it’s storage in transit and its keeping. The carcass meat packing is carried out in the following way. After the animals cutting(bull-calves, sheep, pigs, etc.) the warmed up peroxycontaining polyvinylacetate is applied on the surface of the carcass meat. After this…
Obtaining of copper laminated plastic on the basis of modified thermoreactive polystyrene
Key words: polystyrene, obtaining, copper, plastic, technology. Synopsis. A new production line of copper laminated plastic obtaining on the basis of modified thermoreactive polystyrene is suggested here. Utilization of modified thermoreactive polystyrene for copper laminated plastic manufacturing makes it possible to obtain cheap plastic with good physical, chemical and dielectric properties. Utilization of such…
Formic and acetic acids obtaining from ethane fraction.
Formic and acetic acid is a widely used commercial product and crude product for obtaining different substances. Total amount of these acids manufactured in the world makes millions of tons a year. Formic acid is the scarcest and the most expensive of them, the demand for it increases every year. There are different methods of…
OBTAINING OF FORMIC, ACETIC AND PROPIONIC ACIDS BY LIQUID PHASE OXIDATION OF LIGHT HYDROCARBON FRACTIONS
Abstract. Liquid phase oxidation of n-pentane without oxidate water-acid layer withdrawal from the oxidation zone, with oxidate water-acid layer withdrawal from the oxidation zone and by stages oxidation of the n-pentane with the oxidate water-acid layer withdrawal from the oxidation zone was studied at the temperature 165o C and pressure 5.06 MPa. It has…
