One of the serious problems of natural environment protection during oil and gas production is liquidation ground by oil pollution. Oil and mineral oils disturbed ecological state of top-soils as a whole deformed biocoenosis structure. In results of damages (oil) pipe lines, oil-processing and petroleum distillating plants a great deal of oil and oil production comes in ground. Cleaning and reconstruction of in ecocatastrophe region realizes properly polluted ground impressments from pollution place with its posterior cleaning by chemical and biological methods or its, immediately contiguous to technological object also to environment air and burial on special firing range. Elimination the oil flood permits to greatly improve sanitary state not only on territories water. Oil hydrocarbons decomposition intensity and character in ground mainly defined by functional activity hydrocarbono-xidizing bacteria (HOB) capable to assimilate oil as a single carbon spring. Method biological or polluted burial on special firing range was not find wide application. Since the first method is virtual during of the ground pollution more than 5-10%. And second method is not widespread for the reason of loose huge number of grounds. During last years new compositional structure are developed by “Karvan L” company staff on the basis of surfactant species “LD500IF”. The reagent successfully passed work bench measurements on hydro-cyclone units and effectiveness of the feagent is 98 -99 % during expenditure norm 20-25 mg/l.
Crude oil flowing from wells contain fair amount (often 20-30%, sometimes up to 60-65%) of water with dissolved salts from basis point up to 1-2%. This significantly increases viscosity of crude oil, generates stable emulsion and makes the oil inadequate for refining and transportation. Water produced together with oil is usually in very unusual state, i.e. it is spread in oil in the form of droplets (emulsified form). Less the size of droplets, more stable the emulsion. One of the main reasons of emulsion stability is also the presence of resin, pyrobitumen, paraffin, and other oil admixtures like glycerine, microcrystal of paraffin, ceresin in crude oil. These substances generate quite firm and thick (protective films) on the surface of water and solid particles thus preventing merging of water drops and solid particles and their spontaneous segregation from oil. At present physical, thermal, physico-chemical, electrical and combined methods of oil emulsion breaking are used for oil dehydration and oil desalting. One of the widelyused and most effective methods is physicochemical combined method using chemical reagents demulsifiers. Demulsifiers are substances with high surface activity. They are concentrated in interfacial areas of oil emulsion, break protective films covering solid particles, water droplets and neutralise their electric charges. After this, small droplets will merge into bigger drops under the influence of mutual attraction, loosen and segregated from oil.Oil demulsifying is carried out in oil field and oil refinery plants. At present “KARVAN-L” company tries to provide integrated work cycle: – development production supply and implementation of produced demulsifiers together with consumer. Demulsifier Karvan-200 is designed for oil dehydration and desalting in gathering system and oil treatment plant. Reagent can also inhibit corrosion processes.Demulsifier Karvan-201 is designed for separation of both light and heavy crude emulsion. This reagent is the composition of macroglycols and nitrogen-bearing surfactants in organic solvent environment Demulsifier discharge per 1 ton crude is 10-60gr. Dosage depends on emulsion stability, treatment temperature, water separation period and desired depth of oil processing. Optimum dosage and demulsifier application process ensuring necessary results can only be defined as per test results carried out in practical use sites.
Lubricating properties of low sulfuric diesel fuel with K-Lube additive at device HFRR under method EN ISO 12156-1 (data of JSC “VNII NP” Russia): At present production of highquality diesel fuels is impossible without attaching of additives of various functionality as depressor, cetane increasing, antismoke, washing, anti-oxidizing, dispersive, corrosion inhibitors, anti-wear and many oth. At preparation of multifunctional packets of additives their compatibility are to be considered, as the various surfaceactive substances are able to influence upon functional properties of each other. At usage of “K-Lube” anti-wear additive in packets with additives of other functionality (cetane increasing, depressor-dispersive and other) no contradiction between them emerges. Just the opposite, the “K-Lube” additive operated better than its foreign analogues /proved by following testing hold by JSC “VNII NP” Russia/: Taking into consideration results of mentioned above the “K-Lube” additive possesses high protective effectiveness against weariness and we would to mention that usage of additive at enterprises and petroleum refineries enables to save financial assets. Besides high effectiveness of “K-Lube” additive regarding protection from fuel pumps differing from foreign analogues the product has low pour point without adding any dissolvents (no more than 45 degrees below zero), what facilitates transportation, storage and usage it in cold climatic conditions.

To this day, petroleum acids are still being studied by a number of researchers. Interest in the above class of organic compounds is not only attributed to practical perspective, but also to general humanitarian purposes. According to S. Nametkin, "... composition and structure of petroleum acids are closely related not only to the genesis of oil, but to the origin of life on Earth as well". Depending on their origin, oils may contain different amounts of naphthenic acids, extremely insignificant in all cases. Naphthenic acids are extracted from oils using alkali alcoholic solutions. Structure of naphthenic acids in any oil is the same and depends on the nature of oil. Among the oil produced worldwide, and particularly in the CIS region, Azerbaijan's oil features the highest content of petroleum acids. Oils of Bibi-Heybat, Romani, Binagadi, Balakhani, Sabunchi and other fields are rich in petroleum acids, which content in some crude oil grades reaches 1.5 – 2%. Due to the fact that acids extracted from naphthene-base crude of Baku oil fields have the same composition and physical-chemical properties as synthetic naphthenic acids, they are often referred to as natural naphthenic acids.
Naphthenic acids and their derivatives are widely used in more than 40 sectors of national economy. Naphthenic acids in a form of lead, manganese, zinc, ferrum, aluminium, chrome salts and in a form of other derivatives, are used in preparation of paint driers, varnishes, paints. Free naphthenic acids are used as a part of inks and improves their mobility. These acids are also used as thinner for aniline colorants, sleeper impregnation material preserving wood from rotting. Both free and derivative naphthenic acids have effective fungicidal, insecticidal, bactericidal and preservative parameters which are used in weed and pest control, for impregnation of wood, sail fabric, canvas, rope, tarpaulin, fishing gear and other materials regularly affected by moisture, bacteria, pest, etc. Lead, chrome, cobalt and manganese salts of naphthenic acids are used as antistatic, antideteriorant and antifoam additives for fuel, jet engine fuels and oils. Lubricating and emulsifying materials used for cooling of shearing machines, pasting, lubrication grease for high-pressure plants, demulsifiers brea-king petroleum and oily emulsions are based on naphthenic acids. Simple and compound ethers of naphthenic acids are used as plasticizers for production of polymeric materials, general rubber goods, polyvinylchloride plastic, hydraulic liquids, etc. Naphthenic acids are successfully used even at cleaning of rareearth elements, extragens of radioactive materials, catalysts, oxidation and oxonation processes, agricultural growthregulating substances, drying accelerators for glassreinforced polyesters, etc. In order to meet consumer needs for naphthenic acids, “KARVAN-L” company has developed technology and established commercial installations for output of high-purity acids.
