Established in the year 1996, Karvan-l Science Production Company deals in :
Azerbaijan has a variety of advantages to successfully develop its fruit and vegetable sector, including geographical location and favorable climate. Climatic conditions enable Azerbaijani growers to harvest their crops several times a year and significantly extend their fruit and vegetable season. In addition, Azerbaijan has an advantage of relatively low production costs again thanks to climatic conditions and rather low labor costs. Exported Azerbaijani vegetables, especially tomatoes and cucumbers, are well known in CIS countries and mostly appreciated for their taste and natural specifications. And our Company RGFruit LLC propose to you ORGANÄ°C FRESH vegetables and fruit s that were listed below : -onion -potato -cucumber -tomato -cauliflower -eggplant -garlic -cabbage -peas -apple -grape -cherry -carrot -lemon -nut -almond -walnut
Apples accustomed to the culture of Azerbaijan that every autumn Guba region celebrates an Apple Festival that attract many foreign tourists. Not only the trees, but the town also turns red and gold, as everything is painted in apple hues. The queen of all apples in Azerbaijan is undoubtedly Gizilahmadi . If you ask the Azerbaijanis to call their favorite apple, the first thing that will come to their minds would be, for sure, Gizilahmadi.
These requirement specifications apply to special-purpose distillate for AMG-10, RM and RMTs oils designed to obtain low pour point hydraulic oils of AMG-10, RM and RMTs oil grades. Example of product designation at ordering: “Special-purpose distillate for AMG-10, RM and RMTs oils acc. to requirement specifications TU 38.1011286-89”.
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.
Butyl, hexyls, octyl and glycolic ethers of ecologically clean naphthenic acids. Application: used for fluxing of general rubber goods, floor cloth (linoleum), dual vinyl plastics, varnishes and other polymer materials. They can be used as replacement of phthalate, phosphate plasticizer, castrol ethers. Presence of cyclic groups in ether molecules increases viscosity, improves their thermal and hydrolytic persistence. PLASTIFIERS NKL-1 Solvent ethers of naphthenic acid 1.

Naphtenic acids acids exudes from alkaline wastes after leaching distillates of diesel oil and kerosene naphtenic oils are effective stimulators plants growth. Oil growth substance is represent as water solution sodium salt of naphtenic acids 40%. (OGS) steep seeds before sowing use mixture with chemical fertilizers during vegetation for plant spraying in blooming period. Using the OGS grout concentration in water from 0, 001 to 0, 4 sharply to raise cotton productivity, winter wheat and other products. The OGS is supplied: 1. OGS increased growth (evolvement) of plants especially in initial stage and vegetation stage. Influence effect is depend on plant nature, soil nature, conditions and etc. 20-25% at a speed almost always rise, on the whole this indices are contained in interval from 20% ( it is was not lawyer) and it can exceed 100% over. 2. OGS increased crops productivity. In converting to productiveness from 1m2 in total due to increase speed and growth of yields quantity effect is very seemly. 40% 3. OGS sharply resistibility diseases and survival rate extreme conditions
Description IC series corrosion inhibitors a 98-100% active amido- or amino- imidazoline derived from naphthenic acids used to formulat corrosion inhibitors for use in drilling, production, transporting and refining of crude oil. Application Dissolved acid gases and biological deposits can cause severe corrosion to occur in oilfield water handling system. Corrosion by product such us iron sulfide, iron oxides and biological mass can cause plugging of downstream injection wells. Over a period of time, water system corrosion causes costly leaks and failures IC series corrosion inhibitors finds application for surfactants or corrosion preventives in all types of oil system. It can be used in concentrated form diluted for application. Advantages Concentrated corrosion inhibitor Effective in multiple applications Highly cationic amine compound Surfactant or corrosion preventive for oil systems Usage Optimum treatment concentration will vary depending on the specific application.
Desiccants, accelerators and hardeners are used in addition to main substances for production of varnish and painting products. Desiccants are combination of metals with organic acids. Carboxylic acids, i.e. naphthenic, aromatic tall oil fatty acids and octanoic acids are used for production of desiccants. KARVAN-L company uses ecologically clean natural petroleum distilled naphthenic acids (DNA), threshold limit value (TLV) of which is 40 times more than of actinic acids. KARVAN-L company produces the following desiccants-naphthenes: Dimethylation Naphthenate Mn Pb is prepared on the basis of special formula allowing to keep stable colour of desiccants. The following actual expendable norms passed the industrial testing on PF-060 and PF-053 varnish based enamels PF-127, PF-268, PF-115. The percentage ratio of chemical is as follows: Co 0.0125, Ca 0.0160, Zr 0.075, Zr 0.031, Pb 0.015, Mn 0.04. Metals with several common oxidation states as cobalt, calcium, zinc, zircon, manganese, lead are used in desiccant production. Each of these metals has different catalytic activity and has its own application, in particular: cobalt desiccant is most effective and can give good results, but usually it is used together with Mn, Ca, Pb. Calcium accelerates drying at low temperature, also eliminates turbidity and irregularity of film. Zinc decreases initial speed of surface drying, but accelerates overall drying. Zinc results in greater hardness of final film. Zircon is used in desiccants of titrimetric effect as replacement of lead and is less toxic, used in combination with Co, Mn, Zn. Manganese is a main desiccant after lead and cobalt and is the most important. It dries not only surface, but also depth of film. It is used together with Pb and Co, thus increasing hardness and transparency of the film. It is not used separately, because the film might become rough and friable.
