Increase of ecological requirements to emissions of car engines and toughening of operation terms of modern combustion engines require usage of various additives to petrols in larger scales. Restrictions on sulfur content until 0,001 and 0,005% were set forth in Sweden for the 1st time in 1991, and until present they are the strictest one. In 1993 the restriction of sulfur in fuel till 0,05 was applied in USA, in 1994 – in Canada, in 1997 – in Japan. Since 2000 diesel fuel with sulfur content no more than 0,035% is applied. Supposedly, since 2005 sulfur content in fuel wont exceed 0,005%. Along with decrease of harmful emission in exit gases, application of ecologically pure diesel fuels entailed a number of problems: breakdown of fuel pumps, due to decrease of lubricating ability of diesel fuels and .increase of corrosion activity, related with removal of surfaceactive substances able to form protective film. In 2005-2010 stiffer norms on sulfur content are proposed: up to 10 ppm and polycyclic aromatic carbohydrates up to 2%. Starting from 2000, the indicator of lubricating properties of diesel fuels under ISO 12156-1 at HFRR device is included in European standard regarding the diesel fuel EN 590, basing on it the norm is set forth: diameter of wear scar is no more 460 mkm. Requirements to quality of diesel fuels under EN 590
Stable development of our country directly depends on competitive ability of domestic products, which, in its turn, depends on quality control (i.e. level of testing labs). Specificity of analytic labs requires special system of their competitiveness recognition. Their accreditation synthesizes general approaches to accreditation of testing labs and peculiarities of analytic operations. In relation with it the actual is application of international standards: 1.management system of lab quality and application of standards 2. Lab-information systems in quality management system 3. Modern analytic equipment and automatization of separate processes in lab activity. Karvan-L” company lab repeatedly passed accreditation in Azerbaijan State Committee of Attestation, accreditation certificate No. AZ 031.01.11.02.49.07 dated on 14.03.2007. Lab possesses modern equipment for conduction of wide range of analysis in oil chemistry and oil-chemical and organic synthesis, as well as of initial products of synthesis. Particularly, Karvan-L” company lab is fitted by up-to-date machinery for quality control of oily acids, and initial raw material for production of paintwork materials based on pentophtalein, acryl, vinilcetate, polyurethane and etc. film-making clay compositions, driers, initial components of alkyds, acryl, and polyurethane enamels and emulsions, water and oil soluble inhibitors of corrosion, deemulsifiers, additions to oils, oil solvents, aromatic carbohydrates, processed oils and paints, plant oils, sewage of analogical production.
o 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.
Purpose: According to GOST 24211-91 ?«Additives for concrete?» softener is applied to regulation plasticity of concrete and concern I groups of a class. Action: Plasticity mark P1 up to P5 increases sdditives of softener. After 28 days of drying hardness raises on 30-60% and norms of charge of cement on 1 m3 is reduced on 60-100 kg thus it intended for improvement of otheres building ??“ technical qualities of concrete. Quality parameters are resulted below: Color – colorless Density – 1,16 gr/m3 pH – 8-9 In the additive there is no chlorine.Norms of the charge calculated on the dry rest weight of cement of 0,4-1,0%. Guarantee: Guarantee for 6 month. Packaging on metal and plastic drums, transported in 250 kg metal containers.
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.
