A technology that creates a dim surface and renders it grainy and non-transparent (an operation contrary to polishing). The dimming allows drawing a picture on a glass surface. The dimming is widely used in manufacture of glass and ceramic dishware, decoration elements, imitation jewelry, souvenirs, glass furniture and other glass items. Glass dimming methods can be categorized by five groups: dimming by mechanical treatment; chemical dimming; application of dimmed coating by firing; application of dim paint coats; other dimming methods.

Vinyl Windows and Doors An integral part of our company’s activity is the fabrication and installation of vinyl windows and doors. The doors can be of different models and types of opening. We fabricate and install windows and doors using the following profiles. The industry today is capable of producing vinyl, which is ideal for vitrification in all climatic conditions. The profiles for northern latitudes have thicker walls and partitions inside. The thicker is vinyl, the better its energy-saving ability. The number of chambers in such systems is three or more. The uniform width of vinyl frames enables to carry out glazing in conformance with windows and underline the design integrity. The door vinyl is decorated using the same materials and same technology as that for the windows. Which implies all items being of one color and style. The excellent noise insulation will allow you to enjoy a warm conversation with your friends. For now, the disturbing noise will not distract you from your pleasant home chores. Installing additional multifunctional glasses, you will enjoy a tender sunlight in the summertime and have a shield that reflects the heat back into your house in winter.
The all-glass enclosing structures of elevator shafts provide the main advantage of perceptible fragility and exquisiteness combined with guaranteed reliability and long life. The panoramic glazing of elevator shafts with architectural shutterproof glass (which is more commonly referred to as a panoramic elevator) has an advantage to conventional enclosed shafts. The main type of elevator shaft glazing Karvan-Glass apply is point glazing: glass is attached to the bearing structure made of stainless or construction steel using point fittings specially designed to compensate for dynamic loads that occur during operation of an elevator. In doing so, the maximum transparency is achieved. The versatility of elevator shaft designs using architectural safety steel is virtually unmatched among other materials. It ranges from full transparency which gives a panoramic view to passengers in an elevator through to modern photoprints on glass capable of embodying any designer’s concept. For instance, hidden glass fittings enable to create a solid structure that shares concept with the decorative glazing of walls.

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.
Translucent structures represent a convenient, functional and stylish decoration of various types of buildings and facilities. They look pretty well with business centers, shopping malls, and administrative buildings. They boast a light and elegant appearance but still maintain a serious yet fine exterior. The translucent structures enable to save on artificial lighting as they let in more sunlight. These structures are built using highest quality glass panes, which renders them, even greater advantages, namely noise and heat insulation as well as power saving ability. Translucent structures are about filling both horizontal and vertical planes of a building or facility with glass panes above an aluminum façade. Glass facades from our company represent minimum costs with always-high quality and versatility of designer solutions, which is a decisive factor for most satisfied customers who have already chosen Karvan-Glass.

Petroleum refining is characterized by the largest amount of systems exposed to corrosion compared to any other sector of the oil industry. Corrosion problems occur everywhere, from the points of raw materials delivery up to removal and transportation of the refined products. Corrosion control measures shall be taken at crude oil distillation plants and units for alkali treatment of oil, gas plants, reformer and cracking units, straight run deisobutanizers, units for adsorption of hydrogen sulphide from aqueous solutions, furfural treatment units etc. Liquid composition may vary depending on a particular stage of the oil refining cycle – from sulphurous, acid oil-water mixtures fed to refineries to final products (e.g., gasoline) with negligible water content. It is hardly possible to use any “universal” corrosion inhibitor due to the variety of process mechanisms that may cause intense corrosion of equipment used in the oil sector. The need to ensure property package determining processability and compatibility of the inhibitor with corrosion medium components necessitates development of an inhibitor that would be functional in different corrosive conditions. Oilfield water containing large amounts of chloride ions, oxygen, carbon dioxide and hydrogen causes and promotes further development of local electrochemical processes, which represent the most dangerous type of corrosion and failure of metal. Oilfield practice shows that the most dangerous local corrosion damages also occur in the presence of microorganisms. In order to protect oil equipment against chemical and bacterial corrosion, Karvan-L company designed efficient and cost-effective water-soluble and oil-soluble corrosion inhibitors. Corrosion inhibitors are nitrogen-containing surfactants, produced based on natural acids with addition of film-forming admixtures and biocides.
