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.

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.
It often happens that people confuse glass panes and vinyl windows. These are not synonyms, however. A glass pane is a part and nearly crucial part of a window structure. This is a translucent structure consisting of two or more glasses that are fixed (glued) together along the outline using spacing bars and sealant compounds. Main functions of a glass pane: natural lighting, thermal and noise insulation. Glass panes are categorized by manufacturing process: standard, where molecular sieve is poured into a metal or vinyl spacer, after which the glued glass sheets are plastered along the edge with silicon, isomelt, polysulfide or polyurethane sealant compound, thus providing the secondary sealing. Warm edge technology-based manufacture This is a new and promising technology. It differs from the standard technology in that instead of several production steps as in the case with glass pane it involves only two (flexible spacer application, pressing), thus greatly saving time and cost. Such glass pane is warmer than that manufactured using a standard technology. As defined in GOST 24866, glass pane are categorized as follows: by number of chambers. A space between each two glass sheets is called a chamber. Glass panes can be single-chamber (two glass sheets), double-chamber (three glass sheets) and so on. by width The glass pane width is the full width considering its glass and air part. Glass panes can be 14, 16, 18, 20, 22, 24, 28, 32, 36, 40, 42, 44 etc. mm By glass type: regular energy-efficient glass with low-emission coating (hard or soft, also known as - or I-type) noise-resistant triplex sun-screening tinted or film-coated glass shutterproof glass with a high protection class.
