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.
Glass doors are the integral part of architecture today. This is a fantastic choice for any kind of premises, from business centers through to apartments. One may think glass is not a strong material, but it is a misconception. Tempered glass manufacturers have long been offering the product that easily provides a good heat and noise insulation and boasts an outstanding strength and long life. Broad product range The broadest selection of glass doors, fittings and door cases enables to pick a door for any indoor scene. Quality High quality glass from world’s top manufacturers. Simplicity Leaf made of environmentally friendly and easily maintainable material. Safety Safety in use – tempered glass is very strong and does not form sharp splinters if broken. Long life Always the same appearance throughout the life.
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.
