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.

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.

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.

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

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.
