I am a professional in chemical industry with 20 years of industry experience developing complex chemical processes of organic chemistry.
I have designed a formula with which to develop products for the treatment of boiler water vapor; descaling, inhibitors corrrocion and treatments for cooling towers.
My formula have been duly verified and have a high efficiency, which will give an excellent performance, with better compared with the competition thus obtaining a 100% biodegradable.
Chemical offer advice, specialized formulations, my services as a chemist, training both workers, investor or profesional, in the form of rent or sale.
The object of this biodegradable Formula is to prepare multicomponent liquid. Anticrustante, avoiding corrotion and prevents life of pipes. This way we avoid the accumulation of sludge and sediments achieving a perfect purge. An appropriate and well alkalinity. This also acts as a slow descaling.
The importance of water treatment has on the life, efficiency and safety in the operation of industrial boilers; They will also deliver recommendations for the definition of water treatment programs and explains how to detect the most common problems.
Water treatment of a steam boiler or hot water is essential to ensure a long life free of operational problems, major repairs and accidents.
The main objective of water treatment is to prevent corrosion and fouling problems, ensuring quality water supply and the water in the boiler.
The quality assurance feedwater and boiler water is achieved by fulfilling the requirements of the rules, which define the recommended parameters involved in water treatment limits.
2. Water sources
Water sources correspond to all that water, which has not received any treatment and therefore contain impurities, acquired during the cycle which have been subjected, preventing their direct use in a boiler.
As the water flows over the surface of the land or percolates through the layers thereof, or dissolving impurities continuous trapping soil or minerals being experienced. This is how seemingly clear water.
Water, can have a high content of dissolved solids.
Impurities found most frequently in water sources include the following suspended solids, immiscible liquids with water (eg. Oil), colorants, bacteria and other microorganisms, semi-colloidal substances, dissolved gases, dissolved mineral salts ( cations, anions and silica).
Then the problems associated with water treatment, most frequently found in the boilers are described.
The main sources of corrosion in boilers are oxygen corrosion or "Pitting" Corrosion and Caustic.
Then described in consisting each of these types of corrosion, the factors that favor is that looks and how can be prevented
Oxygen corrosion is the reaction of oxygen dissolved in the water with the metallic components of the boiler (in contact with water), causing their dissolution or conversion into insoluble oxides.
The results of this type of corrosion are tubers black color, which are formed on the area of corrosion.
Since oxygen corrosion is caused by the action of oxygen dissolved in the water, this can also occur when the boiler is out of service and enter air (oxygen). Preventing oxygen corrosion is achieved by adequate feedwater degassing and maintaining an excess of oxygen scavengers in boiler water.
Caustic corrosion occurs by a local overconcentration in areas of high thermal loads (hearth, rear camera, etc.) alkaline salts such as caustic soda.
This type of corrosion is manifested in the form of deep cavities, similar to "pitting" of oxygen, oxide filled black color, present only in areas of high heat release (fire, backplate and rear camera) of a boiler.
Caustic corrosion can be prevented by maintaining alkalinity, and pH of free OH boiler water within the recommended limits in paragraph 4.
The condensate return lines, logically not part of a boiler, however, has corrosion effects on boilers and can be prevented by treating water.
Corrosion lines condensate return has effects on boiler as oxides (hematite) produced are entrained into the boiler with the feedwater. Every boiler water whose side has a reddish color presents problems of corrosion in the condensate return lines.
Corrosion in the condensate return lines occurs by the action of carbonic acid in these forms.
Preventing corrosion in the condensate return lines, it can be achieved by neutralizing amines which neutralize the action of carbonic acid and amine protecting filmic lines.
These amines are volatile so to be dosed to the water supply lines, they are entrained by the steam produced in the boiler.
Fouling deposits correspond to carbonates and silicates of calcium and magnesium, formed due to excessive concentration of these components in the feedwater and / or blowdown of insufficient regimes.
In the figure it is possible to observe the upper run of the smoke tubes of a boiler inlaid with over 8 mm thickness.
The action of dispersants, chemical washes or expansion and contraction of a boiler can drop the scale, so must be eliminated in a very encrusted boiler to prevent its accumulation in the bottom of the pressure, as shown in the figure.
In the event that these inlays are not removed, you run the risk of embancar the boiler and obstruct the blowdown line, so that the problem may become even more serious.
The presence of scale in a boiler is particularly serious because of its low thermal conductivity acts as a thermal insulator, causing problems cooling of metal surfaces and can eventually cause damage sobecalentamiento.
In the figure the effect of the thickness of the layer of scale of a boiler shown in metal temperature. With increasing the thickness of the layer of scale, for the same heat flux, the metal temperature increases.
Accumulation background body boiler fouling pressure.
Scale formation in a boiler can be prevented, satisfy the requirements of feed water and boiler water included in point 4, treating the feedwater and maintaining adequate purge regimes.
The object of the present invention is the preparation of a liquid policomponente antifouling which eliminates corrosion and prevents wear of the pipes, avoiding the accumulation of sludge and sediment achieving a perfect purge, providing an appropriate alkalinity, and acts as a slow descaling.
The present invention is a product that is added to the boiler water and comprises UN5 antifouling policomponente containing sequestering calcium and magnesium, and it is corrosive, have products that increase the pH, and contains oxygen scavengers eliminating corrosion piting (corrosion process). Prevents wear and corrosion of pipes caused by the presence of oxygen dissolved in water, prevents the accumulation of sediments and sludge, achieving an effective purge and provides an appropriate alkalinity controlling corrosion caused by acids. The product has been formulated to also act as slow descaling.
This invention relates to a product intended as possible slow corrosion piting, which is localized and accelerated from a metal as a result of film rupture oxygen dissolution in boilers. The piting is considered as a process of autocatalytic nature, so that once drilling begins to grow a number of conditions that promote growth of said perforations are developed. BACKGROUND OF THE INVENTION
Assuming that the current problem existing in the treatment of boiler water, we can say that water in its purest form, is a tasteless, colorless and odorless liquid, and because of its abundance as a convenient temperatures , can be converted into steam, it is an ideal place for force generation means and for
also because water is the universal solvent, it dissolves many substances, so the water completely
there is rarely pure as they always contain gases and solids in suspension.
The main gaseous impurities are carbon dioxide and oxygen found in large quantities in the air.
The main impurity solid: calcium bicarbonate, magnesium carbonate, calcium sulfate, magnesium sulfate, silica, sodium chloride, iron, aluminum etc. All these impurities are produced in the boiler producing scaling, corrosion, clogging, foams, heat losses, etc. tube breaks
The inlays are hard crusts which adhere to the walls and boiler tubes. These inlays are
produced by the presence of solids are dissolved in water, that with increasing temperature, the 30 solids, lose solubility precipitating on the walls and tubes of the boilers.
Corrosion is the process of wear material which teams are built. This phenomenon occurs especially by the process of galvanic cell, that is, by the formation of acid (dioxides carbon dissolved in the water to temperature change carbonic acid is formed) or by pitting the latter by the presence of oxygen, with the most common.
As for sludge, all the impurities that water has to go evaporating becomes more concentrated inside the boiler reaching precipitate, forming a hard mud, which together with inlays, manage to avoid a transfer of ideal heat and over time, rendering inoperative or dangerous boilers.
In short the current problems in such treatment is a treatment polyfunctional attack together all these problems effectively is not achieved.
