Steam boilers are mainly made of carbon steels, and the internal surface of these metals that are in contact with water must be free of deposits. Deposits have a lower thermal conductivity than metals, which causes the temperature of the metal to rise on the combustion wall side. Therefore, more fuel is needed to produce steam. Therefore, there is a need to control and wash these deposits inside the steam boiler.

Metals are subject to corrosion in most chemical environments, for example, metals corrode in contact with water, moisture, acids, bases, salts, oils, gaseous substances and other chemicals. In general, minerals are more corrosive than organic substances. For example, corrosion in the oil, gas and petrochemical industries is often caused by the effects of minerals such as chlorine, sulfur, etc., rather than by organic substances such as oil, petroleum and diesel.

Failure to pay attention to corrosion problems in any industrial and manufacturing unit results in hidden costs that are impossible to avoid. Economic considerations are essential in each of the corrosion control methods. Of course, there is no need to choose the most expensive corrosion control methods, because the costs incurred may not be economically justified and waste capital.

Corrosion is often not uniform along the length of a member and is usually confined to the middle or ends of the member. In the case of piles, corrosion may be severe above the waterline and mild or absent below. This area of ​​maximum corrosion is often further away from the sections of maximum anchorage and shear forces, but rebar may be uniform throughout the member.

Corrosion inhibitors are substances that, when added in small amounts to a corrosive environment, slow down the rate of corrosion. In fact, an inhibitor can be considered a retarding catalyst. There are many inhibitors available with different compositions.

Corrosion inhibitors are additives that control corrosion by altering the metal surface, the environment, or both. Their mode of action is to alter the anodic, cathodic, or both reactions. There are many corrosion inhibitors available with different compositions. Most of these materials have been discovered and refined through experimental testing, and many of them are sold under trade names and their chemical composition is kept secret.

Corrosion in steam generation systems causes many problems in refineries, gas plants and petrochemical plants. Corrosion in boilers is a function of the concentration of oxygen, carbon dioxide and ammonia and the way these species are controlled, and in some cases is caused by the presence of hydroxide and chloride anions or high concentrations of chelating chemicals in the boiler water.

In order to compare DM and mitreh solution, it should be kept in mind that three different substances should be used for sediment removal, sediment prevention, and corrosion prevention, and in this regard, usually materials such as acids for sediment removal, DM for sediment removal, and in some cases Materials are also used to remove oxygen from water.

Mitreh's antifreeze and antifreeze has a great performance in terms of heat transfer due to its high heat capacity, and it is considered the most economical and available fluid for this purpose. Water alone has a relatively low boiling point, which means that it boils at a high temperature, and it also has a high freezing point, which means that it freezes quickly in the cold, most importantly due to the presence of solutes, ions, dissolved oxygen, etc. Rotting and rusting of facilities and ducts.

Corrosion is one of the most important problems in the cooling tower and causes cost loss and reduced efficiency of the tower. The presence of various factors in the tower makes it easy for corrosion to occur in the cooling tower. The presence of water as an electrolyte and also the presence of metals of different types in the tower as cathode and anode provides the basis for creating a chemical cell on a large scale.

Corrosion in steam boilers is caused by chemical and electrochemical reactions of metal with its surrounding environment. The most important corrosion factors in steam boilers are oxygen corrosion, carbon dioxide corrosion, corrosion due to pH drop, alkalinity corrosion, corrosion of hydrolyzable salts and corrosion of organic materials.

Hydrogen sulfide is an almost stable gas in the range of temperatures and pressures used in oil and gas exploitation systems, although in the presence of strong oxidants such as O2 and + Fe3, it can turn into elemental sulfur, which usually occurs in gas pipelines. It happens with high pressure or storage facilities. Hydrogen sulfide in concentrations higher than 80% is also found in some oil and gas reservoirs.

Corrosion in various industries, including in the oil and gas industries, imposes heavy sums of money to replace or repair equipment and machinery every year. Every year, 5% of the country's gross national product is wasted due to corrosion, and out of this 5%, about a fifth of it occurs in the oil, gas and petrochemical industries. One of the types of corrosion in oil and gas industries is corrosion caused by hydrogen sulfide gas.

In industries such as oil, gas and petrochemical, there is always an attempt to prevent the formation of deposits using different methods in equipment such as heat exchangers and boilers. In this field, a lot of money is spent on chemical materials and additives. But most industrial heat exchangers are exposed to sedimentation due to various reasons such as the low quality of water in different areas. These deposits are mostly formed in the pipes of the converters. In order to reduce the losses caused by sedimentation, the converter must be continuously monitored and cleaned.

Mitreh cooling tower antifouling is one of the innovative products of Abrizan company. Using an excellent combination, this product serves all industries and huge buildings that use cooling towers to exchange and remove water heat. By preventing the formation of sediment, the mitreh product increases the performance of this system, a system that plays the role of a heat exchanger.

همانند موجودات زنده که بدون آب نمی توانند زنده بمانند، پالایشگاه های نفت و کارخانه های پتروشیمی نیز بدون آب نمی توانند کار کنند. آب در سیستم های خنک کننده آبی، برای تهیه بخار و سیستم اطفا حریق استفاده می شود. فرآورده های نفتی و سوخت هایی که پس از تقطیر و فرآیندهای مختلف کاتالیزوری و کراکینگ تولید می شوند، باید سرد شوند. آب بهترین سیال برای این کار است.
