The aim of this study was to determine the effectiveness of industrial mitreh solution in reducing the corrosion rate of commonly used metals exposed to industrial water environments. The results showed that using mitreh solution significantly reduces the corrosion of metals made of plain carbon steel and stainless steel in DM water.

The effect of chlorine and chloride parameters on the corrosion of stainless steels and the parameters affecting their corrosion rate, as well as the acceptable limits of chlorine ion levels in water and the differences in the effects of free chlorine and chloride on the corrosion of corrosion-resistant steels, are stated.

One of the main factors of scale in building installations is the presence of calcium carbonate in water, because the solubility of this compound in water is very low and if the conditions are right, it will precipitate quickly. One of the parts that provides these conditions is the surfaces in contact with water in heat exchangers in domestic gas-fired boilers (heat packages).

The affinity of some metals in a corrosive environment initially increases normally with increasing concentration of corrosive agents (oxidizing power of the solution), and metal corrosion is intensified, but at a certain concentration of corrosive agents, the corrosion rate suddenly decreases significantly and the metal loses its affinity and becomes inactive. The reason for the reduction in corrosion at a certain concentration of oxidizing components is the formation of a protective or inactive layer on the metal surface. The protective layer can be oxide, hydroxide or other compounds. This phenomenon is called rusting.

Downhole corrosion is one of the most important problems facing the oil and gas industry. By using various methods such as selecting appropriate materials, surface coating, use of corrosion inhibitors and cathodic protection, the corrosion rate can be significantly reduced. A better understanding of corrosion mechanisms and the development of new technologies can help improve efficiency and reduce costs in this industry.

Any system where temperature and water are the main elements for its operation inevitably requires the invention of Abrizan Company, called Industrial Mitreh, because wherever there is temperature and water, the formation of sediment is inevitable, unless a substance is used that suspends these sediments. This is the main function of an excellent anti-sediment solution.

Corrosion is a phenomenon that occurs in most environments, so no industry can be safe from the costs of corrosion. For example, the oil, gas and petrochemical industries, factories and heavy manufacturing industries (iron smelting, steelmaking, etc.), transportation, water and wastewater, are among the industries that are severely affected by this phenomenon. This section attempts to briefly examine corrosion in several important industries.

Cold Mitreh, a water-soluble solution with a high dissolution rate, is introduced as a powerful scale remover and an innovative product of Abrizan Company. Cold Mitreh was developed in response to the industry's need for an alternative solution to descalers. Descalers are scale removers based on hydrochloric acid and are highly dangerous, toxic, and corrosive.

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.

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.

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 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.
