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.

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.

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.

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.

Just as living organisms cannot survive without water, oil refineries and petrochemical plants cannot function without water. Water is used in water cooling systems, to provide steam and fire extinguishing systems. Petroleum products and fuels produced after distillation and various catalytic and cracking processes must be cooled. Water is the best fluid for this.
