One of the most important points in a heat exchanger is the overall heat transfer coefficient. This coefficient is obtained in terms of the conduction and convection resistances between the fluids separated by flat walls and cylindrical shells, respectively. The layer of scale on the surfaces may increase the resistance to heat transfer between the two fluids to a large extent. This effect can be taken into account by introducing an additional thermal resistance, called the fouling coefficient (Rf), and its value depends on the operating temperature, fluid velocity, and the operating time of the exchanger.

The purpose of this study was to investigate the effectiveness of Mitreh MDA0102 scale remover solution in industrial water environments according to NACE standards in two environments: calcium carbonate and calcium sulfate, and to compare it with acid washing. According to this study, this solution is a non-corrosive solution, unlike the solutions used in acid washing, which greatly increase corrosion. Also, the results of couponing indicated that the presence of Mitreh vector sediment solution will prevent further corrosion by forming a thin layer on the heat transfer surface.

Antiscalants are chemical compounds designed to prevent scale formation in water systems. By preventing scale formation on surfaces, these compounds can increase operational efficiency and reduce maintenance costs in industrial water treatment, oil and gas extraction, and desalination processes.

Analysis of the causes of cracks in the existing shell/tube exchanger and providing solutions to prevent similar incidents. The shell/tube exchanger is used to regulate the air temperature for drying granules in silos. Due to a leak in this exchanger after 5 years of operation, the tubes were separated from the shell and the tubesheet and tube areas were subjected to non-destructive inspections. It was found that many cracks had formed in the connection between the tubes and the tubesheet on the hot air inlet side, but no defects or discontinuities were observed on the air outlet side.

Mitreh Cooling Tower Anti-Fouling is one of the innovative products of Abrizan Company. This product, using an excellent composition, serves all industries and large buildings that use cooling towers to exchange and remove water heat. Mitreh's product prevents the reduction of the performance of this system by preventing the formation of fouling. A system that plays the role of a heat exchanger.

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.

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.

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.

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.

Boiler feed water should be free of hardness. Sometimes, due to the short or improper operation of the hardness device or the failure to regenerate the resins in time, some hardness enters the boiler feed water. Increasing the water temperature in the boiler reduces the solubility of water solutes. The water near the hot surfaces becomes saturated and the conditions for deposition of less soluble substances are provided and eventually sediment is formed.

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.

It has been about a decade since a new anti-scale solution entered the market, an anti-scale that plays an important role in protecting all types of heating and cooling systems from the formation of scale. This specialized product is called Mitreh and is a new invention of the Abrizan Company.

The steel industry uses large amounts of water. However, very little is consumed, as most of the water is reused or returned to the source. Water is used not only in cooling operations, but also in other processes such as scale removal and dust cleaning.

This term is the name of advanced products with scale removal, anti-scale and anti-corrosion properties that are designed to help optimize energy consumption and solve scale and corrosion problems in industrial water systems. The name "Mitreh" is derived from the ancient word "Mitreh" which means pact, friendship and sun. This name reflects the commitment of the creators of Mitreh to create a friendly relationship between industry and water.

Cooling towers, as the name suggests, are used for cooling. Equipment used in industry for heat transfer is one of the important equipments, among which cooling towers are effective and practical for the continuation and continuity of operations and other processes.
