Anti-fouling and anti-corrosion of refrigeration systems

Corrosion and scale problems in cooling systems

One of the main problems of cooling systems is corrosion and scale formation, which causes a lot of damage in the industrial sector every year and creates a lot of problems for industries by consuming too much water and fuel for heat exchange. For this reason, inhibitor materials are used to protect systems against such problems. Inhibitor materials used in cooling systems are materials that are added to water in low concentrations to prevent any type of corrosion and prevent the formation of scale. Therefore, scale inhibitors and corrosion inhibitors should be used to increase the productivity and efficiency of the system and prevent the formation of scale on the walls of exchangers, surfaces of facilities and piping, and also to reduce the corrosion rate in facilities.

It is important to note that before using inhibitors, the system must be close to the zero design point in terms of scale, so it is necessary to use scale-removing materials and ensure that the system is free of scale before injecting inhibitors.

Choosing the right anti-scaling and anti-corrosion solution

Anti-scaling and anti-corrosion products come in different types that are selected according to the type of system and the operating conditions of the system. In open circuit, semi-closed circuit and closed circuit systems, the type of anti-scaling and anti-corrosion material is different. Also, the type of alloys used in the cooling system circuit also has a great impact on the selection of the right inhibitor.

Anti-scaling and anti-corrosion products generally have azole, nitrite, phosphate and zinc-phosphate bases. These products are used in systems such as condensers, cooling towers, chillers, various types of exchangers, building engine room cooling systems, etc. Given that injecting the right dose of inhibitor solution (no less, no more) has a great impact on controlling the system in optimal conditions, regular monitoring of the inhibitor used in the system is essential based on international standards.

Introduction of MSA1110 Industrial Mitreh Scale Removal, Anti-Scaling and Anti-Corrosion Solution:

General Industrial Mitreh Scale Removal, Anti-Scaling and Anti-Corrosion Solution MSA1110 with three simultaneous functions has a special formulation and is in the field of advanced chemicals. This solution has cathodic inhibition properties and forms a permanent layer on the cathode surfaces of metals by the mechanism of scale formation through electrical decomposition. It also has anodic inhibition properties because the said film can also include metal ions. This solution also inhibits the formation of scale. The presence of dispersing polymer compounds in this solution prevents the settling of sedimentable compounds on the metal surface and consequently disperses the sediments. Polymers that have an irregular shape become regular in structure when they enter the sediment crystal and cause it to disintegrate. This solution also contains chelating agent compounds. The chelant is composed of two functional groups, a highly soluble group on one side and a hydrophobic group on the other. The soluble group combines with the metal ions present at the interface with the solution and forms an insoluble layer on the metal surface, and the hydrophobic group creates a barrier against the soluble group. As a result, the formation of deposits and corrosion on the metal surface is also prevented by a neutralization mechanism. Due to the presence of special polymer compounds and special catalysts in the MSA1110 solution, this solution reacts with the deposited compounds and penetrates into the deposit structure, eliminating the deposit layers of carbonate, sulfate and corrosion products. The presence of corrosion inhibitors in this solution causes this reaction to continue until it reaches the metal surface, but does not react with the main metal or this reaction is very insignificant.

Quality Approval of Industrial Mitreh Solution

Tests conducted on industrial miter solution in reputable centers including the Petroleum Industry Research Institute, Razi Research Institute, Shiraz University, Housing and Urban Development Research Center, and Iran Petrochemical Research and Technology Company, and the satisfaction of consumers of this solution are confirmation of the high quality and special performance of this solution. Industrial miter solution is environmentally friendly and biodegradable.
