Protection of heat exchangers: dealing with corrosion and increasing efficiency

The use of various types of heat and refrigeration exchangers in the industry is very wide and its importance is clear. The utilization rate of heat exchange equipment directly affects process efficiency and cost. According to statistics, heat exchangers account for almost a fifth of the investment in an industrial production process. Therefore, the interest rate and lifetime of converters is an important issue. In terms of exchanger damage, corrosion is a very important reason. Corrosion and loss of metal due to the presence of corrosive and oxidizing agents causes the formation of layers of metal oxides on the surface of the alloy. Between the layers of metal oxides, corrosive agents with active ions are trapped and cause the development of sub-deposit corrosion. Corrosion product deposits can lead to the destruction of the equipment in a short time. Therefore, the removal of this oxide layer is important to protect the system against pitting corrosion, prevent the development of corrosion and increase the heat transfer efficiency (ΔT) in the exchanger.

Special sediment vector solutions for removing corrosion deposits.

Special sediment vector solutions for removing corrosion products produced by Abrizan Company are recommended for removing metal oxide layers from the surface of the exchanger. The mechanism of action of this solution is that it reacts with metal oxides and forms a chelate with their metal ions. As a result, a significant part or all of the corrosion products are separated from the walls and dispersed into the water.
