Precipitation of hydrocarbon compounds

Fouling in Heat Exchangers

Fouling refers to the accumulation of undesirable materials on the heat exchange surfaces of heat exchangers. These undesirable materials can include insoluble compounds in the fluid, polymer compounds and process by-products, inorganic salts, corrosion products, etc., which precipitate in heat exchangers due to thermal shocks. In other words, the formation of deposits is the result of the accompanying phenomena of heat, mass and momentum transfer in transient conditions, which occurs on the surface of the heat exchanger and causes a change in the operational efficiency of the exchanger.

The importance of preventing the formation of deposits in heat exchangers

In the oil, gas, refining and petrochemical industries, there is always an effort to prevent the formation of deposits in equipment such as heat exchangers by using various methods. Because deposits in heat exchangers and heat transfer equipment are one of the main economic problems that cause increased energy supply costs, increased pressure drop, reduced process efficiency, corrosion damage and reduced equipment useful life. Cleaning and descaling of heat exchangers is considered one of the most basic needs in industries. In industry, even the smallest amount of sediment is not acceptable.

Challenges and solutions for removing hydrocarbon sediments

In the oil and gas industries, deposits made of hydrocarbon compounds are also often seen, which deposit on heat transfer surfaces along with other insoluble organic and inorganic compounds present in the fluid and corrosion products. These types of deposits are usually hard and sticky, and special sediment carriers based on hydrocarbon solvents are used to remove them. However, some sediment compounds are not soluble in common hydrocarbon solvents. These types of sediments usually contain complex and heavy hydrocarbon-polymer compounds along with compounds such as corrosion products or mineral compounds such as carbonate and sulfate compounds. The use of physical methods for removing deposits causes damage to the equipment and failure to completely remove deposits from the equipment, and the remaining deposits in the exchanger cause the formation of deposits in a shorter time. The sediment removal technique must be economical, fast, and without damaging the equipment. Among the sediment removal methods, the use of chemical washing with safe and efficient solutions with a controlled corrosion rate is recommended.
