Industrial Applications of Corrosion Inhibitor & Demulsifier

Corrosion Inhibitor

Corrosion is a natural process that affects many industries worldwide. Corrosion not only affects the quality of the environment bit also affects the durability of the industrial equipments. Hence, it is important to use corrosion control methods for improving the lifespan of the infrastructure and saving huge expenses in equipment. Corrosion inhibitor is a chemical compound that effectively decreases the corrosion rate. The performance of a corrosion inhibitor majorly depends on the composition of fluid, water quantity and flow regime.

Industrial Applications of Corrosion Inhibitor

Corrosion Inhibitor in the Marine Industry: In the marine industry, aluminium and mild steel is mostly used for constructional purposes. Even after using high-quality metal, they are affected by corrosion with time. Because of the heavy machinery used in the marine industry, corrosion not only results in large expenses, but also becomes a safety hazard to the environment and people. The corrosion inhibitor helps in preventing such situations and improves the lifespan of the machinery. The usage of corrosion inhibitor also helps in reducing the maintenance cost, resulting in more profits.

Corrosion Inhibitor in the Automobile Industry: Corrosion is not only dangerous for the body of the vehicle, but it can also affect the engine severely. Inhibitors are used in a variety of applications in the automobile industry. It is used to prevent pipeline rusting and corrosion. Additionally, oil-soluble corrosion inhibitors are added to the lubricant oils to safeguard the engine from corrosion.

Corrosion Inhibitor in Wastewater Treatment Plants: As a result of rapid growth in urbanization, the demand of the wastewater treatment is increasing day by day. Steel is one of the most preferred materials used for sewage pipes in wastewater treatment plants, which can be affected by rust and corrosion. Corrosion inhibitors are used to protect the sewage pipes from corrosion and improve their lifespan.

Apart from these industries, corrosion inhibitors are used in many other industries like petroleum, metals, cement & concrete, power generation, mining, transportation & manufacturing, chemical processing, pulp & paper, and electronics and textiles.


Demulsifiers are chemicals used for separating emulsions. They are very important in wastewater treatment and crude oil production. There are various methods that can be applied for destabilizing the emulsion like increasing emulsion temperature, modifying the physical characteristics of the emulsion and adding chemical demulsifier. However, the most commonly used method is the addition of chemical demulsifier.

Industrial Applications of Demulsifier

Demulsifiers in the Petroleum Industry: The number of onshore and offshore crude oil fields, producing crude oil and water emulsion are constantly increasing. Because of the natural surfactants like asphaltenes and resins, these emulsions are formed in the process of oil exploitation. Water and oil separation is required before the transportation and refilling of oil. And, demulsifiers are used to break water-in-oil emulsion.

Apart from these industries, Demulsifier have various industrial applications in Petro Refineries, Crude oil, Oil-based Power Plants, Sludge Oil Treatment, and Lubricant Manufacturing.
