Anti-foaming additives (anti-foaming agents, defoamers) - are used in various refining processes such as hydrotreating: During hydrotreating of crude oil or other petroleum products, foam is formed due to the presence of various impurities and reactions. Anti-foaming additives help to reduce the intensity of foam formation and prevent its accumulation, which can lead to efficient hydrotreating operations. Also during refinery cooling and condensation processes of vapors or gases, foam can form, which can lead to reduced process efficiency and equipment damage. Anti-foaming additives help prevent foam formation and provide more efficient cooling and condensation. In some catalytic processes used in petroleum refining, foam formation may occur due to the interaction of the catalyst with other components. Anti-foaming additives can be added to prevent foaming and provide more stable operation of the catalytic system.
