In addition, coalescing filters protect equipment from damage caused by contaminants, resulting in longer equipment life and reduced downtime for maintenance and repairs. Using coalescing filtration in industrial processes can also lead to increased efficiency and longevity of equipment. Increased Efficiency and Longevity of Equipment Coalescing filters are particularly effective in removing oil and water droplets from the air, which can cause corrosion and damage to equipment. These filters are essential in maintaining the quality of compressed air systems, as they ensure that the air is free from contaminants that can cause damage to equipment and compromise product quality. Coalescing filters work by trapping and eliminating submicron-sized liquid oil, water droplets, and solid particulate matter. Removal of Oil, Water, and Particles from Compressed Air SystemsĬoalescing filtration is a process that is widely used in industrial settings to remove oil, water, and particles from compressed air systems. It has the potential to improve the efficiency of production processes, reduce costs, and improve product quality. The Benefits of Coalescing Filtration in Industrial ProcessesĬoalescing filtration is an essential process in many industrial settings. The denser water molecules coalesce and fall to the bottom of the tank for drainage. Similarly, in gas-water separation, ‘wet gas’ (gas stream containing water droplets) is fed into the coalescer inlet, diffuses through the filter element, and exits via an outlet port as dehydrated gas. Meanwhile, the water vapor molecules diffuse through the filter element to coalesce and be drained out of the system gravitationally. In water-oil separation, the baffle walls in the coalescing filter divert the heavier oil molecules in one direction to a drain point. The screening mechanism works based on the physical properties of the component substances, e.g., molecular weight and density. Thus, the components of interest can be recovered in pure form while the contaminants are drained away for purification or disposal. A stream of fluid to be separated (e.g., a gas-water mixture) is applied to the filter, and the baffles screen out the various components by trapping them in different sections. How Does a Coalescer Work?Ī coalescing filter (or simply coalescer) is a filtration system consisting of several baffle walls or screens. ![]() Coalescing filters are employed in various industries, such as oil & gas and chemical plants.Ĭommon types include the gas coalescer, oil coalescer, fuel coalescer, and condensate coalescer, which can be used for water-gas, gas-oil, and fuel-gas separation. What Does a Coalescing Filter Do?Ĭoalescence can separate the components of homogenous or heterogeneous mixtures and emulsions. ![]() Coalescing filters can separate particulate components of mixtures at comparable efficiencies as particulate filters. Coalescence is a process whereby fluid molecules agglomerate (come together) to form a larger whole. What Is a Coalescing Filter?Ī coalescer or coalescing filter is a device used to separate fluid mixtures into individuals utilizing the principle of coalescence. A coalescer is an industrial device used for this purpose. The presence of water vapor, sulfur, ethane, methane, carbon dioxide (CO 2), and other impurities in industrial process fluids and products necessitates precision filtration systems for quality control of the final products.
