Metal Raschig Ring

Metal-Raschig rings were developed by F. Rasching in 1914. They are among the earliest fixed geometric shape packing materials. Their design is simple, with height and diameter being equal. Large Raschig rings (over 100mm) are typically packed using a structured, regular filling method, while Raschig rings with a diameter of 75mm or less are usually packed using a random filling method.

Detail

Metal Raschig Ring Packing is a common industrial filler that is widely used in the separation process of gas and liquid, such as fractionation, absorption, evaporation, etc. Lassi ring packing is designed to provide good gas-liquid contact efficiency and mass transfer performance while maintaining a low pressure drop. Metal lassi rings are usually short cylindrical in shape, with a large inner diameter and a smaller outer diameter, and are similar in height to diameter. This design helps to create a good flow channel in the packing layer. It is commonly made of corrosion-resistant metal materials such as stainless steel and nickel alloy, and is suitable for various chemical media and high temperature and high pressure working conditions. The design of the metal lassi ring provides a large specific surface area, which facilitates gas-liquid contact.


Metal Raschig Ring


The shape and layout of the metal lassi ring helps to enhance gas-liquid contact and improve mass transfer efficiency, making it suitable for a wide range of separation processes. The relatively good fluid flow properties allow the metal Lasi ring packing to maintain a low pressure drop and reduce energy consumption. The use of metal materials allows the Rassi ring to work stably even in extreme environments. Metal fillers can be cleaned or recycled to restore their properties, which is more economical. The good design allows the fluid to flow more evenly in the packing layer, reducing dead zones and uneven flow.


Metal Raschig Ring


It is widely used in fractionation columns in the petrochemical industry to improve separation efficiency. It is used in the gas absorption process to enhance the contact efficiency between gas and liquid. As a packing material for catalytic reactors, it increases the contact area between reactants and catalysts and promotes chemical reactions. In wastewater treatment and wastewater recycling, metal lassi ring fillers help to remove contaminants from water and improve water treatment results. Improve separation efficiency in the separation and purification process of hydrogen, nitrogen and other gases.
