Raschig Ring is designed to be made of PP material in a very small form and is maximized in the minimum area. This filling system, which is preferred especially in gas washing systems and deodorizing systems, is made of 1st quality material in white color and has high heat resistance.
Its main purpose is to expand the surface. It is generally used in gas washing systems and absorption towers. In cooling tower systems, it can be used as filling. In absorption towers, it washes the gas with water and is a deodorizing agent. It also cleans the waste.
Due to recent advancements in structured packing the technical window where application of random packing is optimum is reduced significantly. Use typically limited to columns of very small diameter where structured packing is more difficult to fit in and the disadvantages of a lower efficiency and hence taller column have less economic impact.
