Ceramic raschig rings, one of the earliest chemical packing types, are cylindrical with circular open ends, crafted from ceramic materials. As a key component of tower internals, they find extensive applications in chemical processes like distillation, absorption, and extraction. Their performance directly impacts mass transfer and heat transfer efficiency, with the Characteristic Shape Factor (CSF) emerging as a core parameter to evaluate this. CSF comprehensively considers specific surface area, porosity, and geometric shape, determining the packing’s hydrodynamics and mass transfer characteristics.

The Characteristic Shape Factor, often denoted by ψ, is calculated by the formula ψ = (6ε)/d_p², where ε is porosity (the proportion of space available for fluid flow) and d_p is the packing diameter. A higher ψ value indicates a larger specific surface area and better fluid distribution, thereby improving mass transfer efficiency while reducing pressure drop. However, traditional Raschig rings have relatively low ψ values due to their simple structure, limiting their use in high-efficiency separation processes.
Helvo, a professional manufacturer specializing in such packing, excels in optimizing the Characteristic Shape Factor. By precisely controlling ceramic material formulation and molding processes, Helvo’s Raschig rings maintain mechanical strength while significantly increasing ψ. Its unique structural design ensures uniform flow of gas and liquid through the packing layer, minimizing backmixing and enhancing mass transfer efficiency by over 20%. With years of industry experience, Helvo’s ceramic Raschig rings have become the preferred choice for upgrading tower internals in chemical, environmental protection, and other fields, trusted globally for their superior performance and reliable quality.
