Sita ring packing

Thread Content

The Sita ring packing is known as stainless steel θ mesh ring packing, also referred to as Dixon packing; it is a type of high-efficiency packing made from metal wire mesh, with its diameter equal to its height. The common specifications include 2×2, 3×3, 4×4, 5×5, 6×6, 7×7, 8×8, 9×9, 10×10, 11×11, 12×12, etc. Due to the capillary action of the metal mesh, the liquid can be evenly dispersed into a film, facilitating thorough mass and heat transfer between the gas and the liquid, and effectively eliminating unstable phenomena such as channeling. The pressure drop of the θ-ring filler is related to the gas velocity, liquid spray rate, specific gravity of the system, surface tension, viscosity, and the characteristics of the filler, as well as the amount of pre-foaming treatment applied to the filler. The amount of material retained in the θ-ring filler is greater than that of similar solid fillers, and its surface wettability is also higher than that of ordinary ceramic rings; as a result, its film formation efficiency is high, leading to an even higher separation efficiency. The number of theoretical plates for θ-ring packings decreases as the packing size and tower diameter increase; this is particularly evident for packings used in towers with small diameters. An increase in tower diameter results in a significant reduction in the number of theoretical plates (when Dr/d>10, HETP=0.8–1.2Dr, while when Dr/d>70, the packing efficiency drops significantly). It increases as the gas velocity rises, and decreases as the surface wetting rate of the packing decreases. θ-ring packing is mainly used in laboratory settings and for the separation of small batches of products with high purity.
