The specification of stainless steel ball ring packing requires the addition of lubricant during use due to insufficient lubricant content in the layered packing. How to choose fillers? The selection of fillers includes determining the type, specification, and material of the fillers.
The selection of fillers includes determining the type, specification, and material of the fillers. The selected filler should not only meet the requirements of the production process, but also have low equipment investment and operating costs. The selection of packing types takes into account the requirements of the separation process, usually considering the following aspects: high mass transfer efficiency. Generally speaking, the mass transfer efficiency of regular packing is higher than that of bulk packing. The flux needs to be large. On the premise of maintaining high mass transfer efficiency, packing materials with high flash point gas velocity or gas-phase kinetic energy factor should be selected.
Stainless steel ball ring packing materials include stainless steel and carbon steel. Due to its thin processing wall, high porosity, high flux, low resistance, heat resistance, corrosion resistance, and good separation effect, it is suitable for vacuum distillation towers to handle materials that are heat sensitive, easily decomposed, prone to polymerization, and prone to carbon deposition.
The Bower ring has made significant improvements on the basis of the Raschig ring, with two rows of window holes with internal protruding tongues on the ring wall. This structure improves gas-liquid distribution and fully utilizes the inner surface of the ring. Compared with the Raschig ring, the processing capacity can be increased by more than 50%, while the pressure is reduced by half.
Features: Ball ring packing has the characteristics of low pressure drop, high flux, and high efficiency. HYPAK packing has lower pressure drop and higher mass transfer efficiency compared to PALL rings of the same size, and the liquid distribution in the packing layer is good.
Application: Suitable for various separation, absorption, desorption devices, atmospheric and vacuum distillation units, synthetic amine decarbonization, desulfurization systems, ethylbenzene separation, isooctane, methyl benzene separation, etc. Price of stainless steel ball ring and stainless steel packing.
Metal fillers can be made of various materials, and corrosion is the main consideration when selecting. Carbon steel fillers have low cost and good surface wetting properties, and should be prioritized for use in non corrosive or low corrosive systems. Stainless steel packing has strong corrosion resistance and can generally withstand corrosion from common systems other than Cl -. However, its cost is high and its surface wetting performance is poor. In some cases (such as vacuum distillation under low spray density), surface treatment is required to achieve good performance.
