Ceramic Raschig Ring Tower Packing: Properties, Specifications and Industrial Applications
Ceramic Raschig rings are produced from high-alumina, low-iron clay combined with feldspar, quartz, and forming additives through a series of processes including ball milling, iron removal, vacuum pugging, molding, drying, and high-temperature firing. Key chemical indicators: acid resistance ≥ 99.6%, alkali resistance ≥ 85%, maximum operating temperature 1000°C, Mohs hardness > 6.5, water absorption < 0.5%. The material resists corrosion from various inorganic acids, organic acids, and organic solvents, with the exception of hydrofluoric acid. Ceramic Raschig rings are employed across multiple industries: Chemical processing: drying columns, absorption columns, scrubbing towers, and regenerating towers in chemical, metallurgical, coal gas, and oxygen production industries. Environmental engineering: desulfurization, denitrification, and volatile organic compound treatment systems, as well as wastewater treatment towers. Catalyst support: ceramic Raschig rings serve as covering an...
