Ceramic Structured Packing
Structured Packing because of its uniform and symmetric, stipulated flow path, has been widely used in the field of fine chemicals, petrochemicals, fertilizer. It has the advantages of compression, large flux, and high separation efficiency.
Ceramic corrugated packing is a new type of structured packing that consists of many packing units with the same geometry. Due to the unique structure of ceramics and good hydrophilic properties, the surface can form very thin liquid film turbulence and the oblique zigzag channel of the gas flow can promote the gas flow without blocking the gas flow, this makes the ceramic packing can compete with the metal packing. Its corrosion-resistant and high-temperature resistant that metal packing cannot be compared. The surface structure has good wetting properties, which can make the liquid flow faster and minimize the liquid retention of the packing. This reduces the chance of overheating, polymerization and coking.
Ceramic structured packing Ceramic corrugated packing advantages
Large flow. The new tower design can reduce the tower diameter, and the old tower transformation can greatly increase the throughput.
High separation efficiency. It has much larger specific surface area than random packing.
Low pressure. Can save a lot of energy.
Large operation flexibility, and the amplification effect is not obvious.
Suitable for various of tower diameters.
Strong acid and alkali resistance, especially H2S, naphthenic acid chloride ion corrosion.
Ceramic structured packing application
Distillation of halogenated organic compounds
The rectification and absorption processes of corrosive mixtures with strict pressure drop and theoretical number of plates.
Sulfuric acid absorption, nitric acid enrichment, and gas purification of chemical fertilizer plants, etc., which have a large number of intrinsic media.
Vacuum operation up to 100Pa absolute pressure.
Used as heat exchanger, mist eliminator or catalyst carrier.
