Ceramic Cross Partition Ring Ceramic Cross Partition Ring is a kind of random packing further improved on the basis of Raschig Ring, adding the cross clapboard inside the ring. It increases the ring’s surface area, improving significantly the mass transfer efficiency of vapor and liquid. Generally, cross partition ring is required to stack orderly in the column due to its big size. Currently, cross partition rings, size between Φ80-Φ150mm, are used as the support material of other random packing at the bottom of column, which accumulation voidage is over 60%. With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, Cross Partition Ring can resist high temperature, acid (except HF), alkali, salt and various organic solvents. It's widely applied in various packing towers of desiccation, absorption, cooling, washing, and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation.   Technical Specification Size, mm D x H x T, mm Surface area, m²/m³ Free volume, % Number per m³ Bulk density , Kg/m³ Dry Packing Factor, m-1 Φ 50 50x40x50x5 145 50 6400 600 565 Φ 80 80x64x80x8 120 56 1950 820 356 Φ100 100x80x100x10 110 53 1000 850 252 Φ120 120x96x120x12 75 55 370 860 146 Φ150 150x120x150x15 60 58 295 980 101 Ceramic Super Saddle Ceramic Super Saddle is a kind of random packing further developed on the basis of Saddle Ring, which both smooth edges are changed to hackly or ripple edges. Comparing with normal saddle, such structure of super saddle can ensure that interspace will be increased a lot when saddles are stacked in the column randomly. Therefore, the resistance to vapor-liquid is decreased and it facilitates flow and distribution of vapor-liquid through the packing bed. As a result, pressure drop is low and mass transfer efficiency is high. With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, Super Saddle can resist high or low temperature, acid (except HF), alkali, salt and various organic solvents. It's widely applied in various packing towers of desiccation, absorption, cooling, washing, and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation.   　 Chemical Index Index Value Porosity (Vol%) 1 Specific heat (KJ/Kg) 840-900 Crush strength (N/mm2) 390-420 Specific gravity (g/cm3) 2.3-2.45 Acid resistance (%) 99.98 Firing temperature (℃) 1280 – 1320 Softening temperature (℃) >1400 Density (Kg/m3) 2300 – 2400 Water absorption (%) <0.2 Thermal expansion (10-6mm/mm℃) 4.7 Hardness Scale (Moh's) 7 – 8 Comprehensive strength (N) 5600 Shock strength (Kgf.cm/cm2) 1.0 – 1.5 Chemical Composition Index SiO2 Al2O3 SiO2+Al2O3 Fe2O3 CaO MgO K2O+Na2O Other Value >69% 15-23% >92% <1% <0.25% <0.2% 2-4% <1% Technical Specification
