Advantage
1) These tower packings are made from chemical porcelain andhave excellent resistance to acids except in the case ofhydrofluoric acid.
2) Moisture absorption must less than half a percent.
3) The porcelain’s specific gravity is2.3-2.4g/cm3 and an average heat capacity (between 20°Cand 500°C of 0.22 cal/g.°C)
4) Kelley ceramic tower packing softening point is1400°C min. And they show good thermal shock resistance duringrepeated cycling between 20°C and 820 °C
| | Ceramic saddle isimproved from the arc saddle, Ceramicsaddle changes the both arched surface torectangular surfaceand makes the interior radius of curvature different, this construction overcomes the problem of nesting basically,Ceramic saddle makes porosity distributedeven and improves the distribution of the fluid, greater capacityand lower pressrue drop than Rasching ring.Chemicalanalysis. | SiO2 | >73% | | Al2O3 | 17-25% | | Fe2O3 | <1.0% | | CaO | <0.5% | | MgO | <0.5% | | K2O Na2O | 2-4% | | Other | <0.1% |
