Advantage
Due to its unique design structure, it has high mechanical strength, high porosity, low resistance, large specific surface area and high mass transfer efficiency.
Application
The application of ceramic stepped ring packing is as follows:
1.in the occurrence tower and distillation tower of fine chemical equipment that are prone to polymerization blockage;
2.In the production of synthetic ammonium and urea, the gas purification process in the CO2 absorption tower, such as replacing the original ceramic Lassie ring with a DN50 ceramic stepped ring, has increased the production capacity of the tower and improved its operational performance. The modified regenerated gas CO2 purity has also been significantly improved;
3.The application of ceramic stepped ring fillers in the drying and absorption towers of tail gas acid production processes in smelters such as gold, copper, zinc, and lead has been very successful.
