Product Description
Ceramic rings with a cross-shaped partition
Ceramic rings with a cross-shaped partition inside belong to regular acid-resistant packings for distillation and rectification columns. They are placed (stacked) in the working chamber of the apparatus in a certain (ordered) way. Ceramic Cross Partition Ring is a packing designed basically from the Raschig Ring with the cross-partitions inside to increase the surface and enhance the transfer efficiency. Ceramic Cross Partition Rings are available to the order of sizes: 2" (50 mm), 3" (80 mm), 4" (100 mm),5" (120 mm), 6" (150 mm).The final price for Ceramic rings with a cross-shaped partition depends on the quantity, delivery terms and form of payment.
Chemical reaction in a reactor (designations on the diagram):
Rings with a cross-shaped septum have a high resistance to acids (>99.6%) and virtually no water absorption (<0.5%), and heat resistance is at least 8 heat shifts. Ceramic rings have high throughput and low hydraulic resistance. This reduces energy costs for transporting the gas mixture through the column, increasing the efficiency of chemical equipment.
Our company is engaged in the production and sale of ceramic packing, including Ceramic Cross Partition Rings. All our products pass strict quality control and comply the necessary standards. Since we are a manufacturer and dealership margins are not included in the price of the final product, we have a low price for Ceramic Cross Partition Rings. Corresponding quality documents are provided. Ceramic Cross Partition Rings are supplied in factory packaging. Detailed technical specifications and dimensions Ceramic Cross Partition Rings are shown below.

Application of Ceramic Cross Partition Rings
Ceramic rings with partition are used in the chemical, metallurgical and processing industries, in sewage treatment systems and in the production of mineral fertilizers. The ceramic material of the packings shows high resistance in aggressive environments. Parts are staggered into the tank to create additional channels for flow movement.
Elements are loaded into a packed column to create a larger contact surface between dissimilar substances. The liquid is absorbed by the pickings on its own plane flows down, and gas flows rise up the column. Intensive mixing and mass transfer between phases continuously occurs throughout the entire area filled with packed bodies. Because this packing normally has a very large size, it is applied as ceramic supports for random packings.
Cross-shaped rings are used for various purposes:
to increase the contact of the environment in the reaction columns containing gas-liquid and liquid phases;
for cleaning phases from components absorbed by a liquid;
in oil refining processes – for separation of a phase into fractions by a heating method at various temperatures;
in separation columns – to isolate gas compounds dissolved in a liquid.
Acid resistant packings are also a natural heat storage unit in air cleaning units. The shape of the fillers excludes the creation of stagnant zones of liquid and the formation of through channels for the passage of phases
