Ceramic Cross-partition ring deign’s purpose is increase packing surface area to improve mass transfer effieiceny..Due to ceramic cross-partition ring belong to regular acid-resistant pickings for distillation and rectification columns.it will increase Cross shape septum in the ring’s inside. This design is not only enlarge packing surface area, but also increase its Compressive strength they are put (stacked) in packing layer position of the column. Additionally, large void ratio is rarely to cause channeling and Wall Flow Phenomenon happening, it is usally regard as tower bottom packing support layer.
