Ceramic fillers Partition Ring for RTO, lessing ring
Ceramic lessing ring is a packing designed basically from the raschig ring with partitions inside to increase the surface and enhance the transfer efficiency. It is usually used extensively for the supporting packing at the bottom of tower. It has high density and excellent acid resistance and it withstands the corrosion of various inorganic acid, organic acid and organic solvents expect for hydrofluoric acid.
