Ceramic Pall Ring
Ceramic Pall rings are a type of classic random packing developed on the basis of a Raschig ring. Usually, the packing has two holes with bends inside the cylinder wall. Each hole has five tabs that are bent to the axis of the ring, the ceramic Pall ring is completely identical in shape to the metal and plastic Pall ring. However, the number of holes and bends may vary depending on the height and diameter. In General, the open surface of the packing should occupy 30% of the total area of the cylindrical wall. This design allows steam and liquid to pass through the holes with ease, and allows full use of the inner surface of the ring to separate steam and liquid. This also improves separation efficiency.
