Ceramic pall rings are originated through improvement of raschig ring. Their open structures effectuate separation of gas and liquid streams and thus facilitate a more effective mass transfer. And decrease the pressure drop. It is the top leading manufacturer, supplier, exporter for ceramic pall ring column packing.
