Compared with the later, pall ring has improved the liquid distribution of packing layer greatly, with open windows on ring sidewall. Therefore it has productivity, low resistance, operating flexible and higher efficiency. Hualai Pall ring is widely applied to industry. It is still one of major annular random packing that has been adopted. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.
