Polypropylene Pall ring packing ring packing a high diameter equal openings every fenestrae 5 lingula each lingula bend point ring center, contrary to the position of the upper and lower levels of fenestrae staggered generalthe opening area accounts for about 30% of the total area of the ring wall. Has large porosity, low pressure drop and mass transfer unit height, high flooding point, full of vapor-liquid contact, small specific gravity, high mass transfer efficiency.
This structure improves the distribution of the vapor-liquid, full use of the inner surface of the ring, so that the packing column of gas and liquid can be free from the form can be.
