The Plastic Pall Ring represents an enhancement over the rasching Ring. While they share similar cylindrical dimensions, the plastic pall ring distinguishes itself with two rows of punched-out holes, featuring fingers or webs directed towards the center of the cylinder. This plastic pall ring design modification significantly enhances the packing’s performance in terms of throughput, efficiency, and pressure drop when compared to rasching Ring.Each leaf tongue ring in turn point to heart, upper and lower levels of the location of the opposite window at different times and in general Central area of wall openings about the total area of about 30%. With porosity, and pressure drop and low height of mass transfer unit, the pan-point high, vapor-liquid contact with the full, the proportion of small, high mass transfer efficiency.Pall ring structure improves the vapor-liquid distribution, make full use of the inner surface of the ring, so that the tower fill the gas and liquid form from the free passage.<\/p>\n
