Abstract Experiments on liquid distribution have been carried out to study the effects of variation in packed height, air and water loads and corrugation channel angle of structured packings on the liquid distribution quality in a large-scale cold-flow column. Under the condition of uniform initial distribution, although the height of packing is within 2 m, the uneven distribution of liquid always exists, especially in the wall area, the uneven distribution is more serious. The liquid random distribution model based on experiments can predict maldistribution at different scales in structured packings.
