Corrugated packing is a high-efficiency packing widely used in countries around the world. Its main advantages are:

1) High theoretical plate number, large flux, and reduced pressure;

2) Good low-load performance, the theoretical plate number increases with the reduction of gas load, and there is almost no low-load limit;

3) Large operating flexibility;

4) The amplification effect is not obvious;

5) It can meet the requirements of precision, large-scale, and high-vacuum distillation equipment. It provides favorable conditions for the distillation and separation of difficult-to-separate systems, heat-sensitive systems, and high-purity products.

Corrugated packing mainly replaces the old bulk packing in the tower to solve the outstanding problems of large resistance, small specific surface area, poor mass transfer efficiency, and easy breakage. It can be widely used in gas washing towers, coking benzene washing, naphthalene washing, ammonia washing towers, fertilizer hot gas saturation towers, desulfurization, and desulfurization towers.
