Abstract
A regular economically producible packing of use in chemical engineering equipment is described. Physico-chemical phenomena in thermal separating and mixing apparatuses in particular are associated with contacts between different phases in cocurrent and countercurrent operation. The important feature of an appropriate packing design is to intensify transverse mixing in the flowing phases and to intensify contact between them. This purpose is served in the packing according to the invention not only by known fan-like vane elements but also by a number of channels rows which are parallel to one another and offset from one another, the effect of such rows being to boost transverse mixing and phase contact of the flowing media, more particularly when the lighter phase flows at elevated speed.
