Random packing is used for mass and heat transfer applications. The first packing, the Raschig ring, was developed in 1915. Over the years, industry has furnished a number of designs, many of them tailored or optimized for specific applications. Vendor catalogs frequently indicate surface area, say 30 sq.ft./cu.ft, and void space, say 96 %. In practice, the actual or effective surface area can be augmented by an aggregate of sprays, bubbling, dripping, droplet splash, among others. Effective or actual surface area can be as well diminished by fouling/plugging/blocking, and unused or idle sections. 

Typical applications include absorption, stripping, heat transfer, pollution control, distillation, olefin manufacturing and liquid-liquid extraction.
