Raschig ring is a form of random packing and is used in commercial fractional distillation columns to reduce pressure loss (versus using trays), while maintaining good efficiency and economy. The Raschig ring packing is proven in a wide range of mass transfer applications. The Raschig ring structure provides one of the largest surface areas among tower packing options and handles heavy loading, process upsets and temperature shocks.
Raschig ring is an artificial filler earliest industrial use. Usually made of ceramic or metal sheet having a height equal to its diameter, the size of conventional 25mm ~ 75mm (also as small as 6mm, large up to 150mm). Ceramic wall thickness of 2.5mm ~ 9.5mm, the metal ring is 0.8mm ~ 1.6mm, in the case of strength permits, should be thinned wall of the ring. Raschig rings Although mass transfer performance is not ideal, but because of the simple structure, easy to manufacture, low price, some factories still employ.
