Saiptech's Rasching Supper Ring-Proven In Practice
The revolutionary idea behind the design of the Raschig Super-Ring has now also led to exceptionally good mass transfer efficiencies, pressure drops and loading capacities in the FRI test facility. The structure of the Raschig Super-Ring is the first to pursue the objective of producing turbulent film-type flows and to prevent formation of drops. The large number of alternating wave swings also achieves large turbulences in the gas and liquid flows while at the same time it has an extremely open geometry. Owing to the fluidicallyoptimized shape of the Raschig Super-Ring, the randomly dumped packed bed automatically obtains a structure otherwise found only in the case of structured packings.
