raschig super-ring

RASCHIG SUPER-RINGProven in Practice and FRI testedFig. 3 shows the pressure drop per theoretical stage. Here the advantageof using our Raschig Super-Ring in mass transfer columns becomesespecially clear. Despite an extremely low pressure drop, the largeturbulence of the gas and liquid flow together with the especially goodsurface wetting causes an excellent mass transfer rate. The pressure dropper theoretical stage of the Raschig Super-Ring is therefore far below thatof Pall rings and other modern packings.Pressure Drop/stage, inch H2ORaschig Super-Ring No. 2 Pressure Drop per StageC6/C7 System, 24 psia (1.65 bar), F.R.I.
