Eine einfache Apparatur für die kontinuierliche Stofftrennung aus der Gasphase

Continuous, regenerative, two-dimensional extraction. 1. Experimentation and computer simulation

“…All of these two-dimensional systems feed the material to be separated at a single point in the cascade and hence greatly dilute the product, besides utilizing the cascade inefficiently. Several different physical forms of two-dimensional cascades have been studied, viz., the packed rotating annulus (Martin, 1949;Nicholas and Fox, 1969;Canon et al, 1980), the stationary annulus and rotating feed/product headers (Andrew, 1981), the rotating plate (Sussman et al, 1972), and the nonrotary GLC apparatus (Turina, 1962). Other two-dimensional separations are reviewed by Wankat (1984).…”

Retention in continuous two-dimensional thermal field-flow fractionation: comparison of experimental results with theory

“…11 Continuous separation is achieved in the dipole magnetic fractionator (DMF) [12][13][14] using a eld-ow conguration identical to that of continuous free-ow electrophoresis. Turina et al 15 described a continuous twodimensional gas-liquid chromatographic apparatus, but only preliminary experiments were carried out. Giddings 16 described in theory a continuous annular gas chromatograph.…”

Gas Chromatography

“…Schulz and coworkers (448,511) used vibration of the column in the vertical direction to favor uniform packing and transport of the descending sorption material and a gas lift to continuously convey the packing to the head of the column. The moving bed technique was also used by Fitch et al (180) to separate close-boiling volatile liquids and by Turina et al (585) who allowed the liquid phase to descend by gravity between two parallel disks while the gas was flowing through the,carrier in a horizontal direction. Bradley and Tiley (67) separated azeotropic liquids by allowing a flow of nonvolatile solvent over a stationary packing to produce a simple differential vapor absorption process.…”
