“…Juvinal et al (1970) provide an extensive literature review of fixed bed collection. Blasewitz and Judson (1955) compared the performance of glass fiber filters and sand bed filters for the removal of methylene blue aerosols from gas streams flowing at 1.5 to 2.0 cm/sec. Thomas and Yoder (1956) collected DOP aerosol in sand filters and on lead shot at low flow velocities; aerosol collection efficiencies increased when the bed operating mode was changed from an upflow pattern to a downflow pattern indicating gravity settling.…”

others or some small pores which hinder diffusion. The selective tailing observed in the case of p-diisopropylbenzene might plausibly be related to the relative size of adsorbent pores and this particular molecule.In summary, we have demonstrated four continuous adsorptive separations that resulted from pulse test information. This information is reasonably quantitative with respect to equilibria, semiquantitative and empirical with respect to rates, and qualitative with respect to tailing. Formal modeling of the test will permit more quantitative formulation of the information. However, even in its present form it is very effective in continuous process development.Literature Cited

“…Eight fiber types gave promise of efficiencies approaching that of a HEPA filter. Only one, the Owens Corning Fiberglas• type 115K, was satisfactory under field conditions (Blasewitz et al 1951). A permanent curl in this fiber is the key to performance of the 115K fiber.…”

“…Filtration superficial velocity is defined as the actual volumetric flow rates through the filter divided by the cross-sectional area of the filtration zone. In the studies on fixed beds of glass fibers, Blasewitz and Judson [18] discovered that the collection efficiency dropped with increasing filtration superficial velocity. On the other hand, Moresco and Cooper [19] developed a correlation form for penetration showing that high Stokes number and high filtration superficial velocity caused the increase of collection efficiency.…”
