Background: Different packing materials are used in wet scrubbers that each one has its own advantages and limitations. Common ceramic packing materials have high removal efficiency but they are heavy, fragile and high head loss along the bed. Finding a suitable replacement for these materials has always been concerned by researchers. The objective of the present study was to compare the ...
In this paper a packed bed of char particles is considered for experimental study and analysis. The packed char bed is modelled by extending the single-particle analysis (Dasappa et al., 1994a, Chem. Eng. Sci. 49}2: 223}232. Dasappa et al., 1994b, 1wenty-,fth Symposium (International) on Combustion, pp. 1619}1628. Dasappa et al., 1998, 1wenty-seventh Symposium (International) on Combustion, pp....
Background Monoclonal antibodies (Mabs) have been recently used for the treatment of virtually every debilitating disease. Packed-bed bioreactors have been used for the cultivation and production of a wide range of cell lines and biologics including MAbs. The principle behind a Packed-bed bioreactor is that the cells are being immobilized within a suitable stationary matrix which is represented...
Electrospun nanofiber membranes surface functionalized with 3D nanolayers through ATRP provide adsorption capacities over 50-times higher than current commercial membrane adsorption systems and over 12-times higher than packed bed resins; additionally, the adsorption kinetics remain 10-times faster than packed bed resins and have over 15-times higher permeance.
Expanded Bed Adsorption enables the protein recovery directly from cultivations of microorganisms or cells and preparations of disrupted cells, without the need for prior removal of suspended solids. The performance ofan expanded bed is comparable to a packed bed owing to reduced mixing of the adsorbent particles, clogging/plugging of solid particles in the column, while fluidized bed requires ...
