Flow through packed bed reactors
WebPacked beds are used to clean gas streams. As the animation below shows, gases flow up through the packed bed, shown by the arrows from orange to yellow, and the scrubbing liquid flows down the bed, shown by the arrows from blue to violet. Contaminants are transferred from the gas stream to the liquid stream. WebFlow in packed beds, as in open tubes, can be characterized by Reynolds number (Re), where dpis now set equal to the diameter of the particles in the packed bed. In order …

WebTrickle bed reactors are solid-liquid-gas contacting devices wherein a liquid stream flows downward over a bed of catalyst with pressure difference serving as the driving force. The fluid flows over catalyst particles and forms fine films, rivulets, or droplets. The gas stream can either flow concurrent with the liquid or countercurrent to it ... WebA fluidized bed is a packed bed through which fluid flows at such a high velocity that the bed is loosened and the particle-fluid mixture behaves as though it is a fluid. Thus, when a bed of particles is fluidized, the entire bed can be transported like a fluid, if desired. Both …
