Theses

Glass and glass-lined, stirred-tank reactors are of significant importance in the pharmaceutical and related industries. Because of fabrication issues, a retreat blade impeller (RBI) with a low impeller clearance off the tank bottom is commonly used in glass-lined reactors, typically combined with a single baffle (providing only partial baffling conditions) mounted from the top of the reactor. In addition, these reactors are often provided with a torispherical bottom. Other configurations are also used, including full baffling or no baffles at all, hemispherical bottoms, and different impeller types. Despite their common use, some of the most important mixing characteristics of this …
