Size of Bubbles and Gas Holdup in Bubble Columns

Miyahara Toshiro Department of Industrial Chemistry
Takahashi Teruo Department of Industrial Chemistry
Bubble columns are extensively used in the chemical industry. This paper evaluates the present state of the art on the size of bubbles from a sieve plate and gas holdup, mainly on the basis of the results of the authors, including previous ones. The size of bubbles formed from a sieve plate has an insignificant effect of chamber volume, and gas holdup shows some different behavior, depending on the hole diameter to liquid depth.
