Bubbling reactor

WebA bubble column reactor provides more liquid holdup than an agitated vessel type reactor. Hence, it requires a smaller volume for chemical reaction controlled gas—liquid reactions (for slow and very slow gas—liquid reactions). 2. The agitated vessel-type reactor provides a higher heat transfer coefficient than a bubble column reactor. WebA bubble column reactor requires less maintenance than an agitated vessel reactor. 3. A higher interfacial area is obtained with an agitated vessel type reactor. Agitation reduces the bubble size and thereby increases the interfacial area of contact, which in turn increases the mass transfer rate. 4. A bubble column reactor consumes less power.
