| Abstract: | The hydrodynam ics and transfer properties in a 40 m 3 airlift reactor w ithoverflow ing w indow s and second air sparger for industrialuse have been studied. The ef fects ofsuperficialgas velocity, liquid loading and second air sparger upon the m ain designparam eters: gas holdup, recycling liquid velocity, oxygen transfer coefficienthave been in vestigated experim entally. Expressions relevant to these param eters w ere also derived. Am odel describing m ixing behavior w as established. Its effectiveness in use of industrialscale up have been verified by practice. |
