Mass Transfer in an Airlift Reactor with a Net Draft Tube

Biotechnology Progress, 1992
AbstractGas–liquid mass transfer in an airlift reactor with net draft tube is investigated. The effects of both the ratio of draft tube to reactor diameter and the reactor pressure on oxygen transfer are considered. The value of the volumetric mass transfer coefficient, kLa, increases with a decreasing diameter ratio at higher air flow rates.

Operating Conditions of Conical Spouted Beds with a Draft Tube. Effect of the Diameter of the Draft Tube and of the Height of Entrainment Zone

Industrial & Engineering Chemistry Research, 2007
The bed stability of conical spouted beds with a nonporous draft tube located at the bottom of the contactor has been studied, and these results have been compared with those obtained without internal devices, under the same experimental conditions. To design the appropriate geometry of the nonporous draft tube, as well as the height of the entrainment

Numerical simulation of the draft tube and tailwater flow interaction

Journal of Hydraulic Research, 2002
This work focuses on the numerical simulation of the interaction between the draft tube and tailwater flow in low head hydro power plants. An approach to the solution of incompressible free surface flow problems is developed. The flow field and the free surface location are calculated by coupling the free surface kinematic and dynamic conditions with ...

Liquid circulation in a draft-tube bubble column

Chemical Engineering Science, 1985
Abstract A study of liquid circulation in a draft-tube bubble column (250 mm diameter, 60l. capacity) using a flow-follower technique is reported. It was observed that annulus liquid circulation velocity increased to a maximum with air flowrate and a maximum in the volumetric liquid circulation rate occurred at a tube: column diameter ratio of about ...
