Review of Various Kinds of Airlift Bioreactors and its Effective Hydrodynamic Parameters

Airlift bioreactors form one of the most important classes of gas-liquid contactors that are extensively used in chemical and biochemical processes especially in oil and gas industries. These bioreactors have some advantages respect to CSTR and BCRʹs especially in bioprocesses. In this article, various kinds of airlift bioreactors have been investigated. Design or scaling of the bioreactors is depend on the hydrodynamics turnover, that inclusive using parameters such as gas velocity, void fraction, liquid velocity and mixing. Because of the rigorous interaction, behavior study of these bioreactors are complicated. In this research, effective hydrodynamics parameters in the airlift bioreactors are investigated. In the recent years, computational fluid dynamic (CFD) as tools for study the airlift bioreactors were used. CFD methods and their application in simulation of airlift bioreactors have been introduced and investigated.
