1.	Airlift reactors generally do not provide better mixing than bubble columns.(a) True(b) FalseI have been asked this question in class test.My question is from Bioreactor Configurations topic in section Reactor Engineering of Bioprocess Engineering
Answer» The correct ANSWER is (b) False Easy explanation: Airlift reactors generally PROVIDE better mixing than bubble columns except at low liquid velocities. The airlift CONFIGURATION confers a degree of stability to liquid flow compared with bubble columns; therefore, higher gas flow RATES can be used without INCURRING operating problems such as slug flow or “spray formation”.
