Impact of HSPBT blade angle on gas phase hydrodynamics in a gas–liquid stirred tank

open access: yes, 2018
For gas dispersion applications in stirred tanks, standard pitched blade turbine (PBT) with 45° blade angle is widely used. However, the standard PBT suffers from low pumping efficiency as well as high torque instability when a large volume of gas is to ...

The influence of polymeric membrane gas spargers on hydrodynamics and mass transfer in bubble column bioreactors

open access: yes, 2016
Gas sparging performances of a flat sheet and tubular polymeric membranes were investigated in 3.1 m bubble column bioreactor operated in a semi batch mode. Air–water and air–CMC (Carboxymethyl cellulose) solutions of 0.5, 0.75 and 1.0 % w/w were used as
