A concept of membrane CTF reactor applicable to gas-liquid processes has be
en presented. Its fundamental hydrodynamic and kinetic properties have been
discussed. In the experiments high values of the mass transfer coefficient
s, k(L)a, of the order of 0.1 s(-1) have been obtained and a relatively wea
k influence of the liquid viscosity on the values of the mass transfer coef
ficients has been observed. To eliminate moving elements of the reactor, a
replacement of the rotor by a static helical ribbon guide which forces the
helicoidal flow of the fluid has been proposed for the same operating condi
tions. (C) 1999 Elsevier Science Ltd. All rights reserved.
