Mass transfer in the two-phase helicoidal contactor

A concept of the membrane CTF reactor and the possibility of using it for g as-liquid (slurry) processes has been presented. A modified CTF reactor wit h rotating shaft replaced by a static helicoidal ribbon guide was proposed. The effects of such parameters as the gas-liquid mixture mass flow rate, t he ratio of volumetric flow rates of the phases: gas/liquid, a rotational s peed of the internal cylinder on the mass transfer in a two-phase system wa s determined experimentally. The influence of the liquid viscosity increase on the values of the volumetric mass transfer coefficients have been inves tigated. Experiments indicated high values of the mass transfer coefficient (k(L)a being of the order of 10(-1) s(-1)), particularly in a high viscosi ty liquid. A possibility to use CTF reactor in the wet air oxidation proces s for slurry and sludge wastes treating.
