Gas-liquid mass transfer of impinging streams microreactor
摘要
Abstract
Vortex conoid impinging streams, T-shaped vortex streams and twice vortex streams reactors were designed based on the T-shaped impinging streams reactor. Their averaged gas-liquid interfacial specific surface area a and liquid mass transfer coefficient kt were experimentally measured by chemical absorption method when gas-liquid is contacting. The effects of the inlet configuration, size and fluid flux of the reactor on the mass transfer performance were discussed. The experimental results show that the liquid mass transfer coefficient of the vortex reactor is higher than that of impinging streams reactor, and the liquid mass transfer coefficient of the twice vortex reactor is higher than that of vortex reactor. The liquid mass transfer coefficient increases with the decrease of inlet size and the increase of fluid flux. The liquid side volumetric mass transfer coefficients are at least one or two orders of magnitude higher than that of the conventional gas-liquid contactors, thus the averaged gas-liquid interfacial specific surface area is greatly enhanced.关键词
