TL;DR: In this paper, mass transfer of CO2 is studied in a polypropylene hollow fiber membrane contactor when the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate is used as the absorption liquid.
Abstract: Carbon dioxide (CO2) and sulfur dioxide (SO2) are typical gases produced during coal combustion and their emissions have to be controlled and minimized in order to reduce environmental risks. Organic solvents are commonly used as absorption liquids for the chemical absorption of CO2 and SO2, and their use in combination with a membrane device is being studied recently. The volatile character of common solvents produces solvent losses due to their evaporation into the gas stream. Thus, the use of solvents with lower vapor pressure such as ionic liquids as absorption liquids may contribute to the performance of a zero solvent emission process. In the present study, mass transfer of CO2 is studied in a polypropylene hollow fiber membrane contactor when the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate is used as the absorption liquid. Mass transfer coefficients are compared with those obtained with a ceramic hollow fiber contactor for SO2 absorption. The overall mass transfer coefficient takes a valu...

TL;DR: In this article, experimental measurements of the volumetric liquid mass transfer and bubble size distribution in a vertically oriented semi-batch gas-liquid Taylor-Couette vortex reactor with radius ratio η = ǫ/r/rǫ −075 and aspect ratio Γ −= h/(ro −− �) −40 were performed, and the results were presented for axial and azimuthal Reynolds number ranges of Rea −119 −143 and ReΘ −= 0 −35 −×104, respectively.

TL;DR: In this article, the effect of gas flow rate, liquid flow rate and diffusivity of the solute in the gas phase on the gas-side mass transfer coefficient was investigated in laboratory packed columns containing 38 in. (0.95 cm) ceramic Raschig rings.
