چکیده انگلیسی
The gas-liquid two-phase flow and mass transfer with fast chemical reaction in a microchannel were investigated experimentally. Result showed that the bubble volume decreased exponentially with its movement along the channel in a quickly reactable absorbent. The volumetric mass transfer coefficient kLa increased with gas flow rate, while it was insensitive to liquid flow rate under experimental conditions, although the mass transfer coefficient kL increased with liquid flow rate. In slug-bubbly flow regime, the kL decreased when increasing gas flow rate, but inverse tendency was found for slug flow pattern. Both kL and kLa increased with the increase of absorbent concentration. A new correlation for predicting the volumetric mass transfer coefficients kLa was proposed by taking the enhancement factor E of chemical reaction into account.
