Abstract

In order to discuss mass transfer behaviors between volatile organic compound (VOC) and triethylene glycol (TEG) solutions affected by surface tension and equilibrium process. The packed-bed absorption system and the equilibrium system were designed. TEG solution was chosen as the working solution in this study, and the tested VOCs included methanol, methyl ethyl ketone (MEK), toluene, and ethyl ether. Experimental results showed that the order of absorption performances was methanol, MEK, toluene, and ethyl ether in the initial concentrations of VOCs were 24.05% mol and 14.50% mol. This result agreed with the prediction by the equilibrium concentration.
