Solubilization Absorption of Toluene Vapor by Formation of Oil-in Water Microemulsions with Cation Surfactants
Absorption reactors to remove volatile organic compounds from gas streams can be retrofitted, as volatile organic compounds act as oils and form microemulsions. Using the region of microemulsion in the phase diagram as the indicator, the main influences on the solubilization capacity of various microemulsion systems were investigated. When the mass ratio of the surfactant (cetyltrimethylammonium bromide) to the cosurfactant (tetrabutylammonium bromide) was 1:1, the microemulsion was the best absorbent. Comparative absorption tests of microemulsion, distilled water, and surfactants were performed in a double-stirred reactor. The results indicate that the microemulsion has a relatively higher absorption rate and absorption capacity than the other absorbents.
