Microemulsion formation in offgas scrubbing
An offgas containing an organic compound is scrubbed by providing a spray of a scrubbing fluid containing a water-soluble organic surfactant, an organic cosurfactant comprising an alkanediol and water. The spray is mixed with an offgas containing a volatile organic compound, thereby forming an oil-i...

| Zusammenfassung: | An offgas containing an organic compound is scrubbed by providing a spray of a scrubbing fluid containing a water-soluble organic surfactant, an organic cosurfactant comprising an alkanediol and water. The spray is mixed with an offgas containing a volatile organic compound, thereby forming an oil-in-water microemulsion and reducing content of the organic compound in the offgas. The process and apparatus of the invention are especially suitable for scrubbing offgas generated by aluminum rolling mills. |
