Which of the following processes is not an example of adsorption applied to gaseous separations ?
Correct answer: A. Decolouration of yellow glycerine
- A. Decolouration of yellow glycerine
- B. Dehumidification of air and gas
- C. Removal of objectionable odour and impurities from industrial gases
- D. Recovery of valuable solvent vapors from dilute mixture with air and other gases
Explanation
Decolouration of yellow glycerine is adsorption from a liquid, commonly using activated carbon, rather than separation from a gas. Solvent-vapour recovery, gas dehumidification, and odour removal are gaseous applications.
