Definitions

  • the present invention relates to a process for the purification of gaseous effluents.
  • the present invention relates to a simple and relatively inexpensive method for destroying smelly compounds in gaseous effluents. It is based on the discovery by the applicant that the reaction of ozone, very slow at room temperature with the amino and sulfur compounds and practically zero with the aldehydes, becomes very rapid at high temperature, especially above 140 ° C. Indeed, these three classes of compounds constitute the main causes of pollution.
  • the method according to the invention is characterized in that the gaseous effluents are subjected to the action of ozone at high temperature, preferably at a temperature above 140 ° C.
  • temperatures from 150 ° C to 250 ° C will be advantageous.
  • ozone in excess of the stoichiometric amount necessary for the total oxidation of the malodorous compounds present in the effluent to be treated is added to the effluent and the mixture is introduced continuously, in an externally heated reactor, the residence time of the mixture in this reactor being of the order of one or more seconds.
  • EXAMPLE 1 Air containing 15 ppm of n-butyraldehyde is preheated to 220 ° C., added with 40 ppm of ozone and introduced continuously into a reactor heated to 220 ° C., the residence time in this reactor being 1.5 seconds. The residual n-butyraldehyde is assayed by flame ionization and CO 2 by infrared absorption. It can be seen that, at the outlet of the reactor, 90% of the n-butyraldehyde has been eliminated and transformed into non-odorous species including CO 2 and H 2 O.
  • Air containing 20 ppm of trimethylamine preheated to 180 ° C. supplemented with 60 ppm of ozone is introduced continuously into a reactor heated to 180 ° C., the residence time in this reactor being 2 seconds. It can be seen at the outlet of the reactor that more than 95% of the trimethylamine has been eliminated, and transformed into non-odorous species including CO 2 and H 2 O.
