Electro-absorption unit for the removal of volatile organic compounds and odorants in gas streams
ES2967558
Electro-absorption unit for the removal of volatile organic compounds and odorants from gas streams. An electro-absorption unit for the treatment of gas streams contaminated with volatile organic compounds and odorants, where the unit combines an absorption column in the upper part with an electrochemical cell in the lower part. Both parts are adjacent and in contact through a support grid for the packing of the absorption column. The electrochemical cell also includes, in a lower cover, conductive supports for connecting the electromotive force source to the electrodes. The gas to be degraded enters through the interface between the support grid and the column, flowing countercurrently to the liquid phase.
The present invention falls within the technical field of treating contaminated gas streams using two techniques, absorption and electro-oxidation, combined into a single operating unit, electro-absorption. The invention is defined as an electrochemical reactor combined with an absorption column for the removal of volatile organic pollutants and odor compounds. Integrating the oxidant generation and absorption systems into a single physical space offers several significant advantages in terms of process efficiency.
