Title: Process and apparatus for the ozone treatment of a liquid material
IPC: C02F9/00
Filed: 1972-10-13
Abstract: 1363608 Ozonation of polluted liquids GENERAL ELECTRIC CO 13 Oct 1972 [3 Nov 1971] 47315/72 Heading C1C A process for the ozone treatment of liquid material comprises (A) introducing a major portion of the liquid into the upper portion of a first ozonation zone, (B) introducing the remaining portion of liquid in the upper portion of a second ozonation zone, (C) introducing ozone into the lower portion of the first ozonation zone, (D) removing ozone-treated liquid from the lower portion of the first ozonation zone, (E) conducting a gaseous stream from the upper portion of said first zone to the lower portion of the second ozonation zone, (F) removing a liquid product from the lower portion of the second ozonation zone, (G) conducting a gaseous stream removed from the upper portion of the second ozonation zone to an ozone generating zone, and (H) removing ozone-containing gas from said ozone-generating zone and conducting it into the lower portion of said first ozonating zone wherein the second ozonation zone is smaller in size than the first ozonation zone but provides a more efficient per unit volume contact between the liquid material and the gas flowing therethrough than the per unit volume contact provided by the first ozonation zone. The liquid material is preferably waste water from a silicone-polymer-producing plant. The liquid material entering the first and second ozonation zones is preferably at a temperature between 0‹ and 60‹ C. A cooling zone may be positioned between the ozonation zones. The ozonation zones may be within one column, the first zone being in the bottom portion and the second zone being in the upper portion of the column. The process may be carried out in the apparatus shown in the accompanying Figure in which a portion of liquid material is fed via line 1 to tower 4. The towers 4 and 13 are packed, e.g. with Raschig rings made of porcelain, clay, carbon or plastics. An ozonecontaining gas is fed from generator 23 to tower 4 via line 8, and ozone-treated liquid is subsequently removed from this tower via line 9. A vapour stream leaves the tower via line 10 and is introduced into the second tower 13. The remaining portion of liquid material from pipe 1 is fed into the top of the second tower. Ozonetreated liquid is removed from the base of this tower through line 17 and united with similar material leaving tower 4 via line 9. A vapour stream passes out of the top of the second tower via line 18a, is passed to de-entrainer 18b for removal of liquid, is then passed to dryer 21 and thence to ozone-generating device 23.

[Also in Divisions B1-B2] Polyurethane coatings are prepared by reacting in a solvent organic polyisocyanates with aliphatic.cycloaliphatic di- and polyols which are obtained by the hydrogenation of addition products of phenols or phenol derivatives having at least one exchangeable hydrogen atom to (A) unsaturated, straight- or branched-chain alcohols with 10 to 48 carbon atoms or their alkoxylated products or to (B) unsaturated straight- or branched-chain carboxylic acids with 10 to 48 carbon atoms or their esters with alcohols containing 1 to 4 carbon atoms, and/or reaction products of these aliphatic-cycloaliphatic di- and polyols with ethylene oxide or propylene oxide. Suitable phenols or phenol derivatives are phenol, polyhydric phenols, alkyl phenols, halogenated phenols, and polynuclear phenols. Alcohols suitable for forming the addition products are decenol, dodecenol, hexadecenol, oleyl alcohol, linoleyl alcohol, linolenyl alcohol and particularly alcohols obtained from natural oils, fats and waxes and unsaturated Guerbet alcohols. Carboxylic acids suitable for forming the addition products are undecylenic, oleic, elaidic, erucic, brassidic, tall oil fatty acids, linoleic, elaeostearic and linolenic acids, dimeric fatty acids and particularly acids obtained from natural waxes, oils or fats, and the methyl, ethyl, propyl, isopropyl and butyl esters of such acids. The phenols or phenol derivatives may be reacted with the alcohols or acids or their esters in the presence of aluminium silicates activated with mineral acids with a pH value of 3 to 5, as catalysts, and the resulting product hydrogenated in a conventional manner, suitably in the presence of a powdered copper-chromium oxide catalyst activated with barium chromate. The phenol addition products or their hydrogenated derivatives may suitably be reacted with 1 to 6 mol. of ethylene oxide or propylene oxide, followed by hydrogenation if necessary. Conventional aliphatic or aromatic polyisocyanates may be used. Suitable solvents are ethyl acetate, ethylene glycol diacetate, benzene, toluene, xylene, methylene chloride and dioxan. Substantially stoichiometric quantities of polyisocyanate may be used, but when ethylene oxide or propylene oxide addition products are used an excess of polyisocyanate up to an NCO : OH ratio of 4: 1 is recommended. Cross-linking of the products may be achieved by including trimethylolpropane in the isocyanate/polyol reaction mixture, and catalysts, especially triethylamine, may be used.
