oil reclaiming methods. SUBSTANCE: methods consists in spray drying of water-in-oil emulsion or microemulsion containing water-soluble or swelling-in-water vinyl polymer; method consists of the following phases: (a) spray drying of dispersion, emulsion, water-in-oil emulsion or microemulsion containing water-soluble or swelling-in-water vinyl polymer; (b) co-condensation of oil and water generated at spray drying, thus obtaining condensed oil and condensed water and (c) separation of condensed oil from condensed water, thus obtaining reclaimed oil which contains not gaseous agents in the amount of lesser than 0.1% by mass of total mass which impede polymerization. EFFECT: possibility of re-using reclaimed oil without effecting polymer properties. 17 cl, 11 tbl |
