ABSTRACT:
Water-in-oil emulsions containing by weight about:20 to 80% of a dispersed aqueous phase containing about 20 to 70% of one or more aldehydes chosen from the group constituted by formaldehyde, glyoxal, glutaraldehyde, glycolaldehyde or glyoxylic acid and 80 to 30% of an aqueous solution containing 90 to 100% water and 10 to 0% of a buffer agent pH=5.5.+-.1.5; and 80 to 20% of a continuous oil phase containing about 90 to 99 % of one or more saturated and liquid C.sub.6 -C.sub.16 hydrocarbons, and 10 to 1% of an emulsifying system constituted by one or more water-in-oil emulsifying agents and process for the elimination of hydrogen sulphide.
