Abstract
The paper reports on the process of deposit formation for water-in-oil emulsions of paraffinic and highly paraffinic oils of varying water content. The effect of additives based on polyalkylmethacrylates on the quantity and composition of deposits of water-in-oil emulsions was explored. As shown, the inhibiting ability of K-210 additive was increased upon the deposit formation of water-in-oil emulsions compared to the initial oil. Herewith, the efficiency of its foreign analogue, Flexoil additive, was reduced. As determined, the nature of a change in the composition of paraffinic hydrocarbons in emulsion deposits of anhydrous oil systems was the same in the presence of additives. Therefore there remained the same effect of additives in the presence of water in the oil system.
