Abstract
The present disclosure belongs to the field of chemical products for petroleum conditioning, in particular demulsifying agents. This disclosure concerns the application of terpolymers based on combinations of alkyl acrylates, aminoalkyl acrylates, and alkoxyalkyl acrylates, to destabilize water-in-oil (W/O) emulsions, in order to remove the emulsified water and salts dissolved in it, specifically, in the triphasic separation units for crude oils with API densities from 8 to 40° API.
