Abstract

The present disclosure belongs to the field of chemical products for petroleum conditioning, in particular to the field of demulsifying agents. The disclosure concerns the application of random terpolymers based on alkyl acrylate-ethylene alkanoate-alkoxyalkyl acrylate to destabilize simple emulsions of the water-in-crude oil (W/O) type and/or complex emulsions of the crude oil-in-water-in-crude oil (O/W/O) type present in crude oils with gravities from 6 to 40° API, in order to remove the emulsified water and salts dissolved in the latter. Its application is mainly focused on wells to avoid formation damage caused by emulsions, in offshore units, triphasic separation units, and in onshore units prior to the refining process.
