В данной статье рассмотрено влияние различных факторов и выявлены некоторые зависимости при разделении водонефтяной эмульсии типа «вода в нефти». Было выяснено, что с повышением температуры и хлористых солей эффективность разрушения водонефтяной эмульсии увеличивается, также влияние оказывает рН-среда, значение которой ближе к нейтральной. Высокая обводненность сырой нефти оказывает благоприятное воздействие на дестабилизацию и отделение эмульгированной воды, а наличие асфальтенов значительно затрудняет сепарацию сырой нефти. Растворитель, входящий в состав деэмульгатора, также играет большую роль в дестабилизации эмульсии и подбирается индивидуально.

This article discusses the influence of various factors and reveals some dependencies in the separation of water-oil emulsions. It has been found that the efficiency of water-in-oil emulsion separation increases with the increasing of temperature and chloric salts content. Near to neutral pH medium has an impact on the separation of emulsions. High water cut of crude oil has a beneficial effect on destabilizing and separation of emulsified water, whereas the presence of asphaltene makes the crude oil separation difficult significantly. The solvent included in the demulsifier plays a large role in emulsion destabilization and it is selected individually.
