Demulsifiers, or emulsion breakers, are a class of specialty chemicals used to separate emulsions.Demulsification is used for the separation of water from crude oil. As crude oil is produced from a reservoir it tends to become mixed with either natural formation water or mixed formation and injection water.
As high-quality reserves are depleted, many oil recovery operations are relying increasingly on heavy crude oil reserves. To recover as much oil as possible from these reserves, crude oil demulsification is used for better oil separation. Breaking these emulsions helps to meet production targets, adhere to commercial crude oil specifications, and yield cleaner produced water for discharge or reinjection.
Demulsifier chemicals formulated to complement the crude oil dehydration process and enable efficient desalting of crude oil.
