Surfactant
The organic compounds which contain both, hydrophobic group and hydrophilic group are known as surfactants. The hydrophobic group doesn’t like water is it is repelled by whater whereas hydrophilic group is attracted towards water and so when both the groups combine, they enable to form different structures. When surfactant is dissolved in water, hydrophobic group and hydrophilic group enable to form different structures as they are having different reactions towards the water. Thus, the surfactant can act as an emulsifier also which can remove dirt from the surfaces. It is very much difficult to mix oil and water but due to surfactants, it can be done easily and thus oily substances can be removed with the help of surfactants. Each and every unique surfactant has different characteristics and properties. Depending on the type of the charge of the head, a surfactant belongs to the anionic, cationic, non-ionic or amphoteric family of surfactants.
Oilfield Chemicals
The oilfield chemicals are used to drill oil and gas from the oilfields. There are different types of oilfield chemicals used for which are mentioned below:-
Demulsifier
The demulsifiers can separate water from oil and the most common use of a demulsifier is to process crude oil because it avoids corrosion problems. The demulsifier helps in removing water and salt from the crude oil before refining. The electrostatic forces of repulsion reacting between the water droplets can be decreased with the help of demulsifiers. Oil soluble demulsifiers and water soluble demulsifiers are two types of demulsifiers and the decision of which type of be used depends on the emulsions to be separated.
