Surfactant, Oilfield Chemicals, Demulsifier, Corrosion Inhibitor

Oilfield Chemicals
The oilfield chemicals are used to drill oil and gas. There are various types of oilfield chemicals like demulsifiers, corrosion inhibitors, cosmetics self emulsifying wax etc. Each one of them is briefed below:-

Demulsifier (Emulsion Breakers)

Demulsifier also known as emulsion breakers is used to separate water from oil. To avoid corrosion problems, the water and salt are removed from the crude oil before refining, which can be done only with the help of demulsifier. Thus, the most common use of a demulsifier is to process crude oil. The two types of demulsifiers like oil soluble demulsifier and water soluble demulsifier are used depending on the emulsions to be separated.

Corrosion Inhibitor

The chemical compound which can decrease the corrosion rate of a metal or an alloy when added to liquid or gas is known as corrosion inhibitor. The corrosion inhibitors can prevent internal corrosion from hydrogen sulphide, carbon dioxide and oxygen in oil & gas production systems. Oil soluble corrosion inhibitors, water soluble corrosion inhibitors and water dispersible corrosion inhibitors are some of the corrosion inhibitors.

Cosmetics Self Emulsifying Wax

An ideal medium for blending fluid cosmetics containing oil and water is cosmetic self emulsifying wax. It is used in industries into production of cosmetics, lotions and soaps. The structure of soaps, crèmes and lotions are complemented by the self emulsifying wax. Non ionic self emulsifying wax and ionic self emulsifying wax are two types of emulsifying waxes. The non ionic self emulsifying wax is white, odourless, flakes and is ideal for preparation of ointments, liquid emulsions, lotions and crèmes. A self emulsifying cream base is known as non ionic self emulsifying wax. Its is used for preparing ointments, lotions, crèmes and also liquid emulsions. Non ionic self emulsifying wax is prepared from high purity cetearyl alcohol and polysorbate 60 providing excellent stability. Anionic self emulsifying wax is also known as emulsifying wax NT and produces high quality lotions and crèmes which are very smooth. Anionic self emulsifying wax is general purpose emulsifiers which is suitable for pharmaceutical and cosmetic applications.

Surfactant

Surfactants are organic compounds which contain both, hydrophobic group and hydrophilic group. Hydrophobic group is repelled by water which means it does not like water and hydrophilic group are attracted towards water and tend to dissolve in water. So 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. Surfactants act as an emulsifier also. Everybody knows, that it is very much difficult to mix oil and water as they have different properties. But, surfactants have those properties due to which oil and water can be mixed together and thus oily substances can be removed with the help of surfactants. Each and every 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.
