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. For more details visit http://www.rimpro-india.com/demulsifier.html
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.
