Nur Chemicals has been extensively involved with demulsifier formulations since 1994 working actively in different petroleum fields hand in hand with their customers. Nur formulates a line of demulsifiers that are applicable to light, medium, and heavy crude oils. Nur's demulsifier products are surface active agents that are formulated upon the specification of the crude oil types.

Water-in-oil emulsions are formed during the production of crude oil. The stability of the emulsion is ranging from a few minutes to years depending on nature of the crude oil, crude oils consist of hydrocarbons such as alkanes, nephtenes, and aromatic compounds as well as phenols, carboxylic acids, and metal, some of these components can form films at oil surfaces, and others are surface active.

So, the tendency to form stable or unstable emulsion of different kind varies greatly among different oils. The process of Demulsifier or Emulsion Breaker of a water-in-crude oil emulsion involves the acceleration of the coalescence as well as the film rupture process.

Dispersed water droplets approach each other and flatten to from a thin film of continuous oil phase between them.
