Preparation of de-emulsifier of gemini surfactant and it's applications in an oil industry

Abstract EN

A Gemini surfactants (GS) is a bis quaternary amoniun salt.

It is prepared from tetramethyl ethylene diamines (TMEDA) with cetyl bromide, while an ordinary surfactant (OS), which is quaternary ammonium salt, is prepared from trim ethyl amine (TMA) and cetyl bromide.

They were identified by elemental analysis and IR spectroscopy.

Comparing the GS, OS and the commercial surfactants, the Gemini surfactant shows interesting properties and has a variety of uses, such as a de-emulsifier.

Adopting the composition ratios found in the study of reverse chemistry of commercial demulsified, Rp6000, which is usually used in the south and north oil companies in Iraq.

The prepared active reagent was characterized by various techniques, IR spectroscopy, elemental analysis, melting point, solubility, flash point and functional group analysis.

The efficiency of the prepared de-emulsifier was examined by standard methods and compared with the efficiency of the commercial Rp6000 based on the same wet crude oil sources.
