Emulsification and demulsification of water-in-crude oil emulsion via microwave-assisted chemical treatment

Formation of emulsions during oil production and processing is a costly problem, both in term of chemicals used and production losses. The traditional ways of breaking emulsion using heat and chemicals are disadvantageous from both economic and environmental prospective. In this thesis, a new natura...

In this thesis, a new natural demulsifier knowing as “Cocamine MEA” in addition to an alternative energy potentials of microwave-assisted chemical approach were utilized and investigated in the demulsification of water-in-crude oil emulsion.

For the stability performance test, three non-ionic emulsifiers were used, namely; Triton X-100, Span 80, and Cocamide DEA. Among these emulsifiers, Span 80 and Cocamide DEA permit the highest stability for the prepared emulsion. For the chemical demulsification performance test, six emulsifiers having different properties were utilized, namely: Octylamine, Hexylamine, Dioctylamine, Cocamine MEA, Polyethylene Glycol (PEG 600), and Polyethylene Glycol (PEG 1000). Among these demulsifiers, Octylamine was found to be the best in separating water and oil phases (90-100%) followed by Hexylamine (80-90%) for emulsion based on Span 80 at different phase ratios, respectively. Meanwhile, Cocamine MEA at the dose of 1 vol.% was found to be the best in separating water and oil phases (90-100%) followed by Octylamine and Hexylamine (90-100 %) at the dose of 1.5 vol.% for emulsion based on Cocamide DEA at different phase ratios. However, Dioctylamine, PEG 1000, and PEG 600 promote the monophase separation in separating the emulsion. Optimization of the microwave-assisted chemical demulsification using Face Centered Central Composite Design (FCCCD) under Response Surface Methodology found that Octylamine (1.5 vol.%) promotes a superior effect on demulsification rate of different types of emulsion, the exposure time (0.5-8) minutes and the MW power (270-360) watt were the most significant factors at different types of emulsion that consist with lower demulsifier utility, crude oil A emulsions needed higher MW power to separate the two phases.
