A Comparative Study on Emulsion Demulsification by Microwave Radiation and Conventional Heating

Abdurahman H. Nour and Rosli, M. Yunus

Abstract: A heavy crude oil has been increasingly important sources of hydrocarbons in many parts of the world, in which transportation of this heavy crude oil to refinery can be a problem. During the lifting, transportation and processing of oil, frequently emulsions either water-in-oil or oil-in-water are created. Formation of these emulsions during oil production is a costly problem, both in terms of chemicals used and due to production losses. The traditional methods of eliminating these emulsions, utilize high heat and chemicals, which forces the emulsion to separate into water, hydrocarbon and solids. This study investigates comparatively on emulsion demulsification between the conventional and microwave heating. Two types of different crude oils were used as samples for the study. The oils are denoted as A and B. crude oils were synthesized in the laboratory. The water to oil ratio was varied from 30-50: 70-50. In company the two heating methods, the heating duration was varied from 5 to 60 min for conventional heating method, while for microwave heating, the duration was varied from 30 sec to 4 min. Microwave demulsification is primarily due to heating. However, the comparisons between the microwave heating and conventional heating show that they are different. The microwave induced molecular rotations also play a role. Molecular rotations can reduce zeta potential which suspends water droplets and solid particles in an emulsion.
