摘要：
The present work focused on the environmentally friendly deep desalination of crude oil using ethylene glycol as the extraction solvent and quartz sand as the demulsifier. The effect of droplet size distribution in the emulsion on the dehydration results and desalination efficiency was investigated. Experimental results showed that the desalination efficiencies of Sarir and Basra crude oils were 93.3% and 90.0%, respectively. Furthermore, the desalination efficiency of Basra crude oil using ethylene glycol could be enhanced up to 96.7% by adding 30 g/L quartz sand with a particle size of 15 μm. Finally, 94% of the ethylene glycol and 86% of the quartz sand could be recovered from the emulsion. This process offers an alternative method to the deep desalination of crude oil.
