چکیده مقاله:
There are many ways to break the water oil emulsion but chemical demulsification, heat treatment, electrostatic demulsification are most used. Each of these methods has advantages and disadvantages. Recently the advantage of nanotechnology shown up in many operations nano-titania particles were synthesized by sol-gel method. The prepared samples were dispersed in a conventional chemical demulsifier to verify whether it can improve the separation process. The prepared nano-titania particles were analyzed by particle size analysis (PSA), X-ray diffraction (XRD), transmission electron microscopy (TEM), bottle test, electrostatic test, and standard IP77 method. The results specified the sample with the highest water separation performance and obviously revealed that it would effectively increase the demulsification efficiency to a value greater than 90% and it would also decrease the settling time required for efficient separation.
