Abstract
Nano-SiO₂ was integrated with polyether demulsifier TA1031 to form nanomodified demulsifier using an in situ synthesis method, in order to enlarge the range of applications of nanomaterials and improve the performance of macromolecular polymer demulsifier.
Results revealed that applying nanomaterials to a crude oil demulsifier significantly improves the performance of the original demulsifier.  Performance of the nanomodified demulsifier was best when the ratio of nano-SiO₂ and TA1031 is 1:10. The time of demulification and dewatering was significantly reduced, as well.
