The application and research of dispersing in situ Nano-SiO(2) in polyether demulsifier TA1031

In order to enlarge the application range of nanomaterial and improve the demulsification performance of macromolecule polyether demulsifier, the nano-SiO(2) was dispersed in situ in polyether demulsifier TA1031 to form a new high efficiency demulsifier. The new demulsifier was analyzed by FTIR, SEM, rotational viscometer, and interfacial tension meter. The result showed that dispersing nano-SiO(2) in crude oil demulsifier would greatly improve the demulsification performance of the original demulsifier. When the ratio of silicon dioxide and TA1031 is 1:10 (mass ratio), the demulsification performance of the new demulsifier was the best, and the dehydration rate of emulsion increased about by 20%. Also the time of demulification and dehydration would be greatly shortened, and the demusification mechanism was preliminary analyzed.
