The preparation of a polyether demulsifier modified by nano-SiO 2 and the effect on asphaltenes and resins

In order to enlarge the range of applications of nanomaterials and improve the performance of macromolecular polymer demulsifier, nano-SiO 2 was integrated with polyether demulsifier TA1031 to form nanomodified demulsifier using an in situ synthesis method. Analysis of the polyether demulsifier modified by nano-SiO 2 was performed using transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy. The result showed that applying nanomaterials to crude oil demulsifier greatly improves the performance of the original demulsifier. When the ratio of nano-SiO 2 and TA1031 is 1:10, the performance of the nanomodified demulsifier was best, and the ratio of demulsification was improved by about 20%. The time of demulification and dewatering was also greatly shortened by about 30 min. The influence of nanomodified demulsifier on the asphaltenes and resins was studied by FTIR.
