| Abstract: | The influence of natural surfactants,such as asphaltenes,resins,solid particles and naphthene,on the stability of the water-in-crude oil emulsion are summari zed.The mechanism of crude oil′s demulsification is discussed,as well as the re lationships of the composition,HLB value,amount and combination of the demu lsifier to the demulsifying dehydration of crude oil.Several series of demulsif iers employed popularly inland nowadays are presented. |
