摘要：

The destabilization of crude oil emulsions by polyoxyethylene nonylphenels as inhibilop has been investigated at water-to-oil volume ratio of 1: 1, as 4 function of the HLB (hydrophilie-lipophilic balance) and concentration, The results show that the stability of crude oil emulsion begins to level off after a critical surfactant concentration. which seems to correspond to their critical micelle concentration (CIVIC), A stability minimum was found after the stability plateau region, which corresponds to the inversion of emulsion from W/O to O/W. Furthermore, the inhibitor with HLB - 14.2 has the highest efficiency for demulsification with the highest separation rate and the lowest inversion point, Whereas inhibitors with higher HLB are less effective, which may be due to the network formation by their very long oxyethyl headgroups and interactions with indigenous components of the crude oil,
