Abstract

The effect of molecular weight of polyester based de-emulsifiers on the de-elmulsification of Nigerian crude has been carried out. It was observed that initially, as the molecular weight of the polyesters (de-emulsifiers) increased, there was a corresponding fourth order polynomial increase in its performance when they were used to screen the Nigerian Crude Oil Emulsion (NCOE). It was further observed that beyond a molecular weight value of 7500g/mol it tended towards an asymptote at 30.6% performance. Beyond this point, further increase in the molecular weight of the de-emulsifier did not produce any significant increase in performance on the de-emulsification process of the NCOE. The performance of the de-emulsifiers also increases as the time of de-emulsification increases. For all the de-emulsifier samples, performance was highest after 10 minutes.
