An Experimental Investigation of Water Effects on Asphaltene Surface Behavior through Interfacial Tension Measurements

Ramin Moghadasi; Jamshid Moghadasi; Shahin Kord

Volume 7, Issue 4 , October 2018, , Pages 45-58

https://doi.org/10.22050/ijogst.2018.108233.1422

Abstract
  As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact ...  Read More
