摘要:
The effects of crude oil acid number and brine concentration on the interfacial behavior of caustic/crude oil systems were investigated. The effect of increased brine concentration was generally to increase the minimum interfacial tension (IFT) while low IFT values were retained for longer periods of time. Varying the crude oil acid number caused the shape of the IFT versus time curve to change, while the minimum IFT remained constant. These combined results imply that Lagmuir and not Henry soption (adsorption/desorption) kinetics were operative
