Effect of salt concentration on the phase separation of bitumen emulsions

[Display omitted] ► Different phase separation situations are observed at various salt concentrations. ► Salt screening effect is responsible for the increased phase separation. ► Density changes of aqueous phase are more crucial at high salt amounts. This work has studied pronouncedly different pha...
