Phase Separation of Asphaltene Dissolved in Toluene Leads to Nuclei Formation Promoted by the Very Low Solubility of Fraction A1. Soluble Fraction A2 Hinders Nuclei Flocculation
Journal Title: Petroleum & Petrochemical Engineering Journal - Year 2017, Vol 1, Issue 3
Abstract
Sudden aggregation of asphaltenes in toluene at room conditions is the consequence of reaching solubility concentration (close to 90 mg L-1) of the very low soluble asphaltene component A1 [1-3]. Thus at concentrations close to about 90 mg L-1 solid phase separation occurs with formation of nuclei where although type A1 molecules prevail, the nuclei contain enough A2 type molecules to keep them in solution
