Use of amine neutralized sulfonated polystyrenes for particle flocculation

摘要

A process for flocculating solid fines from a solution comprising said solid fine and an organic liquid which comprises the steps of: (a) adding with mixing about 5 to about 10,000 ppm of an unneutralized or neutralized sulfonated polystyrene to said solution; and (b) heating at about 25 DEG C. to about 350 DEG C. for about 1 to abou 45 minutes the mixture of said solution and said neutralized or unneutralized polystyrene.
