Abstract
Patente de Invenção:<B>"PROCESSO DE DESSALINIZAçãO DE ALCATRãO CONTENDO FENOL"<D>. Um processo de dessalinização de alcatrão, no qual o alcatrão contendo sais é misturado com ácido ortofosfórico aquoso diluído em um processo em batelada ou contínuo, deixado sedimentar em duas fases, uma fase orgânica e uma fase aquosa contendo a maior parte dos sais, que é depois removida da fase orgânica. O processo remove um alto percentual dos sais do alcatrão e reduz a incrustação e a corrosão do equipamento a jusante.
