Abstract
"MéTODO PARA SEPARAR E RECUPERAR UM TENSOATIVO". é descrito um método para recuperar e reempregar tensoativos Iónicos de soluções aquosas e dispersões/emulsões de água e hidrocarbonetos líquidos, pela adição de uma segunda fase polar, bem como um sal inorgânico que causa a preferida divisão do tensoativo ao prover uma fase de força iónica preferida para o tensoativo. Mais especificamente, o método aplica-se a recuperação de compostos modificadores/inibidores do crescimento de hidrato, compreendendo tensoativo catiónico, tal como, por exemplo, amónio, fosfónio e compostos alquilados de sulfónio, que foram adicionados a um efluente fluido de um poço de produção de hidrocarboneto, o efluente incluindo água, composto inibidor de hidrato, pelo menos um solvente polar adicional e sal inorgânico, por um método compreendendo adicionar suficientes íons adicionais de sal inorgânico e, se necessário, um álcool/glicol ao efluente para formar uma segunda fase polar, menos polar do que a fase aquosa, dentro da qual o inibidor de hidrato pode então se dissolver e ser separado da salmoura.
