Abstract

Un método para recuperar material solvente orgánico de un líquido hidrófilo derivado de operaciones de tratamiento de excesos de pintura rociados en elcual la emulsión de solvente en agua contiene inicialmente 1-50% por peso de un líquidoorgán ico que tiene un punto de ebullición de por lo menos150*C, una presión de vapor inferior a 0,6 Torr a 20*C, y agua, y el líquido hidrófilo gastado contiene adicionalmente material sólido de pinturaderivado del tratamiento de excesos depintura por rociado en el cual el método de recuperación incluye los pasos de: a) retirar el líquido hidrófilo gastadoo una parte del mismo de la cabina de pintura; b) alimentar la emulsión de solvente en agua gastada al interior de un tanquede reacción, operando eltanque de reacción a una presión a 100 mm/Hg y a una temperatura suficiente para volatilizar el componente líquido del líquido hidrófilo; y c) separaruna porción de dicho líquido orgánico volatilizado del líquidohidrófilo gasta do después de introducir el líquido hidrófilo gastado en el tanquede reacción. El componente líquido orgánico se selecciona del grupo que incluye alcolésteres secundarios, derivados de alcolésteressecundarios,dialquildiésteres de ácidos dibá sicos y n-metil pirrolidonas.
