Abstract
La invención se refiere a un método para recuperar HCl de una corriente gaseosa que contiene HCl en donde se suministra una corriente gaseosa que contiene HCl con una temperatura de -20 a 25°C a una unidad de absorción adiabática en donde se la hace entrar en contacto con agua como absorbente, resultando en la formación de una corriente gaseosa superior y un producto solución acuosa de HCl, en donde la temperatura de la corriente gaseosa superior es al menos 70°C y en donde el producto solución acuosa de HCl tiene una concentración de HCl en el rango de 5-20%p. Se prefiere que la corriente gaseosa que contiene HCl derive de un paso de hidrogenación en donde se hace reaccionar una alimentación que comprende ácido monocloroacético (MCA) y ácido dicloroacético (DCA) con hidrógeno para formar una corriente gaseosa que contiene HCl y una corriente de producto que comprende MCA y una cantidad reducida de DCA. La solución de HCl producida se diluye preferiblemente hasta una concentración de 1-8%p, y la solución diluida se utiliza como absorbente en un segundo paso de absorción, en donde se absorbe HCl de una corriente gaseosa adicional que contiene HCl para formar una segunda solución acuosa de HCl. La corriente gaseosa adicional que contiene HCl deriva preferiblemente de un paso de cloración en donde se hace reaccionar ácido acético con cloro, resultando en la formación de la corriente gaseosa adicional que contiene HCl y una alimentación que comprende ácido monocloroacético (MCA) y ácido dicloroacético (DCA).
