Abstract

La invención se refiere a un método y un aparato para separar un producto de ácido hidroxicarboxílico (33) a partir de una suspensión (31) que contiene ácido hidro-xicarboxílico formado como resultado de la hidrólisis (11) y la fermentación (12) de materia prima de naturaleza lignocelu-lósica (2). De acuerdo con la invención, la suspensión (31) que contiene ácido hi-droxicarboxílico es tratada mediante una separación en dos etapas (36a-b) para formar el producto de ácido hidroxicarbo-xílico (33), donde la separación en dos etapas consiste en una primera etapa de separación (36a) en la cual el agua (37) es separada a partir de la suspensión y una segunda etapa de separación (36b) en la cual el producto de ácido hidroxicar-boxílico (33) es separado a partir de la suspensión (32) de la cual se ha elimina-do agua, y el ácido hidroxicarboxílico (39,40) es añadido a la suspensión (32) antes de la segunda etapa de separación (36b) a fin de aumentar la concentración del ácido hidroxicarboxílico en la segun-da etapa. Asimismo, la invención se re-fiere al uso del ácido hidroxicarboxílico como agente concentrador.
