Abstract

En un método y un aparato para recuperar químicos a partir de un material de lignina alcalino, el material de lignina alcalino (3) que comprende NaOH o KOH se precipita en presencia de un ácido en una etapa de precipitación (6) para formar una lignina precipitada (7), la lignina precipitada (7) se suministra a una etapa de separación (8) en donde una lignina purificada (9) se recupera y a partir de la cual al menos una fracción (10) que comprende Na o K se suministra a una etapa de cristalización (11).
