Abstract

En un procedimiento para aislar lignina de una corriente de proceso alcalino, en particular, licor negro espesado, la corriente de proceso alcalino se introduce continuamente en un área inferior de, al menos, un reactor de circulación (1) que presenta dos zonas de reactor dispuestas concéntricamente; en donde se selecciona un nivel de líquido (10) de la corrientede proceso alcalino en el interior de, al menos, un reactor de circulación (1) que se encuentre, esencialmente, en un nivel con un extremo superior (7) de, al menos, una zona interior tubular (6) del reactor; donde un gas que contiene CO2 se insufla continuamente desde abajo hacia, al menos, una zona interior tubular (6) del reactor de, al menos, un reactor de circulación (1); donde se absorbe el gas que contiene CO2 en, al menos, una zona interior tubular (6) del reactor de la corrientedel proceso alcalino y se retira el gas residual junto con las cantidades residuales de CO2 en la parte superior de, al menos, un reactor de circulación (1); donde el procedimiento se lleva a cabo a presión ambiente, en particular, 1 atm, y donde se extrae el licor negro espesado y pobre en lignina junto con la lignina precipitada contenida en el mismo, en caso necesario, después de dejarlo decantar en el fondo de, al menos, un reactor de circulación (1).
