Abstract
método para aumentar a eficiência química de aditivos químicos em um sistema de fabricação de papel inclui as etapas de fornecer polpa-base espessa que compreende lignina solúvel, água de processo e pelo menos cerca de 2 % em peso de fibra celulósica com base no peso total da polpa-base espessa e adicionar pelo menos um polímero orgânico à polpa-base espessa para reduzir a quantidade de lignina solúvel na mesma. o polímero orgânico é escolhido dentre polímeros catiônicos, polímeros não iônicos e combinações dos mesmos.
