1. Low molecular weight lignosulfonates recovery by nanofiltration / Estudo da recuperação de lignossulfonatos de baixa massa molar por nanofiltração
Membrane separation processes like ultrafiltration (UF) and nanofiltration (NF) are used in the pulp and paper industry to the recovery of several species present in the wood digest waste that are interesting to other applications as lignin, sugars and specially lignosulfonates, improving the recirculation of the water in the pulping process and the reductio

2. Avaliação da utilização de redes neuronais aplicadas a processos quimicos
This work presents some important aspects when applying neural networks for chemicai process simulations. Neural networks are used in two different industrial processes providing a way of comparison of difficulties and potentialities for the application of this technique. Currently at Ripasa S/A. one of the largest paper industries in Brazil, the raw materia
