Experimental strategy of application of fosfonatos in the kraft pulping and Bleaches TCF and ECF

Abstract

In this work is presented one experimental strategy for chelants applications in pulping and bleaching stages, Totally Chlorine Free (TCF) and Elementary Chlorine Free (ECF). The obtained results demonstrated that the combination of factorial designs with one Hierarchical Plan, that included intermediate decisions, possibilities the efficient experimental work since the optical point of obtained information an the investigation costs.
