Abstract
Black liquor is an important by-product of the kraft process in the paper and pulp Industry. Black liquor is a complex solution consisting of various inorganic and organic chemicals. It can be very corrosive though the reasons have not yet been studied systematically. This article outlines the first set of experiments aimed at developing synthetic liquors that mimic the corrosivity of black liquor. The experiments involved the use of fractional factorial designs to study the large number of chemicals involved. SEM photomicrographs of some coupons exposed to synthetic liquors were found to have a similar corrosion morphology to coupons that had been exposed in real mill liquors.
