Corrosion testing was performed in white, green, and black liquors from a kraft mill. The liquors were modified in composition to simulate conditions of high (40%)sulfidity and low (30%)sulfidity, and then heated in laboratory autoclaves to the temperatures of the respective tanks from which the samples were taken. Specimens of carbon and stainless steels were exposed under “free” corrosion potential conditions, and their corrosion rates determined from weight loss measurements. In white, green, 45% solids black, and flash tank liquors, active corrosion rates for the carbon steels were typically 20 to 75% higher in the higher sulfidity liquors. In 15%solids weak black liquor there was no appreciable difference in corrosion rates, with carbon steels remaining passive in both low and high sulfidity. In 26% solids intermediate black liquor there were large increases in the corrosion rates of carbon steel between low and high sulphidity liquors, resulting from a change from passive to active conditions. Stainless steels UNS S30403, S32304, and S31803 had very low corrosion rates in all the liquors tested, regardless of sultidity. Kevwords: alkaline liquors, anodic protection, austenitic stainless steel, black liquor, carbon steel, corrosion testing, digesters, duplex stainless steel, flash tanks, green liquor, pulp and paper, storage tanks, white liquor.
