摘要

The first European full-scale partial borale autocausticizing trial commenced in November 2002 at the Stora Enso Norrsundet mill and has been running continuously and successfully since that time. The objective was to off-load the lime kilns and reduce the amount of fresh purchased lime and subsequent disposal costs. The total lime requirement has been reduced by about 7% while the autocausticizing level has been typically 9-11% over this period. Overall, the presence of sodium borate in the liquors had little effect on the mill operations and the pulp properties and quality were unaffected. There is some indication that borates may enhance the pulp yield.
