Abstract

Iwakuni Mill and Otake Mill in Nippon Paper Industries are located adjacent to each other. They needed to reorganize the production structure of pulp and paper for the purpose of recovering profitability.<BR>As one of the measure of this, we tried to make Kraft Pulp more competitive by shutting down the production of pulp at Otake Mill permanently, consolidating their production into Iwakuni Mill.<BR>For this reason, it has become more important to produce pulp stably. To achieve this, there was priority issue―`insufficient capacity of recausticizing process' to be solved. Especially capacity of hot lime production in kiln was bottleneck in our recausticizing process when we make up enough white liquor for two digesters in full swing. To increase hot lime production, we have modified the process and optimized operating condition and utilized add―on chemical. And then we have finally achieved to produce sufficient white liquor and debottleneck Kraft Pulp production.
