Abstract

<p>The demand for paper has significantly dropped after the Lehman collapse in 2009. That was why Yufutsu Mill had to halt the operations of Paper Machine No.1. It decreased the amount of the KP production and increased the energy consumption rate in the KP process. The accumulation of small improvement projects was not effective enough to get it back to pre-shutdown level. In this study, notable reduction of the steam consumption rate in the KP bleaching process, which was considerably affected by the production curtailment, was observed without any large capital investments, as a result of three measures：optimization of hot water usage, efficiency improvement in hot water generation, and drastic changes in exhaust heat recovery. This report describes these three measures.</p>
