Abstract

<p>The production of bleached softwood pulp had been reduced at Chuetsu Pulp & Paper, Takaoka mill because of the reduction of the bleached softwood usage in the paper machines. Due to this reason, the old existing bleach plant became too big for the required production, and the operating and the energy efficiency became lower. There was high maintenance cost with the old bleach plant, and the old bleach plant building （built in 51 years ago）did not have enough strength for big earthquake. In order to solve these issues, Chuetsu pulp & paper decided to build the new softwood bleaching plant at Takaoka mill. The operation of new plant was started in December, 2015.</p><p>The reasons for Chuetsu to select the equipment supplier to Andritz were；DD washer which has multiple stage washing and minimum required space, higher chemical and energy efficiency, and less working load on operators with start-up and shut-down.</p><p>There were various issues since the start of production. But the present operation has been stable with modifications and operation tuning.</p><p>For our future challenges, we are trying to improve the chemicals and energy consumption, and maximize the benefit with automatic brightness control.</p>
