Abstract
Kasugai mill, Oji Paper, has started the operation in 1952, as fine paper making plant which introduced Japan’s first commercial Kamyr-type continuous digester and multi stage bleach line. It has now taken the lead in Oji Paper as the integrated pulp and paper plant with producing several paper grades, through a couple of new installation, reinforcement, replacement and modification.
Recently, Japanese paper industry has been in a tough situation, since the domestic demand of paper has reduced and the imported paper has increased. In such a situation, the replacement including S&B has been severely restricted, and the maintenance on existing facilities has become the key in managing plant operation. In our mill, equipment failure led to production loss had been recently increased because numerous facilities might be deteriorated by long term operation.
The production losses by equipment failure and mistake in operation have not an impact on business productivity but also safety and environment aspect, so that a couple of countermeasure have been scheduled with based on analysis of production loss cases.
The five cases of deteriorated equipment failure are reported in this article with cause and solution.
