Metodologia de manutenção centrada em confiabilidade aplicada a sistema de dessufurização de gases

Abstract

Nowadays, the industrial sector have to support a great demanding for society due to a quality of the product and delivery speed. Its makes the industrial plants operate, in most the time, on its operational limits. This fact create a great challenge to the maintenance crews, because their must to provide availability guarantees of the equipment. The Reability Centred Maintenance (RCM) is a maintenance technique based on the equipments function preservation, therefore, beyond it make possible to achieve better availability and confidence rates, it proposes to obtain a better maintenance cost-benefit. This monograph presents many successful cases with RCM application and proposes to introduce a overview of the principal authors and consultants. Moreover, it is applied a RCM technique in a desulfurization gases system to create a new maintenance plan. As a result, it was created a maintenance program to whole system of gases desulfurization and it was analyzed more than sixty equipments and it was created eighty six maintenance tasks.
