Availability Estimations for Utilities in the Process Industry

Publiceringsår: 2010
Språk: Engelska
Dokumenttyp: Konferensbidrag


An important performance measure of a plant is the plant-availability. The higher availability the better, since a high availability implies a possibility for a large production volume and thereby an increased profit for the company. One way of increasing the plant-availability is by eliminating, or minimizing the effect of disturbances. The cause of a disturbance can be personnel, material or equipment, where material includes both raw materials and utilities.

The aim of this work is to increase the plant-availability by decreasing the effects of plant-wide disturbances caused by utilities. The first step is to determine the set of utilities that can be present at an industrial site, what disturbances these utilities can suffer, and how frequent and safety-critical these disturbances are. A later step will be to determine the effects on the plant-availability, and ways to decrease or eliminate these effects.
