A General Method for Handling Disturbances on Utilities in the Process Industry

Lindholm, Anna LU ; Carlsson, Hampus and Johnsson, Charlotta LU (2011) 18th IFAC World Congress, 2011
Abstract
Utilities, such as steam or cooling water, have shown to play an important role within the process industry, since a malfunctioning utility is a plant-wide disturbance that can lead to large revenue losses due to reduced production quantities. This work focuses on identifying disturbances on utilities that give economical consequences. Measures of utility availability and area availability are introduced and used for estimating the ratio of disturbances on utilities. A generic method for handling disturbances on utilities is presented, which could be applied using site models of different level of detail. Some modeling approaches for modeling a site are described and the framework of the general method is demonstrated with a case study... (More)
