Abstract:
Expenditures to improve process control infrastructure in pulp and paper mills should be analyzed and evaluated as rigorously as greenfield investments to optimize capital effectiveness. An approach to such an evaluation based on the economic impact of process control equipment reliability is presented. The procedure, called the control infrastructure health assessment (CIHA), is described and the results obtained for a particular case are discussed. Some data and the linkage to life cycle costing (LCC) are shared.
