The determination of operating fouling factors for individual exchangers is called rating. This is only the first step of an overall fouling monitoring and cleaning analysis apWhen combined with the need for plant data reconciliation
functionality, extensive spreadsheet macro programming is required to develop an
application that is reliable, accurate, and integrated into plant data systems. Commercially,
KBC’s PersimmonTM application is a long-established spreadsheet-based application that
has both rating and simulation capabilities specifically focused on cleaning benefit analysis
and automated linear and nonlinear data reconciliation capabilities.plication.
