ABSTRACT: An on-line fouling monitor was employed to obtain over five million hours of data on fouling in recirculating cooling water heat exchangers. From these data a model was developed to predict cooling water heat exchanger fouling performance irrespective of water chemistry. The predictive index was subsequently applied to actual operating exchangers with excellent correlation. A Case study is presented demonstrating verification of the predictive index.
