F-18 Designing Heat Exchangers for Fouling Service: Cooling Water and Crude Oil Preheat

C. A. Bennett

This report summarizes the fouling propensity of some common fluids, the types of fouling, and techniques for mitigating them. In addition, when designing heat exchangers for fouling service, engineers must evaluate not only general fouling considerations but also the financial impact of fouling and potential mitigation techniques. Last, heat exchanger design margin metrics are reviewed and alternatives to Tubular Exchanger Manufacturers Association (TEMA) fouling factors for cooling water and heavy liquid hydrocarbon mixtures (including crude oil) are presented.

By using the extensive reference list provided, thermal engineers can identify other resources on the topic, refine their design approach, and justify the recommended techniques.
