DEVELOPMENT OF A MODEL FOR ESTIMATION OF FOULING IN SHELL AND TUBE HEAT EXCHANGERS

Shell and tube condensers are a common feature of many chemical processes, including distillation, reactor effluent separation, and steam cycle power generation. The use of cooling water in condensers makes fouling an important concern in the long-term operation of these processes. This project used numerical methods to model shell and tube heat exchangers for the design of a soft sensor. This model can be used by process engineers for performance monitoring when scheduling required cleaning time and estimating future run length.
