Abstract
Refinery crude preheat
train (CPHT) is prone to fouling and ageing effects due to the complexity of
processed crude feedstock preheated prior to distillation. This results in
compromised performance efficiency of crude preheat trains.
To restore performance, optimal scheduling
cleaning operations are required. Authors review the subject of fouling/ageing
control and mitigation in crude preheat train network using an optimal
scheduling cleaning approach. They outline three optimization techniques/models,
including Mathematical Models; Artificial Intelligence (AI) Models; and
Heuristic Techniques.
