This paper introduces brief ideas for "Simulation of heat exchanger under fouled
conditions" research which includes its background study, objectives, literature review,
research methodology, results, discussion, recommendation and conclusion. In the initial
part of this paper, the fouling characteristic is discussed based on the literature review.
Fouling in heat exchanger is one of the major challenge need to be encounter by all
industrial practitioner in plant especially in oil refinery plant. This problem had caused
plant to increased their capital and operational cost because of inaccurate prediction of
accumulation of fouling in the heat exchanger. This paper also quotes and discussed
some literature and research of a few scholars about the fouling model characteristic and
performance. In the methodology, the steps taken throughout the project is discussed
briefly. The modelling of crude preheat train and simulation done is explained. Next,
result and discussion for this project is analyzed. In the last part, a few recommendations
are proposed to enhance the project before the project is concluded
