Air pollution is one of the problems faced by all countries around the world. In Indonesia, air pollution is mostly caused by exhaust gas of vehicles and industrials emission gas. POPKA factory which becomes one of the biggest industrial factories in Indonesia uses Heat Exchanger engine to cool down the emission of gas. Although the simulation oh Heat Exchanger has been widely used, it is considered as steady in under several conditions. Accordingly, these conditions produce less resemble with actual condition. Furthermore, the calculation method which is used does not give a high accuracy, therefore another method in calculating the formed mathematical modeling is necessarily employed. This research created a new model of calculation method to overcome the problems which could display the effectiveness of Heat Exchanger type intercooler in cooling down the residual materials of POPKA factory and could be used to manage the residual emission into the air. It is aided MATLAB software in calculation process, FLUENT and GAMBIT software in the stimulation, and Gauss-Seidel method to know the effectiveness of the calculation. © Published under licence by IOP Publishing Ltd.
