Modelling of Olefin Units by Engineering-Short Cut Correlations

Due to the importance of olefin units in the country and their complexity, optimization the operating & productivity conditions for these big plants seems very important. Since modelling and simulation some parts of the plant need complex mathematical relations and equations, so usage a simple and accurate method will be very useful. Practically, by using this method, a lot of design and operating parameters can be studied and commented about changes and optimizations. In this research study and modelling of olefin plant of Jam Petrochemical Complex which is the world's largest olefin unit, has been studied. Cooling and separation units modelled and simulated by relationships and methods of estimation and approximation (Rules of thumb) and it's results provided. Finally, further evaluation of this technique, was examined by six different operating conditions and calculations performed by these relationships. Results in many cases was acceptable & close to the design conditions.
