Mathematical Modelling and Simulation of Petrochemical Processes

The main objectives of this project is to set up the process model for Propane,
C3H8 (Distillate) and Butane, C4H10 (Bottom) distillation column, to build up MATLAB
Simulink program for simulations of mentioned process and to analyze the process with
parameters change. From this project, student will also be able to learn about the current
crude oil distillation processes and the related factors that could improve the efficiency
of the output products which are the Top product and Bottom product. Refineries are
among the largest energy consumers in the chemical industries. It was evaluated that the
energy requirement for the crude oil distillation plant is an amount of fuel equivalent to
the 2% of the total crude processed. For this reason there is a great interest to identify
ways to improve the energy efficiency of the existing plants.
The scope of study is to use the MATLAB software to simulate the petroleum
distillation process base from the developed mathematical modeling done by fellow
researcher. Then, analysis will be conducted base from the simulation. Modifications on
the parameters of the simulation program could be done to improve the efficiency of the
output products.
The methodology of the project would first start with the research study on
current crude oil distillation processes and the mathematical modeling constructed. After
that, use the developed mathematical modeling to simulate the processes using
MATLAB software. Finally, analyze and modify the model to increase the efficiency of
the output products.
There are several findings up until this report was produced. One of it is related
with the design of the distillation column that could influence the percentage of the
output products. As the number of tray increases, the purity of the Top product will also
increases. But, there will be issues with the energy consume and economic cost. Besides,
changes in parameters give different effects on the output products. Thus proper
considerations need to be done for each situation.
