Reactor design, process design, simulation and pinch analysis for styrene (monomer) production process from ethylene and benzene [.DOCX, .PDF]

A case study as an introduction to the Aspen PLUS and Aspen Energy Analyzer softwares.

A good file for introducing the design of chemical processes.

Introduction to the heat ex-changer network design by pinch method. 

All parts of designing a process in the oil, gas and petrochemical industries are carried out on styrene production process. 

The general steps in process design are as follows:

- Finding the different routes of synthesis of the desired substance. 

- Choosing the best route based on energy and economic considerations. 

- Finding kinetics of reactions and determining optimal conditions for reactor function. 

- Modeling and simulation the reactor system and determining the reactor output conditions (using Aspen PLUS).

- Selecting the best separation sequence method and designing the separation system to separate the main product from by products at the reactor outlet (Using Aspen PLUS). 

- Determine the streams that require heating or cooling and the design of the heat ex-changer network. 

- Determine pinch line and break loops in the initial design of the heat ex-changer network (using the Aspen Energy Analyzer). 

- Apply the final network of heat ex-changers to the simulated file in Aspen PLUS. 

In this project, the above steps have been applied to the styrene production process (one of the most important petrochemical products).
