Summary for the CC25 example simulation

This example shows how you can use AVEVA Process Simulation to design and optimize the dimethyl ether (DME) production process shown in Figure 1. The focus of this exercise is to minimize the overall operating cost associated with the process by adjusting a variety of specifications. Operating cost optimization is critical for existing plants that plan to reduce overall expenses and maximize their profits. While capital expenses are an important consideration in the initial plant design, operating costs present an opportunity for continuous optimization long after plant startup and commissioning. The objectives of this simulation are to:

• Design a process to produce 10 t/h of DME through the dehydration of methanol

• Demonstrate how you can extend parent equipment models to use default operating cost submodels

• Demonstrate how you can use AVEVA Process Simulation for simultaneous optimization of multiple process specifications

• Minimize the operating cost associated with the process
