Summary for the A8 example simulation

This example shows how you can use AVEVA Process Simulation to model the cryogenic air separation plant shown in Figure 1. Because the primary use of nitrogen is to exclude oxygen, the nitrogen product must contain no more than 10 ppm of oxygen. Given this requirement, accurate thermodynamic calculations are crucial. AVEVA Process Simulation offers a variety of thermodynamic methods to choose from and allows for method customization to meet the requirements of even the most stringent processes. With the conceptual design presented in this example, we explore various business cases to give direction for subsequent detailed engineering. We investigate the impact of increasing the liquid oxygen throughput relative to the vapor oxygen product. The objectives of this simulation are to:

• Design an air separation plant that separates nitrogen, oxygen, and argon from an air stream.

• Demonstrate how to switch specifications to meet different design requirements.

• Develop scenarios in Process mode to investigate a variety of process cases prior to detailed engineering.
