Summary for the AA2 example simulation

This example shows how you can use AVEVA Process Simulation to design the hydrogen liquefaction process shown in Figure 1. For many years, the aerospace industry has used liquid hydrogen as a rocket propellant. Recently, researchers in fuel cell technologies have explored the use of liquid hydrogen as a fuel. Hydrogen also plays an important role in semiconductor manufacturing processes. As hydrogen gas cools and liquefies, the ratio of its ortho to para spin isomers decreases. AVEVA Process Simulation models this process by using a custom equilibrium reaction model in the fluid. The objectives of this simulation are to:

• Design a hydrogen liquefaction process.

• Show how you can write a fluid reaction submodel by using existing experimental data.

• Demonstrate the Joule-Thomson effect in a control valve.
