Dynamics mode for the AA3 example simulation

We use Dynamics mode to study the compositional profile during the adsorption cycles.

Each pressure swing adsorption (PSA) cycle involves the following four steps:

1. Pressurization: Pressurize Bed 1 and vent Bed 2.

2. Production: Produce high-purity oxygen from Bed 1 and continue to vent Bed 2.

3. Blowdown: Pressurize Bed 2 and vent Bed 1.

4. Purge: Produce high-purity oxygen from Bed 2 and continue to vent Bed 1.

We provide respective scenarios for each step. The following images illustrate the valve settings specific to each step, where green indicates a fully opened valve, red indicates a fully closed valve, and yellow indicates a 50% opening position for the valve.

We also provide a scenario that runs a full cycle (that is, all four steps), a scenario that runs five cycles, and a scenario that runs ten cycles. See the following section for more information.
