Dynamics mode for the AA4 example simulation

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

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

1. Bed 1 produces while Bed 2 purges

2. Bed 1 pressurizes into Bed 2

3. Bed 1 vents while Bed 2 regenerates

4. Bed 1 vents while Bed 2 produces

5. Bed 1 purges while Bed 2 produces

6. Bed 2 pressurizes into Bed 1

7. Bed 2 vents while Bed 1 regenerates

8. Bed 2 vents while Bed 1 produces

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 30% (PV1 and PV2) or 50% (PCV) opening position for the valve.

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