Summary for the G2 example simulation

This example demonstrates how you can use AVEVA Process Simulation to design a deethanizer that separates ethane from a mixture of light hydrocarbons. We provide two simulations for this example. These simulations illustrate how to approach the separation at different stages of the design process.

• G2 - Deethanizer

  A conceptual design that uses only Process mode within AVEVA Process Simulation.

• G2 - Deethanizer Detailed Engineering

  A continuation of the conceptual design that includes additional process details. This simulation provides both the detailed steady-state equipment design in Process mode and a validation of the process control strategy in Dynamics mode.

These simulations meet the following objectives:

• Design a deethanizer that separates ethane from a light hydrocarbon mixture into products with required purity.

• Switch specifications to meet different design requirements.

• Migrate a conceptual design to a detailed design simulation by using AVEVA Process Simulation.

• Validate the process control strategy for the separation.

The following figures show the two different simulations. Figure 1 shows the deethanizer process as a conceptual design model (G2 - Deethanizer). Figure 2 shows the detailed process design model (G2 - Deethanizer Detailed Engineering).

Figure 2: Detailed engineering model and dynamic simulation

Within AVEVA Process Simulation, we use the Column model from the Process library to address both the conceptual and detailed engineering shown in these examples. For conceptual engineering, the Column model integrates both a condenser and reboiler for a simplified engineering approach. We then use the built-in column features to extend the conceptual design to a detailed engineering design with external condenser and reboiler models. Both simulations provide the same output in Process mode, but the detailed engineering simulation provides additional details in Fluid Flow and Dynamics modes.
