- Develop hands-on control experience using AspenTech’s Virtual Plant, while under the guidance of a seasoned process control engineer
- Bridge the gap from academic process control concepts to real-world control practice
- Workshops are based on a high-fidelity, 1st principles Virtual Plant – a dynamic simulation of an actual process. Students use an individual Virtual Plant to get hands‑on control experience in a classroom environment
- This course quickly teaches new control engineers essential process control concepts that have been traditionally learned on the job
