2 Introduction Dynamic Simulation has been always been a key tool for production of O&G in harsh environment because of the difficulty to build or implement changes in the process as well as a very high standard of operational procedure requiring highly qualified and trained operators and engineers. Dynamic Simulation will be of great help in the following areas: Verification for new project or before implementing changes in process/control system Training for operators and engineers Optimization of process to increase production and reduce emissions / 2 / 31-Jan-11

5 What is Dynamic Simulation Wikipedia: Dynamic simulation is the use of a computer program to model the time varying behavior of a system Virtual copy (called model ) of the real plant Each piece of equipment becomes a block Each block reproduces the same effect on inputs/outputs (chemically, thermodynamically and physically) Process values in real time or quicker: DYNAMIC / 5 / 31-Jan-11
