Bonus Report: LNG Developments

Use dynamic simulation for advanced LNG plant design

The work performed for the project shows that dynamic simulation can be an excellent tool for the support and verification of process design during the engineering, procurement and plant construction (EPC) stages.

Performing engineering studies with dynamic simulation is becoming a critical requirement for new liquefied natural gas (LNG) plants. Typically, the major target for such a study is the investigation and review of critical plant design elements, such as compressors, flares and boiler systems. Dynamic engineering studies can identify design changes that will significantly improve plant performance and the safety and reliability of plant operations. Furthermore, if such design changes are identified early, they can be implemented at a low cost and provide significant savings during a plant’s lifetime.1–3 LNG plant design is based on steady-state process simulation. This approach t
