Optimization of BOG management during LNG unloading with dynamic simulation

In LNG receiving terminals, the dynamic nature of boiloff gas (BOG) generation in the unloading process can be difficult to understand, and BOG management can be challenging. Dynamic simulation has been used in a few limited studies in this field, but a systematic approach is lacking for conducting simulations, data collection and analysis. In this study, dynamic simulation, experiments and analysis are used to model the entire LNG unloading process, to collect and analyze experimental data, to gain insights into system behavior and to optimize the unloading process. This optimization is performed with respect to two important decision variables—the recirculation flowrate and the bypass flo
