摘要

Enclosed Ground Flares (EGF) are increasingly being used, especially in proximity of densely populated areas, in order to reduce the impact of flaring in terms of noise, pollution, smoke and flame visibility. The downside is that they are also very sophisticated and expensive pieces of equipment, and have a limited capacity; therefore the traditional deterministic approach used in sizing the flare header is not appropriate. A new methodology for sizing EGFs is proposed, which combines the use of dynamic simulation and a reliability model. Rigorous dynamic simulation is used to evaluate the duration of relieving from each device connected to the flare header, and also to verify the concurrency of relieving events during emergencies caused by general failures. The reliability model is used to take account of the frequency of each upset, the variability in equipment hold-up and the probability that other layers of protection may reduce relief load or avoid relieving altogether. The result of the model are two functions showing the duration and number of events when a given flare capacity is exceeded. This methodology has been applied to an ethylene plant (750 kt/yr), maintaining the traditional elevated flare for peak demand during general emergencies. The application shows that the relief flow rate through the elevated flare can be reduced significantly if compared to the results of using a traditional approach.
