摘要:
A method and apparatus is provided which will provide over-pressure protection for an underground storage cavern by reducing the pressure of a pressurized gas stream originating from the an underground storage cavern to form a lower pressure gas stream, monitoring the pressure of a lower pressure gas stream and stopping the flow of the lower pressure gas stream to the pipeline should the pressure of the lower pressure gas stream exceed a threshold value.
