After the loading and unloading of liquefied petroleum gas is completed, before the loading and unloading arm is disassembled, the pipeline uses nitrogen gas to purge the residual petroleum gas to remove the flare; during the maintenance of the transmission system, the petroleum gas in the pipeline is also repeatedly purged and replaced with nitrogen gas before closing the storage tank outlet The valve is overhauled, which can greatly reduce the pollution of the surrounding environment caused by the discharge of petroleum gas due to loading, unloading, and overhaul.
