BOG recovery in LNG refueling stations
Thread Content
Can the gas recovered from BOG in LNG refueling stations be directly pressurized and fed into the municipal natural gas network, with settlement with the gas company carried out through flow meters?
The gas recovered from BOG (Boiled Off Gas) at LNG refueling stations can be fed into the municipal natural gas network after pressure regulation. However, trading settlements with gas companies using flow meters require analysis based on specific circumstances. In some areas, the natural gas recovered from BOG can be used directly for internal consumption at gas filling stations, without the need for any transactions with gas companies. However, if you wish to sell the natural gas recovered from BOG to gas companies, you need to contact local gas companies to understand the relevant policies and requirements, in order to determine whether trade settlement can be carried out through flow meters. .
Floor 2 explained it in great detail. Using a return pipeline for the BOG at gas stations is relatively more economical (compared to compression mechanism cooling recovery).
The quality of the BOG from the gas station meets the standards of commercial gas, and there are pipeline networks in the vicinity that can be connected to, with pressures higher than those of those networks; therefore it should be possible. But if it’s a long distance, calculations are needed; building a pipeline in the urban area is quite troublesome.
