summary
LNG gasification station
The urban gas gate station is the key equipment that enters the urban pipe network from the long-distance transmission pipeline. It is used at the downstream of the initial station or the upstream of the urban central pipe network. It has the functions of filtering heat tracing, pressure regulation, dosing, odorization, distribution, and remote telemetry/telecontrol.
technological process
The city gate station, storage and distribution station shall have the main functions of filtration, heat tracing, pressure regulation, metering, odorization, safe release, safe cut-off, automatic switching between trial line and standby line, etc. It is required to design multi main safety measures on the premise of ensuring accurate pressure regulation and flow metering to ensure the long-term and safety of gas use.
