Vapor return systems prevent LNG vapors from escaping into the atmosphere during fueling. Vapors are captured and redirected back into the storage tank to maintain system balance.
Control valves and sensors regulate pressure during this process, ensuring that liquid LNG flows smoothly while vapor is safely recovered. This minimizes fuel loss and prevents overpressure in hoses.
Effective vapor management enhances safety, reduces environmental impact, and maintains accurate fuel measurement at the station.
