What is the purpose of a vapor recovery system in a tanker?

The purpose of a vapor recovery system in a tanker is to prevent vapor loss during loading and unloading. This system is designed to capture and contain vapors that might otherwise escape into the atmosphere when the tanker is filled with liquid fuel or other volatile liquids. By doing so, it helps reduce air pollution and prevents the emission of harmful substances, which is essential for compliance with environmental regulations.

Vapor recovery systems work by directing vapors back into the tanker or to a recovery system where they can be processed or reused, thereby minimizing waste and maximizing efficiency. This mechanism is crucial not only for regulatory compliance but also for ensuring the safety of both the vehicle and the surrounding environment. In essence, the vapor recovery system plays a vital role in protecting air quality and reducing the risks associated with flammable vapors.
