What is the purpose of the vapor recovery system in fuel dispensing?

The purpose of the vapor recovery system in fuel dispensing is to recover vapors during refueling to prevent emissions. When fuel is pumped into a vehicle, the liquid fuel displaces vapors in the tank. Without a recovery system, these vapors would escape into the atmosphere, contributing to air pollution and smog formation. The vapor recovery system captures these vapors and routes them back to the storage tank or a recovery unit, thereby minimizing the release of volatile organic compounds (VOCs) and ensuring compliance with environmental regulations. By effectively managing these vapors, the system not only protects the environment but also improves overall air quality around fueling stations.

The other choices do not accurately depict the primary function of vapor recovery systems. While minimizing fuel spills is important and can be a secondary benefit to the system, it is not the core purpose. Fuel temperature management and increasing fuel flow rate are unrelated to the fundamental goal of vapor recovery, which is to mitigate emissions during the fueling process.
