What is the goal of vapor recovery systems in fuel dispensing?

To improve fuel flow
To minimize fuel loss to the environment
To reduce the cost of fuel
To increase storage capacity

The correct answer is: To minimize fuel loss to the environment

The goal of vapor recovery systems in fuel dispensing is primarily to minimize fuel loss to the environment. These systems capture fuel vapors that would otherwise escape into the atmosphere during the refueling process. When fuel is dispensed, air enters the tank to replace the liquid fuel being drawn out. This air displacement can lead to the release of volatile organic compounds (VOCs) and other harmful emissions into the air. By capturing and recovering these vapors, vapor recovery systems help to reduce air pollution and mitigate potential environmental impacts associated with fuel dispensing. In addition to their environmental benefits, these systems also contribute to safety by reducing the likelihood of explosion hazards posed by flammable vapors. While some might think that improving fuel flow, reducing costs, or increasing storage capacity could be primary concerns, these aspects are not the main objectives of vapor recovery systems, which specifically target air quality and environmental protection.
