What is the primary purpose of vapor recovery systems in fueling operations?

• A. To increase fuel efficiency in engines
• B. To capture vapors displaced during the filling of tanks
• C. To monitor fuel quality during storage
• D. To enhance the speed of fueling operations

Answer: (B)

The primary purpose of vapor recovery systems in fueling operations is to capture vapors displaced during the filling of tanks. When fuel is pumped into a storage tank, it creates a displacement of air and fuel vapors. If these vapors are not managed and captured, they can escape into the atmosphere, contributing to air pollution and the greenhouse effect. Vapor recovery systems are designed specifically to collect these vapors and prevent them from being released, effectively reducing harmful emissions. This process not only helps protect the environment but also promotes safety by minimizing the risk of vapor ignition and subsequent fires. Thus, capturing displaced vapors is integral to the functionality and purpose of vapor recovery systems.
