What is the primary purpose of vapor recovery systems?

The primary purpose of vapor recovery systems is to capture and recycle gasoline vapors during the refueling process, which plays a significant role in reducing harmful emissions into the atmosphere. These systems are designed to prevent the escape of volatile organic compounds (VOCs) that occur when gasoline is transferred from a storage tank to vehicles. By capturing these vapors and directing them back into the storage tank or a recovery system, vapor recovery systems effectively diminish the release of pollutants, contributing to cleaner air and compliance with environmental regulations.

Implementing such systems not only helps mitigate air quality issues but also enhances overall energy efficiency by recovering valuable fuel that would otherwise be wasted. Therefore, the correct answer highlights the primary function of vapor recovery systems in promoting environmental sustainability and public health by addressing air pollution associated with fuel handling practices.
