Vapor recovery nozzles are devices attached to gas pumps that capture and redirect gasoline vapors, preventing them from escaping into the atmosphere during the refueling of automobiles. The targeted pollutant of vapor recovery nozzles is primarily gasoline vapor, which evaporates and escapes into the air when gasoline is dispensed, contributing to smog and air pollution. By capturing and returning these vapors to the storage tank, vapor recovery nozzles help reduce emissions of volatile organic compounds (VOCs) and other harmful pollutants, such as benzene, protecting both public health and the environment.

What You'll Learn
Vapor recovery nozzles are an air pollution control device
Vapor recovery nozzles capture these vapours and redirect them back into the storage tank, reducing emissions of volatile organic compounds (VOCs) and other pollutants. This helps to protect public health and the environment. They are especially useful in reducing ground-level ozone, which is a major contributor to smog. The nozzle is designed to fit snugly into the vehicle's fuel tank opening. As fuel flows, vapour collects in a chamber of the nozzle, which then channels the vapours back to the underground storage tank, preventing their release into the atmosphere.
In the United States, the use of vapor recovery systems is regulated by the Environmental Protection Agency (EPA), which enforces standards to reduce volatile organic compounds and other pollutants. The EPA has set emission standards for cars and limits for the release of air pollutants from power plants and factories, effectively reducing NOx and SO2 levels in the atmosphere. This has helped to reduce the effects of acid rain.
Vapor recovery nozzles are also beneficial in terms of conservation, as they reduce the amount of gasoline that is wasted during the refuelling process. However, their primary purpose remains to comply with environmental regulations and reduce air pollution. The development of new, more effective, and low-maintenance vapor recovery technologies is an ongoing process to improve the feasibility and compliance of these nozzles with regulatory standards.
