What do vapor recovery systems primarily aim to recover?

Vapor recovery systems are designed primarily to capture vapor emissions that occur during the transfer of liquid fuels, such as gasoline, between storage tanks and vehicles. The process involves collecting the vapors that would otherwise be released into the atmosphere, which not only helps in reducing air pollution and greenhouse gas emissions but also promotes energy efficiency by recovering potentially usable fuel vapors.

By focusing on vapor emissions, these systems play a critical role in environmental protection and regulatory compliance, as vapor emissions can contribute to smog formation and other air quality issues. Therefore, the correct emphasis on vapor emissions reflects the primary function of these systems in mitigating environmental impacts and optimizing fuel use during transfer operations.
