What factor can significantly affect vapor recovery performance at gas stations?

Temperature variations are a critical factor impacting vapor recovery performance at gas stations. When temperatures fluctuate, the density and volatility of fuels can change, leading to alterations in the behavior of vapors generated during fuel dispensing.

Higher temperatures typically increase vapor pressure, causing an increase in vapor generation, which can overwhelm the vapor recovery system if it is not designed to handle such conditions. Conversely, lower temperatures may reduce vapor pressure and could lead to more liquid being captured, potentially leading to less efficient vapor recovery.

The design and operation of vapor recovery systems must consider these temperature fluctuations to function effectively and meet regulatory requirements for emissions control. Effective vapor recovery is essential not only for compliance but also for protecting the environment and improving air quality.
