How can ambient air temperature influence vapor recovery performance?

The influence of ambient air temperature on vapor recovery performance is primarily related to how temperature affects vapor pressure. As temperature increases, so does the vapor pressure of the liquids being handled, which increases the amount of vapor that can be recovered. This means that during higher temperature conditions, there is a greater propensity for vapors to escape from the liquid product, and therefore, the vapor recovery system will need to be more efficient to handle the increased volume of vapors produced.

This relationship indicates that higher temperatures facilitate a more dynamic environment for vapor recovery systems to operate, ultimately enhancing their effectiveness in controlling emissions.

In contrast, lower temperatures generally lead to reduced vapor pressure, which can result in lesser recovery rates. The other choices either misrepresent the influence of temperature on vapor recovery or ignore the broader implications, such as the role humidity plays in vapor recovery, making them less relevant to the specific question about ambient air temperature's impact on performance.
