What challenge can arise from cold weather in vapor recovery systems?

In vapor recovery systems, cold weather can lead to challenges primarily associated with the behavior of gases and liquids. When temperatures drop, the vapor pressure of gasoline also decreases. This reduced vapor pressure can cause liquid to condense, resulting in an accumulation of liquid in the vapor lines. This liquid buildup can obstruct the flow of vapors and inhibit the effective recovery of gases, ultimately compromising the efficiency of the vapor recovery system.

Understanding this dynamic is crucial for technicians and operators as they work to maintain optimal system performance. Adverse effects, such as the obstruction caused by liquid buildup, can lead to more significant operational issues if not addressed, such as vapor leaks or increased emissions. Therefore, recognizing and mitigating the effects of cold weather on vapor recovery systems is an essential part of maintaining effective environmental compliance and ensuring the systems function correctly.
