How does seasonal weather variations affect vapor recovery operations?

Seasonal weather variations significantly impact vapor recovery operations because these changes can alter the physical properties of vapors being recovered. Temperature fluctuations can influence the density, pressure, and volume of vapors, which in turn affects how effectively vapors can be captured and returned to the system during refueling operations or while managing emissions. For example, in warmer temperatures, vapors may expand and result in higher pressure, potentially leading to increased emissions if not properly managed. Conversely, in colder temperatures, vapors contract, which can hinder their recovery efficiency. This interplay between temperature and vapor characteristics is crucial for ensuring compliance with environmental regulations and maintaining operational efficiency in vapor recovery systems.

While other options suggest limited or no effects from weather variations, they do not fully account for the complexities involved in vapor recovery operations, particularly how vapors behave under different thermal conditions. This understanding is vital for those working in the field to adapt and optimize vapor recovery practices throughout the year.
