What common contaminants must be removed from captured vapors?

The selection of water, oil, and particulates as common contaminants that need to be removed from captured vapors is essential to ensuring the proper function of vapor recovery systems. These contaminants can cause several issues, including corrosion, operational inefficiencies, and impact on the effectiveness of the vapor recovery process.

Water can lead to the formation of emulsions, which may hinder the separation and recovery of vapors. Oil can contaminate the recovery system, rendering it less effective, since it may coalesce with vapors and alter their chemical properties. Particulates, including dust and other solid particles, can clog filters and other components within the system, leading to increased maintenance requirements and decreased efficiency.

In the context of vapor recovery, it is crucial to maintain the purity of the vapor stream to comply with environmental regulations and achieve optimal recovery rates. By removing these common contaminants, the system operates more effectively, ensuring that it captures the maximum amount of vapors while minimizing emissions and environmental impact. This emphasizes the importance of proper pre-treatment of captured vapors before they enter storage or processing systems.
