Which two contaminants must vapor recovery systems be designed to handle?

• A. Heavy metals and organic phosphates
• B. Hydrocarbons and other volatile organic compounds (VOCs)
• C. Radon and Chlorofluorocarbons
• D. Ammonia and Sulfur dioxide

Answer: (B)

Vapor recovery systems are specifically designed to capture and manage emissions that include hydrocarbons and other volatile organic compounds (VOCs). Hydrocarbons are a significant concern in many industrial processes, particularly in petroleum and chemical operations, where they are prevalent as both by-products and raw materials. VOCs are also critical targets for vapor recovery due to their potential to contribute to air pollution and the formation of ground-level ozone, which can have detrimental effects on health and the environment.

The design of these systems focuses on effectively reducing emissions of these substances, thereby enhancing air quality and ensuring compliance with environmental regulations. This specialization is crucial because managing VOCs and hydrocarbons directly addresses issues related to smog formation and potential health hazards to the population. Consequently, vapor recovery systems play a vital role in mitigating these risks and contributing to a safer, cleaner environment.
