What should be considered when sizing a vapor recovery system?

When sizing a vapor recovery system, it is essential to take into account the tank size, flow rate, and throughput of the fuel dispensing site. This comprehensive approach ensures that the system can effectively capture and manage vapors generated during the fueling process.

The tank size is critical because it determines the volume of fuel that can potentially create vapors. Larger tanks may produce more vapors, requiring a more robust recovery system. The flow rate, which is the speed at which fuel is dispensed, influences how quickly vapors are generated; higher flow rates typically lead to increased vapor production. Moreover, the throughput of the fuel dispensing site—which refers to the total volume of fuel dispensed over a set period—affects how much vapor needs to be captured. Thus, all these factors must be considered together to ensure the vapor recovery system operates efficiently, reducing emissions and complying with environmental regulations.

While the other factors listed may have relevance in specific contexts, they are not primary considerations for sizing a vapor recovery system. For instance, while the installation site's location may impact environmental regulations or logistical aspects, it does not directly influence the system's capacity to manage vapor. Similarly, although the type of fuel can affect vapor characteristics, it is the combination of tank size, flow
