AI Technical Summary

Technical Problem

Existing VOCs recovery and treatment technologies have flaws in their safety gas replenishment control strategies, which can easily lead to secondary safety risks. Furthermore, they fail to consider the uneven oxygen distribution within the tank, resulting in frequent equipment starts and increased energy consumption, and thus cannot guarantee the overall safety and economy of the operating environment inside the tank.

Method used

Employing multi-stage separation and safety control technology, the system acquires the gas pressure and oxygen concentration values ​​within the purified oil tank. Combining these values ​​with the oxygen partial pressure, it classifies various operating conditions and uses a multi-strategy safety gas replenishment module for precise control. This avoids frequent starts and exceeding safety parameter limits due to localized oxygen accumulation, ensuring the stability of gas pressure and oxygen concentration.

Benefits of technology

It achieves efficient recovery and resource utilization of VOCs, improves equipment lifespan, reduces energy consumption, and ensures safe and stable operation of the system, resulting in significant environmental and economic benefits.
