Most non-compliant vapor recovery inspections are due to these issues.

Flare gas recovery systems require regular inspections; any systems failing to meet the required standards must be addressed promptly to ensure the smooth operation of the recovery process. Common issues leading to non-compliance in flare gas recovery inspections often include seal integrity, liquid resistance, gas-to-liquid ratio, and issues with the inspection interfaces. Let's delve into these specifics together.

1. Airtightness: Is the entire vapor recovery system leaking? This system includes: gas return copper tubes of fuel dispensers, underground vapor recovery pipelines, condensate tanks, oil tanks, and ground vent pipes.

A leak in any area disqualifies the product.

Please note: During the inspection, all copper tee valves within the fuel dispensers must be kept open.

2. Hydrodynamic Resistance: It is the measurement of whether oil and gas flow smoothly through pipelines.

Please note: During the inspection, the oil vapor recovery port, located next to the oil unloading port, must be opened once.

3. Fuel-to-air ratio: Can the fuel ejected from the nozzle effectively suck back in air?

4. Testing Interface: Ensuring the testing interface is qualified, in a nutshell, is about verifying whether it can properly connect to the intake pipe of the testing instrument.

5. Other appearances: For instance, does the oil gun exhaust cover exist and is it damaged?

When an oil vapor recovery device fails the inspection, we should first consider if any of the following issues are to blame, and conduct checks to identify any problems. This is all the knowledge you need regarding oil vapor recovery devices.
