Iran develops advanced ultrasonic device to measure flare gases for refineries, petrochemicals

Pars Today – Iranian technologists have successfully designed and produced an ultrasonic flare‑gas flowmeter using advanced time‑of‑flight acoustic technology, reducing the oil and gas industry’s dependence on foreign products.

Researchers at an Iranian knowledge‑based company have developed an ultrasonic flare‑gas flowmeter based on sound time‑of‑flight technology. The product was designed and manufactured relying solely on domestic expertise and without reverse engineering.

According to Pars Today, citing IRIB News Agency, one method for measuring flare gas flow is the use of sound time‑of‑flight technology. Advantages of this method include high accuracy, low sensitivity to gas composition, no obstruction or pressure drop in the pipeline, and the ability to provide monitoring and diagnostic data.

Mohammad‑Mehdi Kharidar, the technical manager of the product at the knowledge‑based company, explained that in refineries, petrochemical plants, and even in oil extraction operations, a portion of produced gases cannot be used for various reasons and is removed from the process.

These gases are burned through a flare system at the top of flare stacks and released into the environment. Therefore, measuring these gases is the first step in managing them, since it is important both for maintaining the refinery’s mass balance and controlling energy loss, as well as for environmental monitoring of pollutants released into nature.
