As you know, natural gas is a colorless and odorless substance that can be extremely hazardous in the event of a leak. Therefore, specific chemical compounds known as odorants are added to the gas to make it detectable by smell. Various institutions have set minimum odorization levels, but in general, natural gas should be odorized sufficiently so that a person with average olfactory sensitivity can easily detect it when gas concentration reaches one-fifth of the lower explosive limit.

For the first time in the history of the Islamic Republic of Iran, despite over a century of oil and gas production, the dedicated experts and engineers of the knowledge-based company Arya Exir Avijeh have successfully developed the strategic know-how for producing gas odorant substances. After nearly three years of extensive laboratory work, time investment, and high costs, they received final approval from the Ministry of Petroleum. Today, Iran joins the ranks of the four countries worldwide that produce this product, fully meeting domestic needs and paving the way for exports. This achievement prevents the outflow of large amounts of foreign currency annually and ensures national self-sufficiency by eliminating dependence on imports.

This product complies with both national and international oil and gas standards. When added to natural gas, it acts as a warning system to help prevent explosions and fires in residential and industrial areas.

According to the Ministry of Petroleum regulations, if a product is domestically manufactured—even if its price is up to 15% higher than the foreign alternative—it must be prioritized for purchase to support local production. However, this knowledge-based product is offered at a significantly lower price than global rates, while also having the capacity for large-scale exports and foreign currency earnings for the country.
