Researchers of Islamic Azad University have collaborated in creating a new nano-adsorbent for sweetening sour gas and absorbing air pollutants.
According to Iran Nanotechnology Initiative Council, researchers from Islamic Azad University, West Tehran branch, the Petroleum Industry Research Institute and Kashan University worked together on this project, which mainly focuses on removing hydrogen sulfide - the primary factor in souring gas. Hydrogen sulfide can be found in many sources including natural gas, biogas and industrial gases. Large amounts of it are produced in petrochemical industry. The significance of hydrogen sulfide stems from its high toxicity, and its state as a potent environmental and industrial pollutant. It is extremely corrosive to pipes and tanks in the presence of a catalyst such as water, and therefore its removal is necessary for protecting equipment and improving safety.
Dr. Masoud Khaleqi Abbass Abadi, one of the researchers, explained that considering Iran’s rich oil and gas resources, coming up with better ways of "sweetening" is essential to optimizing the use of these sources. The aim of this project is to synthesize and introduce a new nano adsorbent which is usable for removing emissions such as hydrogen sulfide.
This nano adsorbent can be applied in sweetening gas in the petrochemical industry and also in reducing environmental pollution. Also complete removal of hydrogen sulfide can solve corrosion problems in reservoirs and pipes.
The results of this investigation are published in the Journal of Sulfur Chemistry, Volume 36, No. 6, 2015, pp 660-671.
