A team of researchers has developed an innovative method to purify natural gas, removing hydrogen sulfide (H₂S) and carbon dioxide (CO₂) using iron oxide nanoparticles and a magnetic field. This technique addresses a critical challenge in the gas industry, as both H₂S and CO₂ are corrosive and polluting impurities that must be removed before natural gas can be safely and efficiently transported and utilized. The advance promises to improve the sustainability and cost-effectiveness of natural gas production.
