Hydrogen sulfide—a poisonous substance—is typically emitted during the extraction of oil and gas, and it also accompanies the processes of the coal chemical industry.
A team of researchers from the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences studied possibilities for decomposing the hazardous gas under the influence of light and electricity for over 20 years.
Ultimately, the specialists managed to devise a technique that will help eliminate 100,000 cubic meters of hydrogen sulfide yearly, yielding high-purity hydrogen and sulfur in the process.
The demonstration project has already passed review in Beijing.
