Abstract:Life-cycle atmospheric emissions were assessed for the use of Synthetic natural gas (SNG) in refitted coal-fired boilers in Beijing-Tianjin-Hebei. Results show, SNG-fired boilers emit less pollution than traditional coal-fired boilers in the life cycle, while also effects a massive pollution transfer. Further analysis involves the comparison between the emissions from coal-fired boilers with a conventional treatment and SNG-fired boilers. This comparison includes three aspects: life-cycle emissions, resource consumption, and techno-economical analysis. Results show that SNG-fired boilers emit more atmospheric pollutants than the conventional treatment in the life cycle, in addition to consuming more energy and water, having a higher refit investment and operating cost. We conclude that the policy of SNG use for haze prevention should be cautiously implemented, and coal-based synthetic natural gas should not be supported overly.
