China is the largest producer and consumer of HFC-134a(1,1,1,2-tetrafluoroethane)in the world.Coal-based route is mainly adopted to produce HFC-134a,which suffers from large waste and CO2 emissions.Natural gas is a low-carbon and clean energy resource,and no research has been found on the environment and economy of producing HFC-134a from natural gas.In this study,CML 2001 method was used to carry out the life cycle assessment of natural gas(partial oxidation)-based and natural gas(plasma cracking)-based routes(abbreviated as gas(O)-based and gas(P)-based routes,respectively),and their environmental performances were compared with coal-based and oil-based routes.Meanwhile,considering that China is vigorously promoting the transformation of energy structure,and the application of electric heating equipment to replace fossil-based heating equipment in industrial field,which has a great impact on the environmental performance of the production processes,the authors conducted a scenario analysis.The results showed that the gas(O)-based route had the most favourable environmental benefits.However,the gas(P)-based route had the highest potential for reducing environmental burdens,and its environmental benefit was the most favourable in scenario 2050.Additionally,the economic performance of the gas(P)-based route was significantly better than that of gas(O)-based and coal-based routes.
