GHG (Greenhouse Gas)


GHG (Greenhouse Gas)

This refers to gaseous substances in the air that cause global warming.

As the temperature of GHG in the air rises, the temperature of the surface of the earth increases.

6 Critical Greenhouse Gases

  • 01 Carbon Dioxide[CO2]

    CO2 is produced by deforestation, energy use, and the combustion of fossil fuels, such as coal and petroleum. The global warming potential (GWP) is 1, and it accounts for 88.6% of the total emission.

  • 02 Methane[CH4]

    Methane is usually produced by rearing livestock and from wetlands, rice paddies, food waste, etc. The GWP is 21, and it accounts for 4.8% of the total emission.

  • 03 Nitrous Oxide[N2O]

    Nitrous oxide is usually produced by the use of coal and chemical fertilizers, such as nitrogen fertilizer, and waste incineration. The GWP is 310, and it accounts for 2.8% of the total emission.

  • 04 Hydrofluorocarbons[HFCs]

    Hydrofluorocarbons are usually produced by air conditioner refrigerant and spray propellants. The GWP is is 140-11,700.

  • 05 Perfluorocarbon[PFCs]

    This gas is emitted from semiconductor cleaning agents, etc. The GWP is 6,500-9,200.

  • 06 Sulphur Hexafluoride[SF6]

    This is mainly produced by electric products, electric transformers, and insulators used in display manufacturing. The GWP is 23,900.


  • 01 PFCs Treatment Technology

    Our catalytic PFCs decomposition system was developed with the world’s first large capacity. Non-metallic catalytic forming technology, which is suitable for large systems, is applied, and energy consumption is lower than direct heat incineration, and 95% heat recovery is possible.

  • 02 Hybrid PFCs Decomposition System

    Our catalytic PFCs decomposition system and plasma method are applied to this hybrid product. With the size of the product miniaturized, space utilization is increased. The product is more economical and efficient since only the advantages of the catalytic method and the plasma method have been combined is.

  • 03 De-N2O & NOx Treatment Technology

    The De-N2O & NOx System is equipment that breaks down N2 + H2O using catalysts such as N2O and NOx. With just one kind of catalyst, N2O and NOx can be removed at the same time. Located in the front or back end of a turbine, the system is operated at 400~500℃ and NH3 is used as a reducing agent.
