Non-Condensable Gasses (NCG)

Unlike steam, these gases do not condense into a liquid at the cooling temperatures and pressures found inside a power plant or during drilling or Well Control operations. Therefore, they remain in a gaseous state after the steam has turned back into water. This property is what defines them as “non-condensable.” (E.g., Carbon dioxide (CO2), Hydrogen sulfide (H2S), Methane (CH4), Ammonia (NH3), Nitrogen (N2), Hydrogen (H2))
