Energy Tax Prevention Act this bill would have amended several core components of the Clean Air Act (CAA). Title III of the CAA would have been amended to have the term “greenhouse gas” include: water vapor, carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and any other substance subject to, or proposed to be subject to, regulation, action, or consideration under this Act to address climate change. The Act said that the Administrator of the EPA may take no action involving the consideration of greenhouse gases as pollutants or contributing factors to climate change. It also said that “[nothing] shall cause a greenhouse
Industrial gas ambient temperature is low enough; this includes ethylene (R1150), carbon dioxide (R744), ethane (R170), nitrous oxide (R744A), and sulfur hexafluoride; however, these can only be liquefied under pressure if kept below their critical temperatures which are 9 °C for CH ; 31 °C for CO ; 32 °C for CH ; 36 °C for NO ; 45 °C for SF. All of these substances are also provided as a "Gas" (not a vapor) at the 200 bar pressure in a gas cylinder because that pressure is above their critical pressure. Other gases can only be supplied as liquid if also
