As natural gas becomes more abundant in the US, the demand for liquefied natural gas (LNG) imports is disappearing, while the need to find markets for domestic natural gas is increasing. LNG terminal operators are thus switching from LNG imports, which require regasification, to LNG exports, which require liquefaction, resulting in dramatically changed processing. In liquefaction, new flammable refrigerants have been introduced in large quantities for cryogenic cooling. These compounds can form vapor clouds similar in size to LNG, but the new compounds will reach further and be more reactive than LNG vapors.
