Key Chemical Characteristics

Ultra-clean combustion: Complete combustion only generates CO₂ and water vapor, low carbon emission, low sulfur & particulate pollutants compared with coal and fuel oil.
Main component methane has stable saturated alkane structure; only reacts violently under high temperature with strong oxidants (chlorine, liquid oxygen).
Simple asphyxiant: High concentration displaces oxygen in confined space and causes suffocation; no systemic toxicity.
Cryogenic LNG will cause severe frostbite upon direct skin contact due to ultra-low temperature.
Trace hydrogen sulfide impurity is corrosive to pipelines and toxic; commercial grade desulfurized to ultra-low sulfur standard.
Can be reformed under catalyst to produce synthesis gas (CO + H₂) for downstream chemical manufacturing.

ECHEMI Editorial Reference

Natural gas (described by the TSCA definition below) is an approved ingredient in the generation of “Combustion product gas”, as described in §173.350. Limits of carbon dioxide in the final product (the gas) are set at 4.5% by volume and analytical methodology for testing the gas is prescribed. Combustion product gas is used to displace or remove oxygen in the processing, storage, or packaging of beverage products and other food, except for fresh meats.
Raw natural gas, as found in nature, or a gaseous combination of hydrocarbons having carbon numbers predominantly in the range of C1 through C4 separated from raw natural gas by the removal of natural gas condensate, natural gas liquid, and natural gas condensate/natural gas. Natural gas is a colorless, odorless, flammable gas that occurs naturally along with petroleum deposits in marshes or from waste decomposition and is composed mainly of methane. The gas can be liquefied for transport and storage and is primarily used as fuel.
Colorless, flammable gas or liquid; almost odorless.A warning odor is added to household fuel gas as a safety precaution.
A mixture of low molecular weight hydrocarbons obtained in petroleumbearing regions throughout the world. Its composition is 85% methane 10% ethane, the balance being made up of propane, butane, and nitrogen. In the U.S., it occurs chiefly in the southwestern states and Alaska. An as-yet-unexploited source of natural gas under extremely high pressure (so-called geopressurized gas) exists in Texas and Louisiana at depths of 15,000–20,000 ft. The tremendous pressures involved present formidable engineering problems. Natural gas is classed as a simple asphyxiant. It should not be confused with natural gasoline. About 3% of the natural gas consumed in the U.S. is used as feedstocks by the chemical industries
A flammable liquefied gaseous mixture of straight chain hydrocarbons, predominately methane.

Characteristics

Air and Water Reactions:

Highly flammable.

Reactivity Profile:

Liquid oxygen gives an explosive mixture when combined with liquid methane [NFPA 1991]. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980]. Involved in many explosions when combined with especially powerful oxidizers such as bromine pentafluoride, chlorine trifluoride, chlorine, iodine, heptafluoride, dioxygenyl tetrafluoroborate, dioxygen difluorede, trioxygen difluoride and liquid oxygen. Other violent reactions include, chlorine dioxide and nitrogen trifluoride.
