Process
Methane CH4 Gas is the principal constituent of natural gas (typically natural gas is 87% methane). It is therefore commonly produced by purifying natural gas.
Pure methane may also be obtained from the cracking of petroleum fractions.

TECHNICAL QUESTIONS
Frequently Asked Questions About Methane (CH₄) Gas
Methane burns efficiently and produces a high heat output with lower carbon dioxide emissions compared to coal and oil. It also generates very little soot or particulates, making it suitable for clean combustion processes.
At standard temperature and pressure (0°C and 1 atm), methane has a density of approximately:
0.656 kg/m³
This means methane is lighter than air, so in the event of a leak, it tends to rise and disperse in well-ventilated areas.
Methane can be supplied in several forms depending on volume and application, including compressed methane gas cylinders for laboratories and small-scale industrial use, cylinder bundles or tube trailers for medium to large consumption sites, and liquefied natural gas (LNG) tanks for large-scale energy and industrial fuel applications.
Compressed methane is typically filled into high-pressure gas cylinders at pressures such as 150 bar, 200 bar, or 250 bar, depending on cylinder specification and national standards.
Methane cylinders are usually manufactured from seamless steel for high strength and durability and are designed and certified according to international standards such as ISO, EN, DOT, or GB.
