Methane Phase Diagram

The horizontal axis shows temperature from 15 to 33 celsius the vertical axis shows pressure from 0 to 120000 kilopascals 0 to 1184 atmospheres. Natural gas as compressed natural gas cng or liquefied natural gas lng are increasingly used as fuels for vehicles to reduce transport emissions and improve air quality.

It is marked point 3 and is approximately 80 c and 50 atm.

Methane phase diagram. Hydrate forms above the line. Methane is used as feed stock to chemical industry and is the main constituent of the fuel natural gas. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.

In addition to the thermodynamics research center trc data available from this site much more physical and chemical property data is available from the following trc products. Methane is easily ignited. Pressure temperature diagram p t diagram figure 52 shows a p t diagram for a pure component.

Phase diagram of water interpreting a phase diagram using the phase diagram for methane ch4 what is the temperature and pressure of the critical point. Methane is a tetrahedral molecule with four equivalent ch bondsits electronic structure is described by four bonding molecular orbitals mos resulting from the overlap of the valence orbitals on c and hthe lowest energy mo is the result of the overlap of the 2s orbital on carbon with the in phase combination of the 1s orbitals on the four hydrogen atoms. Methane is the main component of natural gas a primary energy resource widely used in the energy sector for the production of heat andor electricity.

The line connecting the triple point and critical points is the vapor pressure curve. Ce e phys 2016 18 3272 3279 this journal is the owner societies 2016 cite this physchemchemphys 2016 18 3272 phase diagrams for clathrate hydrates of methane ethane. The extension below the triple point is sublimation point.

Methane hydrate phase diagram. Chemical physical and thermal properties of methane. For example at 4 celsius hydrate forms above a pressure of about 50 atm5000 kpa found at about 500m sea depth.

The critical point is where the liquid gaseous and supercritical fluid phases coexist. Molecular monte carlo simulations are used to compute the three phase hydrateliquid watergas equilibrium lines of methane and carbon dioxide hydrates using the transferable potentials for phase equilibria model for carbon dioxide the united atom optimized potential for liquid simulations model for methane and the tip4pice and tip4p2005 models for water.
