Ch4 Phase Diagram. C8ee00139a f8 hi res. Solid liquid and gas regions are seen separated by the coexistence lines.
Phase equilibria of acid gas aqueous systems co 2 h 2 s ch 4 water and in situ ph measurements in application to top of line corrosion birol dindoruk. Phase diagram of ch4. It is easily ignited.
All three phases coexist at the triple point and the liquid gas line terminates at the critical point.
Air liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. T 1 484 10 3 p 204 t 2 833 10 3 p 10 where t 1 and t 2 are the transition temperatures of what we shall refer to as the first and second transitions respectively and p is the pressure. The vapors are lighter than air. Such a phase diagram is shown in fig.
