High pressure-temperature phase equilibrium
Webregion of low temperature and high pressure such that the feed stream separates into a CO 2-rich liquid phase and a H 2-rich gas phase. The available phase equilibrium data suggest that pressure of between (5 and 10) MPa andtemperatures in the region of 220 K appears to be most suitable [2]. The key binary system in this case is (CO 2 + H WebApr 12, 2024 · At high pressures, a substance may have additional triple points for two solid phases and the liquid, or for three solid phases. This is illustrated by the pressure–temperature phase diagram of H 2 O in Fig. 8.4, which extends to pressures up …
