Webcarbon dioxide as the solid commonly known as dry ice, which sublimes into a gas. At higher temperatures and pressures, different phases occur. Carbon dioxide has low triple point (5.1 bar, -57° C) and critical point (72.9 bar, 31° C). At the triple point, carbon dioxide is in triple equilibrium in gas, liquid, and solid phases. At pressures WebApr 5, 2024 · Abstract. The Cryogenic Carbon Capture™ (CCC) process separates CO2 from light gases in essentially any continuous process. CCC cools the gases to the frost or desublimation point of CO2 (-100 to -135 °C), separates and pressurizes the solids, and warms all streams to produce a CO2-depleted stream at ambient pressure and a pure …
