Introduction

Carbon dioxide storage underground is an important technology for anthropogenic climate change mitigation as well as enhanced energy resources extraction [1].

Economic usage and storage of CO2 mandates a network of pipelines to transport the fluid from large point sources to their respective injection sites as supercritical fluids.

Impurities (N2, O2, H2O, etc.) in the CO2 stream can increase the temperature and pressure at which water condenses.

• Operation at supercritical conditions for pure CO2 can lead to corrosion and ultimately leakage as a result of liquid-phase acidification[2].

Pressure variation experiment for chip at T = 43.5 ± 0.5℃ with water content 𝑦𝐻2𝑂 = 0.005171 (expect dew at 𝑃 ≅ 1600𝑝𝑠𝑖 from literature) .

1650psi

1550psi

1585psi

Dew-point pressure for 𝑦𝐻2𝑂 = 0.005171,

T = 43.5℃ is at 𝑃𝐷𝑃 = 1583𝑝𝑠𝑖.

Dew-point can also be determined by varying temperature for fixed pressures.

• Dew formation is much more sensitive to pressure than temperature.

• Heat transfer in microchannels is dominated by forced convective boiling corresponding to annular flow [4], which is a strong function of mass velocity (dictated by pressure), only weakly related to heat flux (temperature).

For the sake of precision and speed, we use the pressure variation with fixed temperature method.

Future work include determination of (P,T) pairs for a fixed water content as well as reduced water contents in CO2-H2O systems as well as systems with industrial impurities.

Concept

Impurity species and levels change the thermodynamic conditions at which water condenses.

• We can optically visualize this phase change at the microscale using a microfluidic platform with ordinary microscopy under a pressure and temperature setup

Water mole fractions at saturation for the 30℃, 40℃, 50℃, and 75 ℃ isotherms [3].

Compositions to be tested:

• 82.5-97.4% CO2, with minor components in N2, O2, Ar, CH4

Ranges of interest are:

• 35℃ ≤ 𝑇 ≤ 60℃

• 8.6, 𝑀𝑃𝑎 ≤ 𝑃 ≤ 17.2 𝑀𝑃𝑎
