Under normal circumstances, the solubility of supercritical CO2 increases with the increase of pressure, and the pressure and temperature change appropriately, which will cause the solubility to change within the range of 102-103 times.

The supercritical CO2 cleaning technology utilizes this characteristic during cleaning.

When the pressure is increased, the pollutants can be dissolved in the supercritical CO2 to the maximum extent; and because the surface tension is relatively small, the cleaning of the fine-grade micropores which is difficult to be saturated with ordinary liquid solvents is also possible.

After the end of the washing, CO2 can be separated from the dirt by depressurization or cooling.
