Subsequently, both temperature and pressure are elevated to establish ,supercritical, state for ,CO2, (30.8°C, 73 bar) in the system. Isothermal depressurization then follows to transition the ,CO2, from ,supercritical, state back to gaseous phase for ,drying, without surface tension.

The supercritical dryer is at 15 deg C, and so the vapor pressure of CO2 in the supercritical dryer will be about 700 psi CO2 entering the supercritical dryer will now boil until a pressure of 700 psi is reached, since that’s its vapor pressure at 15 deg C–any additional CO2 pushed into the supercritical dryer can now exist as a liquid

The combination of supercritical CO2 drying and the single-anchor supporting method offers reliable high-precision microfabrication of sophisticated, fragile 3-D micro/nano structures. In high-precision two-photon microfabrication of three-dimensional (3-D) polymeric microstructures, supercritical CO2 drying was employed to reduce surface tension, which tends to cause the collapse of micro/nano structures.

successfully employed ,supercritical CO2, fluid technology in the lithography ,drying, process. The ,supercritical, fluid process eliminates capillary stress induced by liquid-gas phase boundaries and associated interfacial tensions. The effectiveness of this process is well demonstrated in Figure 2, which shows 70nm structures with a 5:1

Hydrolysis and poly-condensation steps were followed by ,CO2 supercritical drying,. The complete ,supercritical drying, step was video recorded in order to study the evolution of the size of the gels, concluding that a noticeable shrinkage only takes place during the decompression of ,CO2, at the end of the ,drying, process, being the total shrinkage of 3-4%.

18/2/2021, · ,Supercritical CO 2, extraction process was investigated for the purpose of ,drying, municipal sewage sludge. Remarkably our results showed that after sCO2 processing the higher heating value (HHV) of sludge at wet basis moisture content of 52% was 14 MJ/kg and thus higher than the HHV of brown coal with similar moisture level (12 MJ/kg).
