Does anyone know if there are any safety concerns with CO2 in its supercritical sate?

This is in refrence to Geosequestration (a type of CSS). —The preceding unsigned comment was added by 203.29.214.2 (talk • contribs).

I know that the process has many safety requirements since it is always done under very high pressure. Besides that, I don't know of any environmental of health safety concerns since the CO2 used is always (I think) reclaimed. Sjschen 16:07, 22 August 2006 (UTC)


[edit] Surfactants?

I've read that some companies have produced surfactant molecules that dissolve in supercritical CO2 to assist it's properties in dry cleaning. Interestingly, these surfactants form inside-out micelles (tails pointing outwards). Can anyone expand on this, by any chance? --Xanthine 18:35, 1 September 2006 (UTC)
