Abstract
A method for the extraction of xenon gas bound to a filter material using supercritical CO2 to form a mixture in which both CO2 and xenon are in a supercritical state.
Claims22
1-13. (canceled)
A method of reclaiming xenon anaesthetic agent, comprising:
- i) passing gas including xenon anaesthetic agent from a medical environment through a filter so that xenon anaesthetic agent becomes bound to the filter;
- ii) subjecting the filter to a supercritical fluid to carry the xenon anaesthetic agent from the filter;
- and
- iii) separating the xenon anaesthetic agent from the supercritical fluid.
An apparatus to recover xenon anaesthetic agent from a medical environment, comprising a container including a filter through which medical environment gas can be passed so that xenon anaesthetic agent can become reversibly bound thereto.
The apparatus as claimed in claim 9, the apparatus further comprising a pressure-tolerant vessel that is pressure-tolerant above the critical pressure of carbon dioxide.
