Methods for transferring supercritical fluids in microelectronic and other industrial processes |
摘要 |
A method of displacing a supercritical fluid from a pressure vessel (e.g., in a microelectronic manufacturing process), comprises the steps of: providing an enclosed pressure vessel containing a first supercritical fluid (said supercritical fluid preferably comprising carbon dioxide); adding a second fluid (typically also a supercritical fluid) to said vessel, with said second fluid being added at a pressure greater than the pressure of the first supercritical fluid, and with said second fluid having a density less than that of the first supercritical fluid; forming an interface between the first supercritical fluid and the second fluid; and displacing at least a portion of the first supercritical fluid from the vessel with the pressure of the second, preferably fluid while maintaining the interface therebetween.
