SYSTEMS AND METHODS FOR RECOVERING HELIUM FROM FEED STREAMS CONTAINING CARBON DIOXIDE |
摘要 |
<p>Systems and methods are provided for recovering helium from a feed comprising helium, carbon dioxide, and at least one intermediate component having a volatility between those of helium and carbon dioxide. In particular, processes of the present invention comprise separating the carbon dioxide and the components of intermediate volatility from the helium at a temperature greater than -82.7 °C to form a helium- rich product stream, wherein the concentration of at least one of the intermediate components in the helium-rich product stream is lower than its concentration in the feed stream, and wherein at least part of the separation is effected by contacting a vapor with a liquid.</p> |
