Gas recovery in the production of a chilling medium such as carbon dioxide snow |
摘要 |
A method of recovering gas being used to make solid carbon dioxide includes a two step flash down. The first step being at or above the triple point provides a portion of dry gaseous phase which may be more economically recovered than presently known systems. The second step produces the desired solid carbon dioxide and a comparatively small quantity of waste gas. <IMAGE> |
