Abstract
The present invention relates to a cryogenic process and apparatus for production of an oxygen product from air, characterized in that a multiple passage plate-fin heatexchanger having at least two sets of passages is used to effectuate the rectifying and stripping functions, wherein one set of passages comprises a continuous-contact rectification dephlegmator which rectifies the separator vapor and produces the enriched-nitrogen rectifier overhead and the crude liquid oxygen bottoms; wherein a second set of passages comprises a continuous-contact stripping dephlegmator which strips the oxygen-enriched liquid to produce the nitrogen-enriched stripper overhead and the oxygen product; wherein reflux of the rectification device and boilup for the stripping device is provided, at least in part, by indirect heat exchange between and along said two sets of passages, thereby producing a thermal link between the rectificationdephlegmator and the stripping dephlegmator.
