Abstract
Official abstract text for this publication.
A system and method for the concurrent condensation of a nitrogen-rich vapor and vaporization of an oxygen-rich liquid in a distillation column based air separation unit is provided. The disclosed system includes a condenser-reboiler heat exchanger located between a lower pressure column and a higher pressure column and configured to condense a nitrogen-rich vapor from the higher pressure column and partially vaporize an oxygen-rich liquid from the lower pressure column. Within the condenser-reboiler heat exchanger, the nitrogen-rich vapor flows in an upward direction such that any non-condensables present in the nitrogen-rich vapor will accumulate proximate the upper portion or top of the condenser-reboiler modules where they can be easily removed through venting by means of a venting apparatus having a plurality of perforated tubes.
First claim
Opening claim text (preview).
What is claimed is: 1. A condensation and vaporization system for a distillation column air separation unit comprising: one or more condenser-reboiler modules having a housing defining a top, a bottom, one or more lateral sides, an upper portion, and a lower portion, the one or more condenser- reboiler modules disposed within a lower pressure column and configured to receive a condensing medium at a condensing inlet, an oxygen-rich liquid from the lower pressure column at an oxyge…
