Abstract
An apparatus and process for oxygen production can be configured to utilize flash vapor losses, recovery of regeneration heat and/or utilize a compressor to provide better heat integration and/or less wasteful processing for the recovery of oxygen that can be obtained from electrolysis (e.g., operation of one or more electrolyzers). Some embodiments may utilize all three of these features while other embodiments may use only one of these features or a combination of two of these features.
Claims21
An apparatus for oxygen production, the apparatus comprising:
- a reactor positioned to receive a feed comprising oxygen and water for dehydrogenation of the feed and output dehydrogenated feed;
- a cooler positioned to receive the dehydrogenated feed output from the reactor to cool the dehydrogenated feed to a temperature within a pre-selected temperature range;
- and
- an adsorption system positioned to receive at least a portion of the cooled dehydrogenated feed after it is output from the cooler to remove moisture and/or impurities from the dehydrogenated feed to output an oxygen gas stream that is comprised of at least 90 volume percent (vol %) oxygen.
A process for production of oxygen from a feed output from at least one electrolyzer, the process comprising:
- feeding a feed output from at least one electrolyzer to a reactor to form a dehydrogenated feed, the feed comprising oxygen and water;
- outputting the dehydrogenated feed from the reactor;
- passing at least a portion of the dehydrogenated feed output from the reactor to a cooler to cool the dehydrogenated feed to a temperature within a pre-selected temperature range and for forming a cooled dehydrogenated feed;
- feeding the cooled dehydrogenated feed towards an adsorption system to remove moisture and/or impurities from the cooled dehydrogenated feed to output an oxygen gas stream that is comprised of at least 90 volume percent (vol %) oxygen.
