초록 ▼

Ambient air, during an on-stream period, is passed serially through a pretreatment adsorbent bed removing moisture and carbon dioxide therefrom and the thus dried and purified air then passed through a main adsorbent bed selective for retention of nitrogen, the oxygen-rich effluent being collected in an expandable receiving vessel. Nitrogen of high purity, is desorbed by suction from the main bed in a direction chamber to that of the initial air charge and passes from the main bed into and through the pretreatment bed to a collection vessel. Preceding the vacuum desorption step both the pretreatment bed and the main bed are rinsed with the high purity nitrogen product gas from a previous stage in the operation. Following evacuation the beds are repressured with a portion of the oxygen-rich gas drawn from the expandable receiving vessel. At least two parallel trains of adsorbent beds are employed in alternating timed sequence for continuity of operation. By operation in the described manner there are recovered for any desired use, nitrogen of high purity and an oxygen-enriched gas product.

대표청구항 ▼

The method for production of high purity nitrogen and an oxygen-enriched product from air containing water vapor and carbon dioxide, which comprises: 1. during an On-stream period carried out at substantially atmospheric pressure a. introducing ambient air into a first bed of adsorbent effective in adsorption of said water vapor and carbon dioxide; b. discharging unadsorbed gaseous effluent from said first adsorbent bed into a second adsorbent bed in series therewith and containing an adsorbent selective in retention of nitrogen as opposed to oxygen; c. continuously during said on-stream period withdrawing from said second bed a primary gaseous effluent stream as an oxygen-rich product having a higher oxygen concentration than the air stream charged to said bed; d. collecting said primary gaseous effluent in an expandable receiver; 2. discontinuing introduction of charge to said first bed of adsorbent and initiating removal of contained gases from said first and second beds by e. first rinsing said beds with high purity nitrogen gas introduced into said first bed and flowed through said bed into and through said second bed at a rate and for a time period sufficient to effect removal of void air from both beds and short of breakthrough of adsorbed water from said first bed; while collecting the rinse gas effluent from said second bed in a receiver separate from that in which said primary effluent was collected; f. discontinuing introduction of said rinse gas to said first bed and the flow thereof to said second bed; g. reducing the pressure at the air inlet end of said first bed while retaining gas flow communication between said first and second beds and causing substantially all of the nitrogen retained by said adsorbent during step (b) to flow through said first bed, thereby inducing desorption of water vapor and carbon dioxide from said first bed and desorption of nitrogen from said second bed; h. collecting the desorbed gases rich in nitrogen in an expandable receiver, a portion of which collected gases from said receiver is employed as rinse gas in step (e); i. thereafter discontinuing gas flow communication between said second and first bed, while continuing withdrawal of gas only from said first bed to a further reduced pressure level; j. during said continued withdrawal of gas from said first bed introducing into said second bed a portion of the oxygen-rich primary effluent from step (d) thereby restoring said second bed to substantially its initial on-stream pressure; k. thereafter discontinuing withdrawal of gas from said first bed and restoring gas flow communication between said second and first bed to permit flow of contained pressuring gas from said second to said first bed to bring said first bed to substantially its on-stream pressure; 1. when said first bed has substantially reached its on-stream pressure again initiating a new cycle in the recited sequence with an on-stream period commencing with step (a).
