摘要： A method and apparatus for producing a ultra-high purity oxygen product in which a nitrogen generator is operated to produce nitrogen and an oxygen rich fraction as column bottoms. Part of the oxygen rich fraction can be further processed at column pressure within rectification column to produce a tower overhead lean in hydrocarbons such as methane, acetylene, propane and propylene. After liquefaction in a head condenser of the rectification column, part of the condensate is further processed in a stripping column to produce an ultra-high purity liquid oxygen column bottoms which can be extracted as product.

摘要： A method of producing gaseous oxygen in accordance with a variable demand cycle in which pumped liquid oxygen from a double column air separation unit is vaporized within a mixing column. During low demand phases, excess liquid oxygen is stored within a storage tank and used to augment the liquid oxygen to vaporized during the high demand phase. Reflux to the lower pressure column of the air separation unit is kept constant by storing liquid with column bottoms produced within the mixing column during the high demand phase for use in the low demand phase when less liquid oxygen is vaporized and therefore less column bottoms is produced in the mixing column.
