一种获得超高纯氧的制备方法一种超高纯氧的制备方法,它具有至少一塔底有再沸器而不具有塔顶冷凝器的净化精馏塔;至少一具有塔底有再沸器和塔顶有冷凝器的吸收塔;原料氧导入净化精馏塔内,在向下流动时与受再沸器加热蒸发的引向上升蒸汽进行传热与传质,从净化精馏塔上部引出贫烃的氧馏分,并经管道输入吸收塔;在吸收塔内,塔底受再沸器加热蒸发的蒸汽上流与受塔顶冷凝器冷却向下流动的回流液进行传热与传质,最终在吸收塔底部产生超高纯氧产品;所述的净化精馏塔再沸器中的冷凝侧通入有换热流体,该换热流体在冷却到饱和温度,
Method for producing ultra-high purity oxygen A method for preparing ultra-high purity oxygen, which has a purification rectification column with at least a reboiler on the bottom and no overhead condenser; at least one purification rectification column having a bottom A condenser and an absorption tower at the top of the boiler; the raw material oxygen is introduced into the purification and rectification tower, conducts heat and mass transfer to the rising steam heated and evaporated by the reboiler when flowing downward, The upper part of the lean hydrocarbon-depleted oxygen fraction, and the pipeline into the absorption tower; in the absorption tower, the bottom of the reboiler heated by steam evaporation of the upper and the top of the condenser cooling down the flow of reflux liquid heat transfer and mass transfer , Finally producing ultra-high purity oxygen products at the bottom of the absorption tower; the condensing side of the purifying and rectification column reboiler is provided with a heat exchange fluid which is cooled to a saturation temperature,
