What are the requirements for selecting materials for high purity nitrogen gas distribution pipelines in small air separation unit?

What are the requirements for selecting materials for high purity nitrogen gas distribution pipelines in small air separation unit? High purity nitrogen gas has to be transported through pipelines to the point of use of the small air separation unit. In order to meet the quality requirements of the gas for the process, the selection of materials for the piping system and the quality of construction need to be paid more attention to during the construction process, provided that the gas ...

Why is there both liquid and gaseous nitrogen at the top of the air separation tower?

Because gas and liquid nitrogen are in a coexisting saturated state and have the same saturation temperature. However, saturated liquid and saturated vapour at the same temperature belong to different states. A saturated vapour gives off heat to condense into a saturated liquid, and when the temperature remains constant, the saturated liquid absorbs heat to evaporate into a saturated vapour. For the sa...
