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...

Development scale and application of high purity nitrogen air separation unit

Since the successful development of the first set of high-purity nitrogen air separation unit in China in 1978, the R & D breakthrough of domestic nitrogen production equipment has closely followed the pace of foreign countries, and has achieved leapfrog development in recent decades. At the same time, China's nitrogen production market also shows an upward trend year by year, and the demand for nitrogen p...
