High purity nitrogen air separation FAQ

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...

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...

Factors affecting the performance of main heat exchanger

The main heat exchanger is the key equipment to ensure the performance of the air separation plant. Its functions in the air separation plant of the molecular sieve pre-filtration process are as follows: recover the cooling capacity of the reflux gas, ensure that the heat exchange temperature difference is within the design range; provide sufficient expansion gas in front of the expander to make up for the cooling loss of the air separation plant; provide raw air for the lower tower under the design conditions; and the working medium is in the main heat exchanger The resistance value in meets the process requirements.
