Where is the air separation unit used

The analysis of the working principle of centrifugal compressor I. The explanation of common nouns: (1) level: each level of impeller and its matched fixed components (such as diffuser, etc.) constitute a basic unit, call it a level. For example: Hangzhou oxygen 2TYS100 2TYS76 oxygen turbine compressor high and low pressure cylinder has eight impellers, which is called eight levels. (2) segment: the unit separated by intermediate cooler is called segment. In this way, the compressor can be divided into many sections according to the number of coolers. A section can include many levels, or only one level. (3) standard state: 0℃, 1 standard atmospheric pressure. (4) air intake status: generally refers to the temperature and pressure of the gas at the inlet. (5) weight flow: the weight of gas flowing in one second. Volume flow: the volume of gas flowing in one second. Gauge pressure (G): The pressure measured based on the local atmosphere. Absolute pressure (A): The pressure measured o...

Make use of the difference of the volatile capacity of each component in the mixture, through the reflux of liquid and gas, make the gas and liquid two reverse multi-stage contact, under the constraint of the relationship of thermal energy driving and phase equilibrium, it makes volatile components (light components) transfer continuously from the liquid phase to the gas phase, while the volatile components migrate from the gas phase to the liquid phase, which makes the mixture separate continuously. This process is called rectification. In this process, the process of heat transfer and mass transfer is carried out at the same time, which belongs to the control of mass transfer process. Raw materials enter the tower from the appropriate position in the middle of the tower, and divide the tower into two sections. The upper section is the distillation section without feed, and the lower section contains feed plate as the retention section. The condenser provides liquid reflux from the...
