Energy saving and consumption reduction of air separation plant

Cooling is a common name in refrigeration, refrigeration is to get lower temperature than the surrounding air, compared with the surrounding air, it has the ability to absorb heat, generally, the heat absorption capacity of low-temperature objects relative to the surrounding air temperature is called cold volume. The lower the temperature of the object is (the bigger the temperature difference between the object and the surrounding air is ). The more the quantity is, the greater the ability to absorb heat, that is, the greater the cooling.

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...
