What factors are related to the unit power consumption of oxygen production in air separation equipment?

The unit power consumption of air separation oxygen production you mentioned actually refers to the production cost of unit oxygen products. There are many factors that can affect this indicator:

Environmental impact: Ambient temperature , the circulating water temperature will affect the isothermal compression efficiency of the air compressor, so the cost is low in winter and high in summer.

Equipment impact: This is easy to understand, if the performance of your air compressor and expander is aging , the efficiency is low, and the production cost must be very high

Process management: If there are leaks and leaks everywhere during operation, there is backflow in the compressor, venting of the product, and the working conditions are not adjusted well, these It will also lead to high production costs

Equipment management: For example, the inlet filter of your air compressor has great resistance, but it is not replaced after maintenance, or the interstage heat exchanger of the compressor is dirty. The heat exchange effect is very poor and maintenance is not carried out without cleaning, which will lead to increased costs.

These all belong to the category of efficiency optimization,
