In fact, the unit power consumption of oxygen production by air separation refers to the production cost per unit oxygen product. There are many factors affecting this index

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

Device impact: This is easy to understand. If your air compressor and expander performance aging low efficiency, production costs are certainly high.

Process management: leakage is found everywhere in operation, compressor backflow, product venting, and poor adjustment of working conditions will also lead to high production cost.

Equipment management: for example, your air compressor filter resistance is large, but maintenance does not replace, the compressor stage heat exchanger is dirty, heat transfer effect is poor, maintenance is not clean, will lead to increased costs.
