Causes of low air compressor efficiency of small air separation unit

Causes of low air compressor efficiency of small air separation unit There are many reasons for the low efficiency of air compressors, the common ones are: increase in suction temperature at any level, cooler leakage, decrease in grid frequency or voltage, blockage or increase in resistance of the compressor intercooler, gas leakage due to poor sealing, blockage or increase in resistance of the air filter, blockage or increase in resistance of the pipeline of the air separation equipmen...

How to prevent water inflow accident of molecular sieve purifier in small air separation units?

The molecular sieve of purification system has strong water absorption, but the water absorption capacity is limited to a certain extent. In order to prevent the molecular sieve from entering water during operation, the following points should be paid attention to: The air cooling tower should be operated according to the regulations, and the gas should be introduced first, and then after the...

Small air separation unit expander outlet diffuser

After the gas flows out of the expander impeller, there is still a certain speed. This part of mechanical energy without work is called residual speed loss. In order to reduce the velocity of the gas flow at the outlet of the expander, there is generally a section of expanding short pipe at the outlet of the expander impeller. This section of short pipe can reduce the velocity of the air flowing out of the expander impeller, reduce the...

What are the characteristics of the small air separation units for iron and steel？

According to the specification and smelting level of converter, the total oxygen consumption of steel can be calculated and converted to the oxygen consumption of each hour. The low and peak oxygen consumption is balanced by ball irrigation or liquid vaporization. The gas pressure of peripheral comprehensive pipe network is higher than the pressure of final gas consumption point. It is sent to the user thro...
