How to choose the installation environment of molecular sieve pressure swing adsorption (PSA) oxygen (nitrogen) systemReturn
Molecular sieve pressure swing adsorption (PSA) air separation technology is a low-cost, convenient and fast to obtain oxygen (nitrogen) gas technology. In fact, it also has certain requirements for the environment. Only in a suitable environment can molecular sieve pressure swing adsorption (PSA) oxygen (nitrogen) system system performance to the maximum.
Specifically, when installing the PSA oxygen (nitrogen) system, three points are mainly considered, ambient temperature, altitude and humidity.
The ambient conditions of inlet air to the air compressor can affect the net weight of the compressed air that is ultimately delivered to the system. An increase in ambient air temperature reduces the efficiency of air compressors and air dryers. So this inlet air temperature is recommended to stay within the design specification. The design operating temperature can be maintained if the compressor/dryer/booster is air cooled.
The higher the altitude, the lower the air pressure, the less oxygen in the air, and the less oxygen or nitrogen used for air separation. In order to separate oxygen (nitrogen) as at normal altitude, the compressor needs to use more power to pump higher volumes of air. In brief, in high-altitude areas, the power of the selected compressor should also be larger.
The effect of humidity is not as pronounced as that of altitude or temperature. But be aware of extreme cases and take appropriate measures, such as increasing the treatment of moisture in the air.
