工艺流程简介:

原料空气经压缩机增压后,压缩空气进入空气缓冲罐以减缓气流的脉动,然后进入除油过滤器,把水珠、油雾除去&。干净压缩空气进入吸附器,空气中的O2、H2O、CO2以及碳氢化合物被吸附剂吸附,同时获得氮气,吸附塔饱和后,自动切换,该吸附器减压至大气压力再生&。本设备设置2个吸附器交替使用,以连续获得产品氮气&。设置氮气储罐以稳定供气系统气压的稳定&。

PSA Nitrogen Plant
PROCESS DESCRIPTION
The feed air, after being compressed by the compressor, will enter into the buffer tank to reduce the stream fluctuation, then passes through the filter to remove the moisture and oil mist. The dry and clean compressed air goes into the adsorber, oxygen, moisture and carbon dioxide and other hydrocarbons in the air will be adsorbed, nitrogen is obtained at the same time. The system will change over automatically after the adsorbent is saturated. Then this adsorber will be depressurized to the atmospheric pressure for regeneration. There are two adsorbers working alternatively to obtain product nitrogen continuously. A nitrogen storage tank is provided to stabilize the supply pressure.
