工藝流程簡介:

原料空氣經壓縮機增壓後,壓縮空氣進入空氣緩沖罐以減緩氣流的脈動,然後進入除油過濾器,把水珠、油霧除去。幹淨壓縮空氣進入吸附器,空氣中的O2、H2O、CO2以及碳氫化合物被吸附劑吸附,同時獲得氮氣,吸附塔飽和後,自動切換,該吸附器減壓至大氣壓力再生。本設備設置2個吸附器交替使用,以連續獲得産品氮氣。設置氮氣儲罐以穩定供氣系統氣壓的穩定。

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.
