工藝流程簡(jiǎn)介：
原料空氣經(jīng)壓縮機增壓后，壓縮空氣進(jìn)入空氣緩沖罐以減緩氣流的脈動(dòng)，然后進(jìn)入除油過(guò)濾器，把水珠、油霧除去。干凈壓縮空氣進(jìn)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(shí)獲得氮氣，吸附塔飽和后，自動(dòng)切換，該吸附器減壓至大氣壓力再生。本設備設置2個(gè)吸附器交替使用，以連續獲得產(chǎn)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.
