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.
