Oxygen Separated from Air Hospital Air Separation Plant
Air Separation Plant technique is using air as raw materials,
through gas expansion refrigeration precess to liquefaction of
atmospheric air ,and separate Oxygen,Nitrogen and Argon from air,
and obtains oxygen,nitrogen, argon products from air.
Air Separation Plant (ASU) adopts molecular sieve air purification,
booster turbine expander, medium pressure air cycle refrigeration,
double rectification column, full liquid air separation. The
control and interlock of complete set plant will be operation in
DCS or PLC system, the process will follow the most advanced and
common international regulation, and design module on the premise
of stable running. The Air Separation Plant including: air
filtration system, air compressor system, air pre-cooling system,
molecular sieve purification system, double rectification column
system, liquid products storage system(if liquid products),
instrument control system, electric control system etc.
Widely used in manufacturing the hydrogen and nitrogen at
protective atmosphere. Especially for metal heating treatment
,powder metallurgy electronics and others heating.as a ammonia
decomposition furnace, it can make hydrogen and nitrogen as
protective atomosphere in non-ferrous metal, silicon steel, chrome
steel and stainless steel and other metal materials and parts it
can be used in bright annealing, in silicon steel it plays a role
in decarburization ,in iron processing base powder metallurgy etc.
