medium sized air separation plant
  Total power:                     ***8KW
  Total Cooling water:                **0 m
   Starting time:                     ≤*8h
    Heating time:                      ≤*2h
     Running period(The period between two big heating):≥2 years

   a ,The first working condition:        
        Liquid oxygen output :**5L/h(convert into standard gas condition is **0Nm3/h)
        Liquid oxygen purity :*9.6%
        Liquid oxygen pressure :0.5MPa
   b,The second working condition:
        Liquid nitrogen output :**0L/h(convert into standard gas condition is **0Nm3/h)
        Liquid nitrogen purity:*9.**9%
        Liquid nitrogen pressure :0.4MP
  c,The third working condition:
        The liquid oxygen and liquid nitrogen may be produced in the same time according to proportionment.
for example:If liquid oxygen output is **0L/h,then liquid nitrogen output is **0L/h.

       The three working condition may switch produce .  

EQUIPMENT DESCRIPTION:
