• Detailed Description:

  demand for v2o5 az catalyst use
  in sulphuric acid industr .Our
  technical specification of
  catalyst that we need is az below:
  
  Application: Oxidation of
  S02 to S03 for sulfuric acid
  production.
  
  Composition: Vanadium
  pentoxide and alkali metal
  sulfates on
  special silica support
  
  
  approx. 6% V20S
  
  approx. 7% V20S
  
  approx. 8%V20S
  
  Form: Tubular
  extrudates, 10 mm OD5 mmID
  Extruded
  pellets of 4, 6 and 8 mm diameter
  
  Bulk density:
  approx. 500 g/I (rings)
  
  approx. 600 g/I (pellets)
  and we expect these results from
  catalyst:
  1) Capacity (mt/daY): 60
  2) Feedstock: yes
  (e.g. sulfur burner):
  3) Plant design: single-
  absorption plant
  
  4) Type of cooling:
  ?indirect (heat exchangers)
  ?direct (e,g.air. quenchgas)
  ?in direct:
  volume of air/quenchgas efter each
  bed (Nm3/hr):
  after bed 2: 1192 Nm3 I hr
  after bed 3:1130 Nm3 I hr
  temperature of air/quenchgas after
  each bed :40 c
  composition of quench gas:
  02=21% N 2=79%
  
  5) Catalyst loading:

  (m3): 12
  - Inside diameter of catalyst beds
  (m): 2.6
  - Catalyst volume per bed (m3):
  bed
  1: 2.4
  bed
  2: 2.5
  bed
  3: 2.8

  ?Catalyst loading height per bed
  (cm, actual) :
  bed
  1: 43
  bed
  2: 45
  bed
  3: 50
  bed
  4: 70
  Actual pressure drop across the
  catalyst beds (mbar):
  bed1:20
  
  bed2:19
  bed3:18
  
  bed4:17
  6)Operating data :
  ?Feedgas, first bed:
  Flowrate (Nm3/hr):6700 m3/h
