Anodic Protection Concentrated Sulphuric Acid Coolers |
|
Concentrated
Sulphuric Acid Coolers is new type and high efficient Anodic
Protection Shell and Tube Stainless Steel Cooler, which
have widespread employed in the process of producing sulphuric
acid from sulphur, flue gas, zinc concentrates, pyrite. It is
the better cooler for replacing traditional spraying high silicon
cast iron pipe cooler. |
|
Its excellent properties has been confirmed through
putting into operation:
- High heat transfer coefficient
- Less water consumption
- Less assembling space
- More ten years service life
Characteristic:
Anode current is imposed on stainless steel
contacting concentrated sulphuric acid for causing anode polarization
and passivation rapidly. Maintaining voltage, the passivation
film can reduce corrosion of stainless steel at concentrated
sulphuric acid.
Specification:
Used for cooling Concentrated Sulphuric
Acid (H2SO4) from 93% to 98%.
- Design pressure: 0.6 MPa
- Design temperature: < 120
°C
- 93% H2SO4
allowance temperature: < 80 °C
corrosion rate: 0.03mm/a
- 98% H2SO4
allowance temperature: < 120 °C
corrosion rate: 0.01mm/a
