Desulfurization catalyst
Thread Content
For desulfurization using the HPF method, with two towers connected in series, the hydrogen sulfide concentration before the towers is generally 4–5 g/m3. How much catalyst should be added per shift (for a three-shift system)? How to determine the amount of catalyst to add? Desulfurization agent parameters: 1. The product appears as a blue-black or blue-purple loose powder. 2. Its density is 0.69~0.84 g/m3. 3. The particle size ensures 100% passing through a 20-mesh sieve. 4. The water-insoluble content is less than 2%. 5. The H2S concentration in semi-water gas is 1~3 g/m3. 6. The sulfur capacity is 2.8~3 g/L. 7. The absorption temperature is 30~40°C. 8. The regeneration temperature is 30~45°C. 9. The ammonia solution concentration is 12~16 wt%. 10. Consumption: 1.5 g/t of NH3
