Flue gas desulfurization
Thread Content
Dear sea friends, our company wants to recover sulfur dioxide from flue gas to produce sulfuric acid. However, due to the low concentration, adsorption for concentration enhancement is required. Does anyone know what the cost of this adsorption process is (expressed per ton of concentrated sulfuric acid)? What is the cost of producing concentrated acid from concentrated sulfur dioxide? First, thank you all. Can production costs be reduced compared to market-grade concentrated acid? When will the investment be recouped?
To produce acid from sulfur dioxide in flue gas, how much flue gas is required?
What adsorbent do you use to concentrate sulfur dioxide?
First is the concentration of sulfur dioxide in your flue gas, followed by the type of adsorbent used; only then can the costs be calculated, and this also depends on the volume of flue gas generated by your company as well as the scale of acid production
Sulfur dioxide regeneration technology using active adsorbents; sulfur dioxide concentration: 15,000 mg/Nm3; flue gas volume: 56,000 Nm3/H; 98% concentrated acid is produced, with an annual output of approximately 10,000 tons
Is anti-corrosion paint needed? 1041 flue gas anti-corrosion coating, with a temperature resistance of 750°C and a film thickness of 0.3–0.6 mm
Concentration can be achieved using ionic liquid technology, with costs of a few hundred yuan per ton of sulfur dioxide processed
Is this just the cost of the concentration process? Including acid production, how high will the total cost be?
Of course, the value of sulfuric acid cannot offset the operating costs
