What key parameters are mainly controlled in tannin desulfurization?
Thread Content
Dear experts in ammonia synthesis, which parameters are the most critical in the semi-desulfurization process of tannin? Thank you!
There are mainly 1 solution component, including alkalinity, NaVO3 content, and tannin concentration； 2 Temperature ； 3 Absorption pressure ； 4 Oxidation Residence Time ； 5 Carbon dioxide concentration.
The most critical parameters in the semi-desulfurization process of tannin: 1. Total alkalinity of the solution； 2. Content of aVO3 in the solution ； 3. Tannin concentration in the solution ； 4. Absorption temperature.
