This post was last edited by sunjl1981 on 2013-1-6 at 22:34. I want to use sodium carbonate as the alkaline source for desulfurization; I’m not sure how to submit a material request, what are the required specifications, and what is the approximate market price currently? Please ask my friends for help, thank you! # hcbbs
Quality Standards for Industrial Sodium Carbonate in the People’s Republic of China, GB2101-2004 – Parameter values for Category I, Category II: Premium grade, Premium grade, First-class grade, Conforming grade. Total alkali content (as a mass fraction of Na2CO3 on a dry basis)/% ≥ Total alkali content (as a mass fraction of Na2CO3 on a wet basis)a/% ≥ 99.4, 98.1, 99.2, 97.9, 98.8, 97.5, 98.0, 96.7. Sodium chloride (as a mass fraction of NaCl on a dry basis)/% ≤ 0.3, 0.7, 0.9, 1.2. Mass fraction of iron (Fe) (on a dry basis)/% ≤ 0.003, 0.003, 0.006, 0.010. Sulfates (as a mass fraction of SO4 on a dry basis)b/% ≤ 0.03, 0.03. Mass fraction of water-insoluble substances/% ≤ 0.02, 0.03, 0.10, 0.15. Bulk density/(g/mL) ≥ 0.85, 0.90, 0.90, 0.90. Particle size c, residue on sieve/%: For particles of 180 μm, ≥ 75.0; for particles of 1.18 mm, ≤ 2.0. a represents the content at the time of packaging; the value obtained by multiplying the total alkali content in the product by the mass of the delivered product and dividing by the mass of the product specified in the delivery list must not be lower than this value. b is the control index for ammonia-alkali products. c refers to the control criteria for heavy soda ash: Category I: high-quality heavy sodium carbonate with low salt content; Category II: ordinary sodium carbonate. The current price is approximately 1,100 yuan per ton
