Effect of coal blending ratio on hydrogen cyanide
Thread Content
Do any of the seniors know about the impact of coal blending ratios on hydrogen cyanide in gas? As long as the cyanide level in the ammonia distillation wastewater remains above the allowed limit, dilute alkali used for alkaline supplementation in the ammonia distillation process is the alkali derived from desulfurization. However, neither the concentration of this dilute alkali used for desulfurization nor the amount of alkali supplied for ammonia distillation has changed; it is suspected that the hydrogen cyanide concentration in the gas has increased. What are everyone’s opinions?
Then, can the ammonia content in the spray liquids used in the primary and final coolers also affect the concentration of hydrogen cyanide in the resulting gas?
