Carbon-alkali method for producing soda ash
Thread Content
What are the important control parameters of the soda ash production process using the carbon-alkali method?
crystallization: Salting out sodium ions, cooling out temperature, salting out γ value, finished product AII fixed ammonium, solid-liquid ratio, cold AIα value, finished product AIIβ value, cold AI feeding temperature, external cooler circulating liquid temperature difference, etc. Carbonization: Temperature in the middle of the carbonization tower, take-out temperature, fixed ammonium in the take-out liquid, chlorine difference in the filtered liquid, heavy alkali salt content, heavy alkali burning rate, carbonization tower liquid level, etc.: High-pressure steam pressure, alkali discharge temperature, furnace head negative pressure, furnace gas temperature, alkalinity of alkali recovery liquid, calcining furnace host current, ammonia content of light ammonia distillation waste liquid, etc. Haha, that’s what’s important.
