The gas consumption of heavy ash is basically one ton of alkali and half a ton of steam, and the gas consumption is generally more than 400 kilograms. The power consumption is not necessarily certain. The power consumption is high when using a fluidized bed, but low when using a calciner. We use a fluidized bed, and the power consumption is about 35kwh. Water consumption is about 0.3 cubic meters/ton of alkali. The processes of each enterprise are different and the consumption indicators are different. Heavy ash furnaces generally use flash gas from light ash furnaces, which may not be included in consumption.
Hello, I saw that you have replied to many posts on the forum. You are an expert on soda ash. I would like to ask you to help me analyze it. Our company's annual soda ash consumption is about 5,000 tons, and sodium chloride is a by-product. Currently, the sales of sodium chloride is a problem, and the annual volume is about 10,000 tons. It is now planned to use the metathesis reaction of sodium chloride and ammonium bicarbonate to produce soda ash to achieve a circular economy. I don't know if this process is possible. Thanks!

From the reaction point of view, sodium chloride and ammonium bicarbonate can produce soda ash and ammonium chloride, but I have never seen or heard of this process in the industry. First of all, this reaction must be carried out in a liquid state. Direct burning is probably not possible. ； Second, sodium chloride is relatively stable. Can it react directly with ammonium bicarbonate? The third equipment investment is too large. 3. You need to consider the sales of soda ash and ammonium chloride.
The company's by-product is solid sodium chloride. Since the quality is not very good (hydrochloric acid turns yellow), sales are problematic. If sodium chloride and ammonium bicarbonate can be used to make alkali, there is no need to worry about the sales of soda ash. Our company can digest it internally. We can still buy 4 or 5 hundred ammonium chloride per ton.
It is indeed possible to build a soda ash plant with the resource advantage of sodium chloride, but why must ammonium bicarbonate be used? This production method has indeed never been seen before.
The heavy ash fluidized bed has high steam consumption, while the heavy ash calciner has low steam consumption.
It is feasible to use sodium chloride and ammonium bicarbonate to produce soda ash. This is how the baking soda synthesis method is currently produced. For example, in Hunan Yuhua, sodium chloride and ammonium bicarbonate (or ammonium bicarbonate) are used for the metathesis reaction to generate sodium bicarbonate and ammonium chloride. After filtering the sodium bicarbonate, the filtrate is evaporated to produce ammonium chloride.
I have never heard of such a production process. The market for ammonium chloride is not good now. I have heard that the ammonia in ammonium chloride can be recovered. Is there such a process?
Hello, I read your post and it turns out that sodium carbonate and ammonium chloride can be produced by reacting sodium chloride and ammonium bicarbonate, which is Hou's method of making alkali. At present, most domestic soda ash manufacturers use this method. Prices are currently roughly flat. If your quantity is not large, you can use a reactor. If the quantity is large, the process of preparing ammonia salt water and then carbonizing it is generally used. Finally, ammonium chloride is crystallized by cold precipitation and salting out, or it can also be evaporated and crystallized.
