Chaan legal alkali production process

Thread Content

1. I would like to ask about the specific manufacturing process for Chian Legal Alkali. I have only seen a general description of the process, but not the detailed steps involved. 2. That design institute can design the Chai’an soda ash production plant. Thank you

1. The main process in producing Caian soda ash involves first reacting sodium hydroxide with table salt to produce sodium chloride and a sodium hydroxide solution; Then, sodium hydroxide solution is added to the potassium chloride raw material to carry out a reaction, producing potassium carbonate and sodium chloride ; Finally, soda ash product is obtained through heating to evaporate water and a crystallization process. The specific manufacturing process may vary depending on the manufacturer. 2. There are many design institutes involved in the design of Caian process for alkali production; companies such as MCC, China Metallurgical Group, and Huaneng all have relevant experience in this area. It is necessary to select an appropriate design firm for consultation and collaboration based on your specific requirements and project circumstances. .

1. The production process of Chai’an legal alkali mainly includes the following steps: (1) Atmospheric roasting: The raw materials, limestone or soda ash, are heated and roasted to decompose them into calcium oxide or sodium oxide. (2) Leaching: The calcined limestone or soda lime is leached with water to obtain a calcium or sodium aqueous solution. (3) Adjusting pH value: By adjusting the pH of the solution, it is made suitable for the next reaction. (4) Carbonation: Reacting an aqueous solution of calcium or sodium with carbon dioxide to produce calcium carbonate or sodium carbonate. (5) Oxidation: Calcium carbonate or sodium carbonate is oxidized to obtain calcium oxide or sodium oxide. (6) Separation: Separate calcium oxide or sodium oxide from the by-products. (7) Refining: The separated calcium oxide or sodium oxide is subjected to refining treatment. 2. Regarding the design institutes responsible for the design of Caian legal alkali production processes, one can contact design institutes in fields such as chemical engineering, metallurgy, coal chemistry, light industry, and machinery manufacturing, such as the China Building Materials Science Research Institute, Beijing Mining and Metallurgy Technology Group, and China Light Industry Metallurgical Design and Research Institute. These design institutes possess extensive design experience and specialized technical skills, enabling them to provide comprehensive design solutions.

Chaan legal soda is produced by reacting a saturated sodium chloride solution with ammonium bicarbonate to form sodium bicarbonate precipitate; the sodium bicarbonate is then separated, dried, and calcined to yield soda ash

This post was last edited by qugd on 2023-6-9 08:59. Do you really understand the principle of the Chaoan legal alkali production process? Judging from the content of your post, you are a complete amateur. When sodium hydroxide reacts with table salt and potassium chloride is added as well, it’s clear from these mistakes that you have no understanding of the processes used in inorganic chemistry for producing alkalis, and your foundation in inorganic chemistry is likely very weak. Go home and take a good look at the Solvay process and the Hou process for soda production, then come back to discuss this process. If it’s a copied post, remember to get it right next time; otherwise you’ll be laughed at.

That guy just doesn’t know where he got those notes from; he’s a complete idiot when it comes to inorganic chemistry. Even if you correct him, he still won’t understand.

Haha, this could be ChatGPT’s answer. It reminds me of a joke: back when there were no mobile navigation apps, people often needed to ask for directions, and some Beijingers would just point in a random direction.

After reading it, it seems to be another case of a layperson giving advice to experts, misleading many people. Without going into further details, the fact that sodium hydroxide and potassium chloride can produce potassium hydrochloride and sodium chloride is something that only students in grades below eighth grade might believe.

The Schanz process seems to be a German technique that involves reacting ammonium bicarbonate with sodium chloride to produce sodium bicarbonate and ammonium chloride, which are then calcined to obtain soda ash. Back then, Hou Lao became angry because the terms offered by the German company were too harsh; he decided to rely on his own efforts and developed the combined alkali process. Some domestic companies are currently using this process, and I have also seen similar processes in which sodium chloride is replaced with sodium sulfate to produce soda ash.
