About the new soda ash process
Thread Content
I am currently engaged in research on a new process for preparing soda ash from table salt. I urgently need guidance from relevant process and equipment personnel. I can cooperate. I don’t know who is engaged in related work. Please contact me. Thank you. The core content is how to economically decompose ammonium chloride into ammonia and HCl. I don’t know who is interested. We can cooperate in development.
It's the so-called new Xu method. In fact, it's really unnecessary. You might as well study the more promising downstream products of ammonium chloride.
I know about the New Asahi Method, it was done by the Japanese, but mine is not. The new process mainly changes the sodium in sodium chloride into soda ash, and the chloride ions into HCL for use.
You still need to produce ammonium chloride in the intermediate process. Since ammonium chloride is produced, it is better to produce ammonium chloride. Nowadays, almost no one wants the by-product hydrochloric acid given away for free. You've been wasting your energy for a long time, it's not very interesting. Ammonium chloride and quicklime react to form ammonia and calcium chloride. As for how to generate hydrogen chloride, does ammonium chloride react with sulfuric acid to form anhydrous sulfate and hydrogen chloride? Haven't studied it
Hello, although lime and ammonium chloride can react and produce calcium chloride products, the demand for calcium chloride products does not match that of soda ash products, which will result in ammonia evaporation costs. The hydrochloric acid I produce does not have to be sold, I can use it locally.
Your process does not require building an ammonia plant to produce soda ash and hydrochloric acid as a by-product?
It decomposes into ammonia and hydrogen chloride, both of which are easily volatile when heated, which will inevitably make your separation difficult and worsen the production environment. Moreover, this seems to be a reversible reaction. I don’t know how you can find the balance point. If your company needs hydrochloric acid, the market will be ruined. Others can’t deliver it. Just contact us. From an economic and environmental perspective, it is not cost-effective. Now the sales of ammonium chloride are still very good. We are full of drivers here rushing to pull it.
The poster can tell you the general production method. Let’s learn from it.* Discuss it.
The biggest problem in the ammonia-alkali industry is environmental protection, that is, the disposal of calcium chloride and other waste liquids after evaporating ammonia. These plants are generally built on the seaside. Some factories claim to produce calcium chloride and solve the above-mentioned pollution problems. However, the actual global demand for calcium chloride is only 750,000 tons, which is less than the amount of a large domestic ammonia-alkali plant. Our method is to find a circulating medium to replace lime, also evaporate ammonia, and decompose the reacted liquid to prepare HCL.
I actually need to learn more from people in the soda ash industry* , if you are interested, I can seek cooperation.
