Current status of kiln process acid
Thread Content
I would like to ask everyone, what is the current situation of phosphoric acid produced by kiln method at home and abroad? What are the difficulties and prospects?
Research and development was done abroad in the 1970s, but it seems that it has never been commercialized. If you are not optimistic about this product, it will have no future in terms of economy, environmental protection, etc.
Is there any company currently doing something like this?
The problem lies in the later purification of kiln-process phosphoric acid and the product cost of the entire process. Research began in Russia in the 1950s and could not be promoted. China has recently organized research in Hubei.
And the problem of nodules in the kiln is the main problem.
