Operation conditions of acetylene with concentrated sulfuric acid for cleaning
Thread Content
I would like to know which companies are currently using concentrated sulfuric acid to purify acetylene gas, and what the performance of this method is like in terms of safety and reliability Is the acetylene cracking serious, and could it cause blockages in the packing?

The purification process using concentrated sulfuric acid is quite mature; whether to use it depends mainly on the needs of the individual enterprise. Using concentrated sulfuric acid for cleaning mainly helps reduce water consumption (for the preparation of sodium hypochlorite and waste liquid); if the recycling of calcium carbide cleaning solution is proper, there is no need to use the concentrated sulfuric acid process. The concentrated sulfuric acid cleaning process requires attention to the consumption of concentrated sulfuric acid and the issue of acetylene carbonization, as well as to the impact of carbides on subsequent production.
