As the title suggests, what is the amount of acid produced as a by-product? And after it has been used, what is the total amount of acid present in the entire system?

Where are you from, friend? Anhydrous hydrogen chloride, a by-product of MDI, can be used in the production of VCM or processed separately to produce other products.

Thank you. I’m from Shanghai, and the data I have shows that 0.5 to 0.6 tons of salt and acidic gases are produced per ton of MDI. I’m not sure if this figure is accurate
