【Haichuan Chemical Technology Documentation】Analysis of the Recycling Technology for Producing Hydrochloric Acid (HCl) in MDI Production Analysis of the Recycling Technology for Producing Hydrochloric Acid (HCl) in MDI Production In MDI production, the recycling technology for hydrochloric acid (HCl) is regarded as the \"kidneys\" of the facility. If the phosgene gasification reaction is the heart of MDI, then the treatment of the by-product hydrochloric acid is the key to determining whether the plant can operate continuously. The production of 1 ton of MDI generates approximately 1.2 to 1.5 tons of by-product hydrochloric acid; if this acid cannot be recycled efficiently, the large amount of it can cause even the most advanced plants to cease operations. Today, we will take a close look at this core technology that turns the ordinary into the extraordinary.
