Process for producing high-purity hydrochloric acid from by-product hydrochloric acid
Thread Content
Our company produces hydrochloric acid as a by-product of chlorinated paraffins; we are seeking the most suitable process for producing high-purity hydrochloric acid, and we earnestly hope to receive guidance from those with more experience. Thank you!

Thank you so much! About 300 tons per day; after purification, it meets the requirements for synthetic acid with a concentration of 36%.

It is recommended that you learn about the hydrochloric acid resolution–reabsorption process, and then you will understand.
Nanofiltration can be used for filtration. 1. The removal efficiency for divalent cations (ferrous ions, calcium ions, magnesium ions, copper ions, etc.) and trivalent cations is greater than 95% ； 2. The removal rate of organic substances with a molecular weight of 150-300 or higher is greater than 93%. 3. The solution is colorless and transparent after filtration

Desorption is carried out using hydrochloric acid; the resulting hydrogen chloride gas is then dried through freezing and mist removal, before being used to produce high-purity acid!
