Production process of hydrobromic acid
Thread Content
Could any of the seniors tell me about the detailed production process of hydrobromic acid? I’m a newcomer who has just started working. A flowchart of the hydrobromic acid production process needs to be drawn. It took a very long time without any satisfactory results. I hope the senior can be aware of this.
In the methanol cracking production method, hydrogen is first produced through cracking, which is then combined with bromine at high temperatures to generate hydrogen bromide gas, followed by water absorption.
Sulfur dioxide and bromine are reacted in a synthesis tower; the reaction mixture is distilled to isolate a specific fraction, yielding hydrobromic acid, while the liquid remaining at the bottom of the tank is sulfuric acid； I haven’t done it for over a decade; I can no longer remember the specific parameters, please understand.
Two processes for hydrobromic acid: one involves adding bromine to produce hydrogen bromide, which is then absorbed by water to form hydrobromic acid; the other involves adding hydrobromic acid and sulfur in a reaction vessel, followed by the gradual addition of bromine, with the resulting hydrogen bromide being absorbed by water to yield hydrobromic acid
