May the exhaust gas from concentrated sulfuric acid storage tanks be released directly into the atmosphere? How does your factory do it?
No, it does not meet the environmental assessment requirements; the caustic washing tower for our concentrated hydrochloric acid tanks was installed by a professional manufacturer
What are the main gas components in the exhaust gases from those concentrated sulfuric acid storage tanks? Can it be brought up to standard by alkaline cleaning?
Most likely, there is SO2; it’s best to take a sample or obtain relevant data, and then take appropriate actions based on the concentration and flow rate
Can acidic gases be released directly into the atmosphere? Ask yourself! It must be sent to the alkali scrubber for treatment.
Concentrated sulfuric acid has very low volatility and is odorless; in production, it is not absorbed using alkaline solutions – it can simply be discharged to a safe location
We have a vent valve installed on top of our concentrated sulfuric acid storage tanks; this vent valve is used to release air into the atmosphere. Sulfuric acid is a non-volatile acid that contains trace amounts of sulfur dioxide dissolved in it. However, within the limits specified by national standards, there is no need to empty such storage tanks, as the sulfur dioxide dissolved in the sulfuric acid only begins to precipitate at high temperatures. Hydrochloric acid and nitric acid are different cases, though. lol
Friend, I’m from Zibo, and environmental regulations here don’t allow it
