Hydrochloric acid exhaust gas treatment during shipment
Thread Content
The company has a wharf and a tank farm, and the material contains hydrochloric acid. When loading, there is hydrochloric acid gas floating out of the ship. It comes from the vent. As a wharf, what device should be equipped to absorb it? This post was last edited by johncom on 2009-4-10 16:53 ]
It can be absorbed with water or waste lye.
If recycling is not considered, the advice above is more economical and practical.
Just install a wet absorber on the vent!
The vent port is connected to a temporary pipeline and directly connected to a 10~15% caustic soda solution container to effectively reduce the generation of hydrochloric acid mist.
I wonder if you can provide the type or manufacturer of the equipment. This device is urgently needed to meet environmental protection requirements. Not recycled, just processed.
Using a jet vacuum pump absorbs water better, while alkali absorption wastes resources and requires environmental protection treatment after completion.
It seems even more inappropriate to discharge the absorbed dilute hydrochloric acid on site...
Install an absorption device in the vent, a very ordinary acid gas filter will do.
In the past, the ship wharf was relatively empty, and the design department did not pay much attention to the exhaust gas from hydrochloric acid loading and unloading. If the loading and unloading scale was large, it would be necessary to install an absorption device.
