Questions regarding acid gas scrubber towers
Thread Content
Can 304 stainless steel be used for high-stack chimneys after acidic gases containing hydrogen chloride and hydrogen fluoride have undergone primary alkaline washing and primary water washing?
It’s great to use fiberglass – it’s cheap and lightweight
I planned to combine it with the exhaust gases from the other two sets containing methanol and ethanol; it seems that fiberglass isn’t very resistant to methanol and ethanol
Non-metals have no problem； Plastic ones are also okay
It is recommended to discharge them separately, as hydrogen chloride and hydrogen fluoride cannot be completely cleaned through alkaline and water washing. Hydrogen chloride and hydrogen fluoride react with methanol and ethanol in the exhaust gases.
For exhaust pipes as well, the electrical conductivity must be taken into account; otherwise, the accumulation of static electricity can easily lead to accidents
Your absorption systems should also be two separate sets; you can’t use just one chimney
