Hydrogen chloride recovery process
Treatment of waste liquid containing organic chloride compound
This process is that HCl which is formed by incinerating organic chloride compounds is recovered as HCl solution / gas.
- Complete decomposition of organic compounds
- Efficient heat recovery from high temperature with boiler
- Recovered HCl concentration can be higher than azeotropic composition by adding stripper.
- Waste gas/liquid of organic chloride compounds and organic silicate compounds.
- Pickling waste acid.
