Tail gas treatment method for chloroacetyl chloride plant
Thread Content
The exhaust gas from the chloroacetyl chloride plant contains hydrogen chloride and sulfur dioxide, in a ratio of roughly 2:1. How is sulfur dioxide treated, or is it used to produce any products? And then, what should be done with the sodium sulfite in the hydrochloric acid that is produced?
;P Are you from Hongfeng or Kangrui? Lol, we chose Nanjing Industrial for this project – it uses compression and liquefaction followed by distillation to separate hydrochloric acid and sulfur dioxide. . . Payment will be made in a few days and the equipment will arrive; I’ll drive it and see how it performs in the second half of the year
Correction: How to handle sulfur dioxide in hydrochloric acid.
Where are you from: lol. If you compress it first, there’s acid inside – will your compressor be able to handle that? Also, if sulfur dioxide is impure, the liquefaction will not be complete!
Could Haiyou provide the contact information?
I haven’t received the design drawings yet; there is no water in our vapor phase. . . Go straight to compression, then liquefaction followed by distillation. The technical department has gotten in touch with a teacher surnamed Chen from Nanjing Industrial; I’ll ask him later
Hello, Haiyou! By my treatment with sulfur dioxide and hydrogen chloride, I mean the treatment carried out before the formation of sulfonyl chloride. I see that you also mentioned compression distillation in other posts, but that post referred to sulfur dioxide and hydrogen chloride after the formation of sulfonyl chloride. Is your operating condition also related to treating the exhaust gases from chloroacetyl chloride plants?
@*ngjiecheng012: If you have time, please leave a message or your contact information too! Thank you!
Sulfoxide chloride seems to be produced by absorbing hydrogen chloride to form hydrochloric acid, and then by drying sulfur dioxide. Hydrochloride is sold at high prices, or it can be used to produce chloromethane
Thank you for your guidance! It’s mainly that I don’t quite understand the process!
