Method of selective HCl and HF extraction from SDW pyrolysis gases
Tóm tắt
Results are provided for a study of the possibility of selective absorption of HCl and HF from a gas stream also containing H2S and CO2. In order to implement this hydrolysis gas cleaning method, it is proposed to maintain the absorbing solution pH in the range 4–5 by neutralizing excess HCl, for example, by means of adding Ca(OH)2.
