Abstract:
     The said carbonizing technology mainly includes the absorption of CO2 by dense ammonia water, the concentration, the centrifugal separation and introduction of liquid chlorine into dense ammonia water. Thus, following reactions take place: Fe(CN)6] to the power 4-=Fe to the power 2 6CN to the power -, Cl2 CN to the power - 2OH to the power --CNO to the power - 2Cl to the power H2O, 2CNO to the power - 2Cl2 4OH to the power --2CO2 6Cl to the power - H2O. In this way, the concentration of Fe (CN)6] to the power 4- is reduced for preventing ammonium bicarbonate from bluing in storage, which affects appearance quality.
