Discuss the carbon dioxide absorption process in tail chlorine again?
Thread Content
Dear seniors, the process exhaust contains large amounts of chlorine, carbon dioxide, and nitrogen. In the process of using liquid alkali to convert these substances into sodium hypochlorite, liquid alkali also reacts with carbon dioxide to form sodium carbonate, which consumes a large amount of liquid alkali; as a result, the concentration of hypochlorite produced is low. Later, someone suggested using sodium bicarbonate for absorption, as it does not react with carbon dioxide. However, the problem is that the effective chlorine level cannot be increased; it only reaches about 1.1%, whereas other chlor-alkali plants manage to achieve levels of around 3.1%. Are there any operational considerations related to this? Regarding this issue, the forum has been asking about it since 2008 to this day, yet there is still no suitable solution. Can’t this problem be solved?
The forum may not be able to solve it because this problem cannot be resolved through theoretical calculations; experimental research is required. What can be done without funding? What should I reply if I have the answer but haven’t received the money?
