Quicklime desulfurization analysis
Thread Content
Our company currently uses quicklime to absorb sulfur dioxide emissions, but after the reaction, the sodium hydroxide content in the filter cake starts at around 4%, and it is now roughly around 2%. The calcium sulfite and calcium oxide contents in the filter residue are both around 30%. What’s going on? Need help.
Are there full analysis data including the filter residue? Including water content. I think it’s due to the conversion of the analysis data for your filter residue. Also, since you use quicklime as the main component for desulfurization, what is sodium hydroxide then? Has any sodium-containing component been added to the lime slurry? Just by saying that, without any data for reference, it’s not that easy to judge.
