Epichlorohydrin
Thread Content
How to address the high COD during the cyclization of epichlorohydrin produced by the glycerol method? The finished epichlorohydrin coming out of the light-end and heavy-end removal towers is yellow in color; how can this be resolved?
Is sodium neutralized? It can be fed into the ion membrane after treatment with wet oxygen.
The alkalinity at the bottom of the cyclization tower is controlled at 1%. If the COD is high when using monochloro, is it the calcium method? ?
Each process is different; it is necessary to analyze what exactly the yellow substance is. A high COD value in the cyclization tower indicates a decline in the tower’s efficiency, which leads to an increased level of glycerin.
A high COD level in the cyclization tower indicates a decrease in the tower’s efficiency, which results in an increased amount of glycerol.
