HELP!!! is not descriptive. Chlorides in Na2CO3

Hi

We have a Copeland fluidized bed reactor where we burn lignin to reclaim sodium carbonate. Chlorides (apparently) play a role in increasing the particle size of the Na2CO3 pellets. Does anyone know why?

RE: HELP!!! is not descriptive. Chlorides in Na2CO3

just going by experience with the kraft recovery process, the chlorides, Cl/(Na+K), increase particle stickiness at a given temeprature and reduce the sticky temperature.

Thanks hacksaw

Eutectics is a recently acquired word in my vocabulary. Google gives it as follows: The lowest temperature at which a mix of two materials will melt. Often the temperature is an anomaly, that is, it is much lower than the melting temperatures of only slightly different mixtures. Lead-tin solder is an example. Lead melts at 327C, tin at 231C. The lowest melting combination is 67 lead, 33 tin (180C). Non-eutectic mixtures have a melting or softening range. Such mixtures do not flow well until thoroughly heated past the softening range. This softening phenomenon is what makes glazes hang onto the ware.

Your post has been very helpful. Thanks
