Carbon emission factor for Magnesium Hydroxide
Carbon emission factor for Magnesium Hydroxide
(OP)
Hello Engineers,
I am currently assessing the Green house gas emission of a lime treatment process for an industrial waste water for Silica removal. As you know Magnesium Hydroxide is an important part of the reaction however this waste water doesnt have any and I need to add some. In my calculation for green house gas emission I need to have the CO2 emission factor for magnesium hydroxide. I was wondering if anyone has the value. I have tried Gabi but it is not available there.
Cheers,
Abraham

RE: Carbon emission factor for Magnesium Hydroxide
I don't know what accuracy that you require. You can probably roughly estimate the energy use by the price of the chemical. Magnesium is a little more costly than lime.
In the silica removal process, you will still be using much more lime than magnesium, so if you used the value for lime, you would still not be that far off.

I don't know what kind of accuracy that you need for your report, but a reasonable assumption would be to use thesame emission factor.
