Is the separation of tar and moisture effective?
Thread Content
I have no prior experience with tar-like substances. In the simulations I conducted, the relative density was set to be greater than 1. In actual production, when tar is separated from water, does the tar end up on the upper layer? Is the separation effective? In the simulations, the amount of water present was very low, less than 0.7%. Is there a significant difference between this and what happens in actual production? What thermodynamic methods should be used for simulations? Please advise
Coal tar – I checked and its specific gravity is slightly above 1; then why does it remain on top when layered?
There are many types of coal tar; those with a boiling point above 1°C include medium-temperature coal tar, such as the tar produced by fixed-bed gas generators. There is also high-temperature coal tar, such as the tar produced by coke ovens. Primarily, it is the emulsions that surround the water, resulting in uneven stratification.
It’s difficult to separate; extraction is the only option. Even after extraction, separation remains challenging
