Coal tar has a high water content and does not separate into layers
Thread Content
The gas water generated during the Luchi gasification process is subjected to gravitational sedimentation to separate coal tar; the moisture content of this coal tar is around 30%, and the temperature of the storage tank is 70°C. Even after 5 days of settling, no significant stratification occurs. Do any experts have good solutions?
1. Add a demulsifier, stir, and then let it stand to remove water. Disadvantage: Demulsifiers are expensive ； A specific demulsifier is required. 2. Stir at high temperature (by mechanical means or gas stirring), then let it stand. Disadvantage: It needs to be determined after experimentation ； Specific equipment is required. 3. Direct distillation dehydration. Disadvantage: A dehydration tower is required ； Light oil is also produced along with it ； The quantity is small. 4. Super horizontal spiral centrifuge. Disadvantage: High price ； A installation site is required. ……
Thank you for the advice. The quality of the tar produced during the coal-to-gas conversion process is directly related to the quality of the coal; currently, centrifuges are used for its treatment.
