Separation of insoluble material from coal liquefaction ...

9 · Insoluble materials are separated from a coal liquefaction product having a quinoline insoluble content of greater than 15 wt. % by diluting the product with a diluent which is a solvent for the components which are quinoline soluble and benzene insoluble, with the diluent being added in an amount to provide a mixture having a quinoline insoluble content of no greater than 13 wt. %.

Separators

If buffer plates are added to a settling tank, the sinking of any particles stops sooner and there is a greater surface area on to which they will fall, helping speed up the separation process. In a centrifugal separator, the same basic principle can be applied, and a corresponding increase in effectiveness achieved, by a stack of special discs.
