Abstract: <PICT:0369892/III/1> Coal distillation gases are cooled fractionally to separate therefrom a heavier tar and a lighter tar, and the latter is distilled to pitch and blended with the heavier tar to produce a liquid fuel.  The fuel may be used in open hearth or other steel-melting furnaces.  Gases from a coke oven battery are partially cooled in a main 7 and heavy tar which separates is collected in a tank 11.  Tarry oil is condensed in condensers 9 and collected in tank 18, from the gases issuing from the cross-over main 8.  The oil is pumped directly into a still 22 or it may first be preheated in a heat exchanger 25 before being distilled, the heating medium being hot gases from the battery which are directed by valves to a header 21 for this purpose.  The gases pass to the heat exchanger and a condenser 27 and are removed by an exhauster 28.  Heavier oil vapours are separated from lighter vapours in the exchanger, heavy oil collecting in tank 56 and lighter oil in tank 57.  These oils may be extracted for tar acids and the neutral oil blended with the tar and pitch for fuel.  The still is provided with an agitating roll 30. The heavy tar in tank 11 is blended with the pitch from the still by pumping it through line 34 to a mixing tank 37, the pitch being introduced through line 36.
