ABSTRACT:
The so-called float tar which floats on the stream of crude tar and ammonia water in the tar separator of a coking installation and which interferes with the clean separation of crude tar and ammonia water is removed by skimming the float tar off the crude tar and ammonia water mixture and subjecting the separated float tar to comminution and homogenization whereupon the homogenized tar product may be processed either separately or together with the bulk of the tar. An installation for use in the process comprises a tar separator in the form of an open top separator vessel, a channelled structure associated with the separator vessel, means provided in the separator vessel for skimming the float tar off the bulk of the crude tar and ammonia water and passing it into the channel of said structure, and a comminuting and homogenizing device which communicates with said channel through a grade drop.
