PROCESS AND APPARATUS FOR THE
SEPARATION OF SO-CALLED FLOAT TARS
ABSTRACT OF THE DISCLOSURE
The so-called float tar which floats on the
crude tar in tile tar separator and is a bothersome by-
product is separated from the mixture of crude tar and
water formed in the collector of the separator of a cok-
ing installation and the separated float tar is then sub-
jected to comminution and homogenization whereupon the
homogenized product may then be processed either separately
or together with the bulk of the tar.
An installation for use in the process comprises
a tar separator, an open circulation or collector vessel
forming part of said separator, a channel associated with
said tar separator, means provided in said circulation
vessel for separating the float tar from the bulk of the
crude tar and passing it into said channel,and a comminut-
ing and homogenizing device which communicates with said
channel through a grade drop.
