Mr.. Michael has recently studied

1T is well known that the tar ex-
tracted at gas works contains large
amount of water, in many cases as
much as Is per cent. The separation
of this water from the tar is essential
for most purposes to which the latter
is put, and on that account it is fire.
quently the custom to allow the ma
terial to remain in wells for some time,
so that the water has an opportunity
of rising to the surface. Recently
more rapid process has been introduced
to bring about the separation, a process
identical with that of Swimming milk
in a centrifugal separator. The fresh
tar is heated to a temperature of about
90 degrees to reduce it's viscosity and
then placed in centrifugal machine
revolving at an enormous velocity. The
tar being heavier than the water presses
against the inside of the vessel, leaving
the water nearer the center, where it
is SKINNED off by projecting tubes.
