through a pipe line into the top Of
the tower" standing on the end Of
the still as described above.
Underneath the Still is n furnace,
running the full length of the still,
and with n slight draft through it
which carries the heat all around 1t
and up through the crooks" in the
tower resting on its top at the rear
end. The crude oil, you will re-
member, is being pumped from the
heat-exchanger and is trickling down
through the crooks against the vol
ume Of heat rising from the furnace
heated still below.
This heat is so great that a large
part OF the crude oil is converted into
n vapor, or gas, in the top part Of
the tower. and passes off through
the vapor line Ia 10-inch pipe) to
the condenser boxes located at the
rear of the still, and elevated to a
level with the top Of the tower.
OF these condenser boxes there are
two: one above, the other immedi-
ately beneath. They are oblong steel
25 feet from The ground. and within
them are coils of two inch pipe.

gasses are the first condensed. and
the fluid therefrom passes out through

From these condenser boxes the

into the receiving house, where it
flows in different streams through
glass-sided boxes with sliding tops
