PROVISIONAL SPECIFICATION.
Apparatus for Clarifying Spent Liquor from Sulphate Ammonia
Plant.
WILLIAM DIAMOND, 10, Southfields Terrace, Pye Bridge, near Alfreton, Derby-
shire Analytical Chemist, do hereby declare the nature of this invention to
be as follows:-
:
The spent liquor is conducted into a square brick tank (a) which is below the
level of the sulphate ammonia plant. Conveniently situated is a pump, the
suction pipe of which is connected into the aforenamed tank (a) and the delivery
of the pump is connected to several large iron tanks (b, c, d, etc.), the connec-
tion pipe running along the top of the tanks (bc) branching from this pipe
At
are lengths of pipe fitted with taps leading into each tank (be d etc.).
one end of each of these tanks, there is fitted in the centre, one outlet pipe, &

one above the centre. These are connected into one main pipe (E).
pipe is connected to another tank (F) in which is fixed an agitator worked by a
belt & a driving engine. Erected above the agitator tank, and connected to it
by means of a pipe, is a small tank in which is dissolved aluminoferric cake
by water: a water supply is also connected to the tank: conveniently situated
is a pump, the suction pipe of which is connected to the bottom of the agitator
and the delivery pipe to a filter press. The filtrate is conducted into a brick
tank and then allowed to overflow into a small tank lined with glazed bricks.
The bottom of each of the tanks (be or d etc.) are tapered to one end also at
the bottom of each is fitted a pipe of large bore and running parallel with the
tank one end is fitted to the tank and the other is fitted with a treadle valve.

WILLIAM DIAMOND, Analytical Chemist, 10, Southfields Terrace, l'ye Bridge,
near Alfreton, Derbyshire, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:―
The spent liquor is conducted into a square brick tank M which is below the
level of sulphate ammonia plant. Conveniently situated is a pump the suction

page_text: pipe of which is connected into aforenamed tank M and the delivery of the
pump is connected to several large iron tanks A B C the pipe running along
the top, branching from this pipe is a length of pipe fitted with a tap leading
into each tank A B C. Fitted in the centre of the end of each tank A BU
is one outlet pipe fitted with a tap these are connected into one main K. This
main is connected to a tank D in which is fixed an agitator, worked by a belt
& driving engine. Erected above the agitator tank is a small tank E which is
connected to the agitator by means of a pipe fitted with a tap. In this tank
is dissolved aluminoferric cake by water. A water supply is connected to this
tank. To the bottom of the agitator is connected the suction pipe of a pump G
by means of a pipe L, and the delivery to the filter press X. The filtrate is
conducted by trough H into the drain.
For mode of precedure, the spent ammoniacal liquor is run into tank M, out
of which it is pumped into tanks A B C by pipe running along the top. As
one tank is filled the spent liquor is turned into the other, thus allowing
insoluble substances to deposit, when the spent liquor is cool is is conducted
by a tap out of each tank into main K, which carries it to the agitator D
where it is mixed with a quantity of aluminoferric solution, to clarify it, the
whole is then agitated, the mixed liquids are then pumped through filter press X
where the deposit remains & the clear liquid runs away down the trough H. It
can either be worked intermittent or continuously..
. Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed, I declare that what
I claim is:-
The design & method of process for clarifying spent liquor also the use of
aluminoferric as a reagent.
