regards the establishment of stand-by plants for anhydrous aluminum
chloride:
It has been planned to produce aluminum chloride from
aluminum metal in these stand-by plants, as in “A-Fall” [case of war]
one cannot reckon on receiving the quantities of raw material which the normal
production process requires, and because the method with aluminum metal is much
simpler.
In former years aluminum chloride was technically produced
from aluminum metal and chlorine in the Ludwigshafen plant of the IG; however,
owing to the development of new processes on a different raw material basis,
the technical development of this process did not go beyond relatively small
production units. The capacity of a single system amounts only to approximately
160-170 kilograms per day, so that for the production of 125 tons per month, as
it has been planned for instance for Huels, about 25 small production units
would have to be set up side by side. There is no doubt that it is now possible
to develop larger production units for the production of aluminum chloride from
aluminum metal and chlorine. The production of such larger production units
would of course mean a considerable lowering of the investment costs (estimated
to be approximately 40 percent) for the stand-by plant and a decrease of
personnel for the operation.
On the basis of our previous experiences,
gained by the technical execution of the process, we have designed plans for a
production unit of 1 ton per day of aluminum chloride. We now suggest that you
should give our firm a development order in this direction with a view to
placing the stand-by plants to be established in the future on as economic a
footing as possible.
The costs for the setting-up of an experimental
furnace with an estimated capacity of 1 ton per day of aluminum chloride are
estimated by us to be 60,000 reichsmarks. For 6 months operation period on a
trial basis, including further developments, we estimate an amount of 30,000
reichsmarks. The iron requirements of the plant would amount to approximately
30 tons of iron.
In order to take advantage of these experiments also
for the Huels plant, your decision on this matter would have to be given
immediately.
We therefore look forward to your opinion concerning our
proposal as soon as possible. |
