Draw up a table for the material
balance of a rectification column
in that process of separation
hydrofluoric acid and water is
produced.
Starting composition is given as
HF – 25 mole; H2O – 35 mole.
Requirements to quality of
product (final composition):
content of HF in water – 1 mole,
and purity of hydrofluoric acid
are the theoretical absolute.
4
What is a driving force for the
mass transfer process?
5
Draw up a table for the heat balance of a device to produce
sulfuric acid from oleum and water. Considerations must be
given to the quantity of heat which is forming at production
acid and equal 3.25 k.J per day. Looses for a heating in
surroundings are equal 0.40 k.J per day. The heat to warm
up the constructive materials of the device is 1.15 k.J per day
6
What is a driving force for the heat
transfer process?
7
Draw up a table for the heat balance of the
desublimator in which process of recovery of
hexafluoride of uranium is produced, if the
condensation heat of UF6 is equal 2.5 k.J/day,
looses for heating in
surroundings are equal
0.3 k.J/day, heat to warm up
the constructive materials
of desublimator is 1 k.J/ day

Draw up a table for material
balance of the sorption column
in which process of separation
of threefluoride of bromine and
pentafluoride of iodine is
produced.
Starting composition:
IF5 – 0.65 mole; BrF3 – 0.74 mole.
Requirements to quality of
product: content of BrF3 in IF5 –
0.1 mole, and contamination of
BrF3 by IF5 can be 0.14 mole.

Draw up a table for the material balance
of the extraction column in which process
of separation substances of uranium and
thorium is produced. Starting flow rate
(recalculated on UO22+ and ThO22+):
UO2(NO3)2 – 2.15 k.mole/day; ThO2(NO3)2
– 1.22 k.mole/day. Flow rate of ThO2… in
stream i is 1.15 k.mole/day, flow rate of
UO2… in stream j is 2.0 k.mole/day
