APPLICATION
When nitric acid is added to the phosphate rock, the digester has a
temperature of about 60°C and the acid
strength is 60%.
At the evaporation stage the temperature is 180°C. Epizofoam FR has proved to be
very powerful defoamer in the manufacture of complex fertilizers produced from
the following important rock phosphates:
Kola Phosphate, USSR , Morocco Phosphate, Florida Phosphate, Granges Phosphate,
Sweden, Jordanian Phosphate Usually, foam is caused by carbonates in the
appetites out of five different rock phosphates mentioned above.
Florida phosphate and Morocco phosphate cause great foam problems. Quantities of
Epizofoam FR used in these two varieties vary between 0.05 to 0.1% on the weight
of rock, i.e. 500 grams to 1 kg of Epizofoam FR for 1 ton of rock is sufficient
to suppress foam. However, this quantity may change depending upon conditions
during operation. NPK fertilizers was found to be very effective in suppressing
foam formed during manufacture of NPK fertilizers. Generally foaming is, caused
due to the following factors:
a) Decomposition of Urea with phosphoric acid b) Presence of soot in the system.
c) Dissolution of rubber lining which gives rise to gasses d) Plant conditions
Foaming caused due to various reasons mentioned above can easily be suppressed
by dosing 0.005 to 0.05% of Epizofoam FR on the weight of scrubber
liquor/fertilizer slurry.
Sometimes, higher doses are, required when foaming is very severe. Dosing of
Epizofoam FR can be done from overhead tank or with the help of a plunger type
of pump.
ADVANTAGES
Epizofoam FR defoamer exhibits the following outstanding characteristics in
actual plant usage:
1. Lowers the surface and interfacial tension.
2. Significantly lowers defoamer cost per ton of acid produced.
3. Promote more complete reaction.
4. Does not affect rubber tank and hose lining.
5. Does not discolor or clog filter cloth.
6. Improves filtration and crystallization.
Note
According to our best knowledge and technical experiments, the above data is true and accurate. Regarding to variety of consumption procedures, it is recommended to evaluate the information before use.
