Objective
To construct a demonstration plant for the recovery of chrome sulphate from the tanning process, without heating. The organic substances remaining from this process, almost chrome-free, may be used for the simultaneous production of biogas and for heating.
The direct energy savings i.e. without making use of the organic residues, by this new recovery process are estimated at 1187 toe/year.
During the measurement phase of 18 months, the plant worked on average at 54% of its nominal capacity. The reason was mainly that the plant has only received about half of the expected quantity of tannery waste for treatment. This entailed that only about 50% of the possible energy savings could be achieved. The plant has worked satisfactorily so that the project is to be considered as a success.
The design capacity of the recovery plant is : treatment of tannery wastes equivalent to a constant of 2070 Kg/d of Cr2O3 to recover about 2050 Kg/d of Cr2O3, corresponding to about 21000 kg/d of chrome salt solution to be reused in the tanneries.
The wastes entering the plant are approximately:
- 380 t/d exhausted chrome salt solution of 0.3% - 0.8% Cr2O3 content;
- 29 t/d of precipated sludges of 1% -2% Cr2O3 content;
- 5.4 t/d of coke of dewatered sludge of 8% - 12% Cr2O3 content.
The wastes are processed using chemical and mechanical processes in various stages with no heat consumption, to recover basic chrome sulphate for reuse in the tanneries.
The cost of the project (excluding the demonstration phase) amounts to LIT
3 000 000 000. Further plants of this kind could cost about LIT 1 700 000 000.
