PROCESS FOR THE IN SITU RECOVERY OF CALCIUM SULFATE HEMIHYDRATE AND/OR CALCIUM SULFATE (ANHYDRITE) FROM THE SCRUBBER UNITS OF A WET FLUE GAS DESULPHURATING PLANT

In the process described above, using an absorbing agent rich in calcium and/or magnesium, the concentration of the washing suspension is set at a value of at least 50, preferably of at least 500, expressed in mg/m by the ratio between the chloride concentration of the aqueous phase of the washing s...
