Patent ID: 11123701

Abstract:
A process including introducing, into a device, an aqueous fluid containing at least one inorganic salt, the water of the aqueous fluid being in supercritical conditions or close to the supercritical range in the device, and measuring the concentration or the amount of inorganic salt in the device, this measurement preferably being carried out before the entry of the inorganic salt into the device, Then bringing the inorganic salt into contact with an aqueous flow containing at least one hydroxide salt to obtain in the device an aqueous fluid mixture containing an inorganic salt and a hydroxide salt and adjusting the concentration or amount of the hydroxide salt as a function of the concentration or amount of the inorganic salt needed to at least partially solubilize the inorganic salt. Preferably the measurement of the concentration or the amount of inorganic salt leaving the device is also performed.
