METHOD OF PRODUCTION OF A SALINE CONCENTRATION Russian patent published in 2004 - IPC

FIELD: inorganic chemistry; petroleum industry; production of saline concentrates. SUBSTANCE: the invention is pertinent to an inorganic chemistry, in particular to methods of production of saline concentrates from natural mineral waters, that first may be used for production of inorganic drilling chemical agents acting as regulators of density of flushing fluids and inhibitors of hydration and dissolution of the rock-forming minerals. The method of production of a saline concentrate provides for intake of a mineral water from a borehole and its processing. The mineral water being delivered from the borehole is gathered in a holding tank, injected with the help of a pump through a sprayer in a drying chamber, where drying agent is discharged under pressure as a counter flow with the help of the ventilating fan. In the capacity of the drying agent they use a furnace gas or air with temperature of 350-400 C. Then the process of crystallization and a drying of the inorganic salts present in water takes place and the inorganic salts in the form of a fine powder transported into a collector. The waste drying agent with the help of the second ventilating fan is in succession directed into the cyclone separator and a bag filter and further in the atmosphere. Then they open the gates of the cyclone separator and the bag filter and the saline concentrate is poured on the endless screw. The target product is transported into the collector, passed through the batcher and packaged in the moisture proof containers. Technical result: production of a multi-component saline concentrate. EFFECT: the invention allows to produce a multi-component saline concentrate. 1 dwg, 4 tbl, 2 ex
