Abstract: The invention relates to a thermal vibro-electrostatic process for the purification of rock salt (NaCl), which may be used for purifying salt products or for separating the fractions resulting from processing salt-containing ores. According to the invention, the process provides for a preliminary separation of coarse impurities by electrostatically- and gravity-differentiated vertical displacement as a consequence of the field created between two electrodes (2 "minus" and 5 "plus") where NaCl-containing powder material is introduced, said material having a humidity ranging between 8 and 15% and a specific flow-rate of 1500 kg/h/m, a thermal treatment, drying of the rock salt in order to modify the electric permitivity thereof, conveyance and distribution of the pre-cleaned rock salt with a view to allowing it to be charged with electric loads within the field created between the surface of the conveyor bucket (3) and the high voltage electrode (2) connected to the ground potential. The non-uniform electrostatic field, having an intensity ranging between 900 and 1200 kV/m ensures the electric charge, the electric load density being of 80...120 niuA, the rock salt being vigurously agitated by the electrostatic and vibrating forces, resulting in the separation of certain impurities through the sieve meshes on the bucket inclined under an angle of 15...25^0. Further on, the purified rock salt is conveyed together with the remaining of impurities to the minimal intensity zone of the electrostatic field. In the discharge zone of the conveyor (3), the remaining impurities are less deflected by the electrostatic field and they move along a special discharge path, while the purified rock salt NaCl is more deflected by the electrostatic field and is completely separated and discharged along another path.

Abstract: What is proposed is a method for the cryogenic separation of air (AIR) in an air separation plant (100) having a main air compressor (2), a main heat exchanger (4) and a distillation colmnn system (10) having a low-pressure column (11) operated at a fITst pressure and a high-pressure column (12) operated at a second pressure, in which a feed air flow (a), which comprises all of the feed air fed to the air separation plant (100, 200), is compressed in the main air compressor (2) to a third pressure that is at least 2 bar above the second pressure, wherein a first fraction (c) of the compressed feed air flow (b) is cooled at least once in the main heat exchanger (4) and is expanded from the third pressure in a fITst expansion turbine (5), a second fraction (d) is cooled at least once in the main heat exchanger (4) and is expanded from the third pressure in a second expansion turbine (6), and a third fraction (e) is further compressed to a foOOh pressure, is cooled at le
