摘要： An apparatus for carrying out chemical reactions comprising a pair of substantially vertical pipes connected to one another adjacent their bottoms, means for supplying liquid to one of said pipes to maintain therein a liquid level, an overflow pipe connected to the second of said pipes at a level below the liquid level in said one pipe, and means for introducing at least one reactant to said one pipe below the liquid level therein, whereby the reaction is able to proceed under the pressure of the column of liquid in said one pipe, liquid and reaction product being continuously withdrawn. A heat exchanger may connect the two pipes adjacent their lower ends so that hot liquid in the second pipe can be cooled and recycled to the first pipe. The apparatus is especially suited for the reaction of ammonia and hexafluorosilicic acid to produce ammonium hexafluorosilicate.

摘要： Apparatus for the continuous dehydration of aluminum fluoride hydrates consisting of a fluidized-bed furnace with a cylindrical furnace jacket and a perforated plate just above the base, a lid to which gas-heated jacket radiant tubes are fixed reaching vertically almost to the said plate each of the tubes being closed at one end and having a concentric inner tube with a burner in the interior and being of almost the same length as the jacket radiant tube as well as open at the bottom so that combustion gas issuing from said burner in the interior of said inner tube flows upward in the tip of the outer tube after a change of direction of 180*. Thus both the fluidized bed outside the jacket radiant tube and, via a recuperator, the air passed to the burner are warmed.

摘要： A PROCESS FOR THE CONTINOUS CONVERSION OF HYDRATED HALIDES INTO ANHYDROUS SALTS, WHICH COMPRISES PRE-CALCINING THE MOIST HYDRATE IN A FIRST STEP BY HEATING IT WITH VIGOROUS AGITATION TO A TEMPERATURE AT WHICH THE TOTAL SURFACE MOISTURE AND PART OF THE CRYSTAL WATER ARE REMOVED, AND THEREAFTER FURTHER HEATING THE PRE-CALCINED SALT IN STEPWISE OPERATION IN A GENTLY MOVING LAYER UNTIL THE TEMPERATURE FOR COMPLETE CALCINATION IS INTRODUCED BRINGING ABOUT THE MOVING ACTION, DRY GAS IS INTRODUCED INTO THE LAYER OF PRE-CALCINED SALT WHILE IT IS BEING FURTHER HEATED FOR COMPLETE CALCINATION, SAID GAS ALSO SERVING FOR ENTRAINING THE STEAM FORMED DURING THE DRYING PROCESS. THE INVENTION FURTHER RELATES TO AN APPARATUS FOR CARRYING OUT THE CALCINATION.
