The process involves treating the chlorinator waste with oxygen in a fluidised bed under conditions which promote the conversion of metal chlorides to metal oxides and discourage the oxidation of carbon contained in the waste. Suitable conditions include a bed temperature in a range from 400 to 700° C., a superficial velocity in a range from 0.2 to 1 metre/second and stoichiometric ratio, R, in a range from 0.2 to 1.2.

    Abstract: A method of making nanosized copper (I) compounds, in particular, copper (I) halides, pseudohalides, and cyanocuprate complexes, in reverse micelles or microemulsions is disclosed herein. The method of the invention comprises (a) dissolving a copper (II) compound in the polar phase of a first reverse micelle or microemulsion, (b) dissolving a copper (II) to copper (I) reducing agent or a pseudohalide salt in the polar phase of a second sample of the same reverse micelle or microemulsion, (c) mixing the two reverse micelle/microemulsions samples to form nanometer sized copper (I) compounds and (d) recovering said nanometer sized copper (I) compounds. The present invention is also directed to the resultant nanosized copper (I) compounds, such as copper (I) chloride, copper (I) cyanide, and potassium cyanocuprate complexes having an average particle size of about 0.1 to 600 nanometers.

  • Publication number: 20030211031
    Abstract: To produce ferric chloride, pickle liquor containing ferrous chloride and fortified with sufficient HCl is converted to ferric chloride in the presence of oxygen in a tower at a temperature above 132° F. The ferric chloride solution from the tower is subjected to evaporation so as to increase the concentration of the ferric chloride. The resultant concentrate is recycled into the tower until a concentration of about 40% by weight ferric chloride is obtained. A gas phase from either or both of the tower and the evaporator is scrubbed in order to remove HCl which can be used to fortify the pickle liquor.

  • Patent number: 6602482
    Abstract: A process for separating metal chlorides from a suspension of metal chlorides in chlorosilanes, in which the suspension is filtered under pressure in the absence of air and moisture forming a filter cake, which is granulated and passed to a dissolution zone where the metal chlorides are dissolved to form an aqueous metal chloride solution. The invention also relates to a filtration and dissolution apparatus for this process, and to an apparatus for introducing the crude reaction gas into a circulated suspension of metal chlorides in chlorosilanes, thus producing a feedstock for the process.

  • Patent number: 6524546
    Abstract: A new process for producing calcium chloride and other metal halides from the carbonates, bicarbonates, oxides of these metals. The process utilizes the discovery that hydrogen halides, when used in a true or conventional fluidizing medium in shallow beds of the aforementioned solids at moderately elevated temperatures in a continuous counter current process results in the conversion of the metal carbonates, bicarbonates, and oxides, into metal halides and carbon dioxide gas and/or water vapor. The process is carried out in a series of true or conventional fluidized beds preferable but not necessarily arranged in a vertical configuration so that the solids flow downward due to the fluidized process and the hydrogen halides flow counter currently in an upward direction producing metal halides at the bottom and pure carbon dioxide gas and/or water vapor at the top.
