    Abstract: The present invention is directed towards a process for preparing a nickel composite hydroxide with a mean particle diameter in the range from 3 to 20 µm (d50) comprising the step(s) of combining
    (a) an aqueous solution of water-soluble salts of nickel and of at least one of cobalt and manganese, and, optionally, at least one of Al, Mg, B, or transition metals other than nickel, cobalt, and manganese,
    (b) with an aqueous solution of an alkali metal hydroxide and
    (c) with an organic acid or alkali or ammonium salt of an organic acid or an anhydride of an organic acid wherein said organic acid whose nickel(+II) salt has a solubility of 1g/l or less in water at 20°C and, optionally, with
    (d) an aqueous solution of alkali metal aluminate.

    Abstract: A computer-implemented method for controlling and/or monitoring equipment (110) of a chemical plant is proposed. The method comprises the following steps:
    a) specifying at least one parameter of a production process to be optimized;
    b) receiving input data via at least one input channel (126), wherein the input data comprises operating conditions of the production process, physical properties of a plant equipment layout, and at least one predicted parameter determined from a physico-chemical white box model (128), wherein the physico-chemical white box model (128) comprises at least one thermodynamics model (130), at least one solid formation model (132) and a computational fluid dynamics (CFD) based numerical simulation (134);
    c) optimizing the specified parameter via at least one processing device (138), wherein the specified parameter is optimized by adapting the operating conditions of the production process and/or the physical properties of the plant equipment layout based on the predicted parameter.
