摘要： Process for precipitating a carbonate or (oxy)hydroxide comprising nickel from an aqueous solution of a nickel salt wherein such process is carried out in a vessel comprising (A) a vessel body, (B) one or more elements that control the hydraulic flow of the slurry formed during the precipitation and that induce a loop-type circulation flow, and (C) a stirrer whose stirrer element is in the vessel but located separately from the element(s) (B).

摘要： 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) for predicting a precipitation process; 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.

摘要： Described herein is a process for making a nickel composite hydroxide with a mean particle diameter d50 in the range from 3 to 20 μm including 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) an aqueous solution of an alkali metal hydroxide and
(c) an aqueous solution of alkali metal (bi)carbonate or ammonium (bi)carbonate in the molar ratio of 0.001:1 to 0.04:1, and, optionally,
(d) an aqueous solution of alkali metal aluminate,
in a continuous stirred tank reactor or in a cascade of at least two continuous stirred tank reactors.-
