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： A process comprising: (a) distilling a melt comprising crude alkanesulfonic acid to completely or partly remove low boilers, wherein the low boilers are drawn off at the top of a distillation column or of a one-stage evaporation apparatus and a material stream comprising alkanesulfonic acid, high boilers and residual low boilers is withdrawn at the bottom of the distillation column or of the one-stage evaporation apparatus, (b) sending the stream comprising alkanesulfonic acid, high boilers and residual low boilers into a melt crystallization as the starting melt to obtain crystals formed from the alkanesulfonic acid, hydrates of the alkanesulfonic acid or a mixture of both suspended in mother liquor, (c) performing a solid-liquid separation to remove the crystals from the mother liquor, and (d) optionally washing the crystals to remove mother liquor adhering to the crystals.
