Abstract
A method for controlling a chemical process, by preparing methanol, hydrogen sulfide, methyl mercaptan, hydrocyanic acid, acrolein, 3-methylthiopropionaldehyde, 5-(2-methylmercaptoethyl)-hydantoin, methionine, a salt of methionine, and a derivative of methionine. The method includes providing a training set TS, wherein TSis process values PVand process values PVbeing correlated to one another, and/or laboratory values LVand process values PVbeing correlated to one another. The method includes training a processing unit on the training set TSto identify a pattern of correlation between one or more measured process variables and at least one process variable. The method includes developing a calibration function CFfor a calibrated soft sensor from the identified pattern of correlation and predicting at least one operating parameter for the chemical process as an approximation to LVand/or PV. A system for controlling a chemical process.
