Regulation method for a chemical medium.

摘要

Plant permitting a changing chemical medium to be controlled and regulated to arrive at an optimum value of a predetermined function of physical or chemical parameters representing the medium, the function Y being related to the values of the parameters by a relationship of the form: <IMAGE> the said plant comprising: - sensors (5, 6) intended to supply the instantaneous value of each of the said parameters, - a scanning unit (26) allowing the value of the group of parameters to be recorded at uniform intervals, - a calculating unit (10) making it possible to determine the modification to be made to the said parameters to give an optimum value to the function Y, and - means for adjusting the said parameters controlled by the said calculating unit (10) to bring the value of the said parameters to the optimum. <IMAGE>
