ABSTRACT:
A method for providing improved estimates of properties of a chemical manufacturing process is disclosed. The method employs a process model that includes, or is modified by, scores or other gains obtained from the mathematical transformation of data obtained from an on-line analyzer. Chemical manufacturing processes using the method also are disclosed.
