SYSTEM AND METHOD FOR SELECTING PROCESS KEY FACTOR IN COMMERCIAL CHEMICAL PROCESS

WIPO Patent Application WO/2022/231282

A1

The present invention relates to a system and method for selecting a process key factor in a commercial chemical process, which enable the optimization of an operation condition by efficiently selecting a key factor affecting a change in catalytic activity according to a process operation condition, and comprises: a data extraction unit that extracts tag data in units of a set period; an outlier discrimination unit that discriminates and aggregates outliers by tag by using an outlier extraction reference master; an outlier processing unit that generates an input mart draft excluding the outliers; a derived variable generation unit that generates derived variables for each tag, and generates an advanced input mart having the derived variables added thereto; a yield calculation unit that backs up the result of calculation of a yield by realizing a target value via exclusion and correction of the outliers; and a key factor extraction unit that extracts a yield key factor by calculating importance of each tag, and backs up importance data for each tag.
