A system selecting a process key factor in a commercial chemical process, includes: 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 variable 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.

A method for producing olefins using a circulating fluidized bed process, includes: supplying a propane-containing hydrocarbon mixture and a dehydrogenation catalyst into a riser, which is a fast fluidization regime, to cause a dehydrogenation reaction; separating, from a propylene mixture, the catalyst which is a product of the dehydrogenation reaction; removing unseparated hydrocarbon compounds remaining in the catalyst separated in the separating; continuously regenerating the catalyst by mixing the catalyst stripped in the removing with a gas containing oxygen; circulating the catalyst regenerated in the continuously regenerating to the supplying and resupplying it into the riser; and preparing propylene by cooling, compressing, and separating the propylene mixture which is a reaction product separated in the separating.
