Abstract: To eliminate the limitation of the traditional method of statistical check and linear planning treatment, the existing techniques of measurement data correct in petrochemical process were analyzed firstly. Then the issues of data classification, error detection and data correction were investigated. Furthermore, the modified time series method was proposed for typical petrochemical equipments. The basic idea, probability model and characters of the method were stated. The method was applied to the large petrochemical equipment and measurement data correct, and it is shown that the shortcomings of the traditional method of data correction have been overcome.

Key words: data correct, error detection, modified time series method
