Identification and Elimination of Gross Error in Petrochemical Enterprise

Abstract:

The improved MT-NT combination method has solved the issue of failure or interrupted of solving when it is used in the Petroleum chemical enterprise production process. In this paper the judgment of the variable coordination credibility was added, corresponding processing was made in the measurement, and a more cautious handling was taken on the measured variable that may cause significant error. The experimental results show that this method is more suitable for application and actual production process. The MT-NT combination method has a higher accuracy and integrity in the detection of significant errors, with the advantage of both eliminating the defect of missing appreciable error and improving the calibration results. As a result, the method is more suitable for application and actual production process.
