| Abstract: | The concept of "slop-over value" is proposed based on pattern recognition clustering method.A method to calculate slop-over value is presented according to the relationship between operation class and objective class.The exception condition is detected on line by tracking slop-over value with statistical process control method.The proposed method has been applied in the exception detection of an ammonia synthesizer(80,000 tons per year) with satisfactory results. |

| Keywords: | statistical process control pattern recognition slop-over value ammonia reactor |
