Ammonia converter production optimization method based on data excavation technology

Abstract

A production optimization method of an ammonia synthesizer which is based on the data mining technology belongs to a research frontier of the cross discipline field such as chemical engineering, system engineering, data mining and the like. The invention combines production characteristics of ammonia synthesizers, in accordance with parameter data and analytical measurement data of history production technology of the ammonia synthesizers which are gathered by the distributed control system, namely DCS, production and optimization target of the ammonia synthesizers and mathematical models between the relative technological parameters are established by utilizing the data mining technology. And real time data which are produced by the ammonia synthesizers are input in the mathematical models which are established, production status of the ammonia synthesizers are assured by the models, and models establishing and maintenance, working order diagnosing, target predicting, and optimum operation guide of ammonia synthesizers are achieved. And the ammonia synthesizers are operated under optimum state, and production capability and control level of the device are improved. The method has the advantages of safety and reliability, small risk, low cost and easy popularization.

Description

technical field [0001] The invention relates to a production optimization method for ammonia synthesis equipment based on data mining technology, which belongs to the research frontier of interdisciplinary fields such as chemical engineering, system engineering, and data mining, and covers production process optimization models and model maintenance, real-time monitoring of production status, and production engineering. Real-time diagnosis of conditions and optimization of production process parameters. technical background [0002] Petroleum and chemical enterprises are the basic pillar industries of our country and occupy a pivotal position in our national economy. However, compared with the production level of the world's petrochemical industry, my country's petroleum and chemical industry still has a big gap. For example, the cash operating expenses required for processing one ton of products reflect the production cost level of enterprises. In 2003, the world’s average...
