Abstract: The flare system is a control measure for petrochemical, metallurgical and other industries to deal with the flammable and harmful gases generated or remaining in the production process. It is an important guarantee for ensuring the safe operation of process equipment, and reducing environmental pollution. However, CO₂, NO_x and other incompletely combusted organic matter emitted by flare combustion are still important causes of environmental pollution. At present, there is still no mature standard for controlling flare emission in China. Therefore, the formation of standard specifications for flare emission and control has become an important part of green ecological construction. This paper expounds the systematic composition, classification and emission characterization factors of the flare, and compares the flare standards in foreign countries and regions, such as the US EPA, southern California, the European Union, and other regions with the domestic flare standards through the comparison and analysis of classification and system composition of the flare, the control of gas flow and heat value, the pilot flame and combustion flame detection and monitoring, emissions detection and monitoring, etc. This paper puts forward some suggestions on the basic framework of Shanghai flare emission control standards and regulations. The framework is based on the statistical analysis results of the flare in Shanghai, which mainly includes the following aspects:(1) To monitor the flow and pressure of gas discharge, control the ratio of gas discharge and auxiliary gas, and make the calorific value of combustion gas reach the range of complete combustion. (2) To monitor the ignition flame and combustion flame, ensure the flare's operation. (3) To monitor the visible emissions of the flare. (4) To strengthen the intensity of supervision of the flare, regular inspection and maintenance.
