Abstract: With the further development of national environmental protection work, CEMS has been widely used in refinery enterprises. Yet there are many problems existing in different stages of model selection, design, installation and debugging and daily operation. The key to ensure the stability of monitoring data is to accurately select the principles of instrument analysis according to the actual conditions. The refineries in particular must try to avoid the interference of hydrocarbons on the monitoring of sulfur dioxide. They should standardize the construction, lay pipelines correctly, avoid u-bend and prevent accumulated water from affecting the monitoring data. They should inspect and maintain carefully, identify and handle the faults during operation in time. They should select sampling holes and comparison monitoring holes correctly for the convenience of manual comparison monitoring. The objective of the above measures is to ensure the stable operation of the CEMS and the standard discharge data of pollutants.
