Because of the influence of human living space caused by atmospheric pollution is becoming more and more serious, increasing supervision of environmental protection has become a pressing matter of the moment.Therefore, in recent years, Continuous Emission Monitoring System (CEMS) has been further extended application in refinery. This paper introduces the CEMS of SICK, which used in the project of NOx nitroso device, analyes the principle of CEMS transducer. This paper expounds the selection of various types of transducers of CEMS, and put forward the problems in the actual installation and construction of CEMS, in order to achieve the rational use of resources, the real-time monitoring function of the flue gas emission, in order to supervise the enterprises save energy to protect the environment .%由于大气污染对人类的生存空间造成的影响越来越严重，增加对环境保护的监管力度已成为当务之急。因此，近些年烟气排放连续监测系统（CEMS）在炼油厂的应用也得到了进一步推广。本文通过介绍西克麦哈克(北京)仪器有限公司（SICK）的CEMS在亚硝基制备装置NOx治理项目上的设计应用，对CEMS各种探头的原理进行了分析。阐述了CEMS各种探头的选型设计方案，并提出CEMS在实际安装及施工时该注意的问题，以达到合理利用资源、实现对企业的烟气排放的实时监测功能，监督企业做到节能环保的目的。
