化工设备泄漏检测与修复（LDAR）的方法研究
LDAR是国际先进的化工废气检测与修复技术，通过对化工企业生产全过程所涉及的反应釜、原料输送管道、泵、压缩机、阀门、法兰等易产生挥发性有机物VOCs的泄漏处，以检测与修复超过一定浓度的泄漏处，来控制泄漏对环境造成的污染。

Methods Research on chemical equipment of leak detection and repair (LDAR)
Abstract: This thesis mainly research equipment leak detection and repair methods.Equipment leak detection and repair (LDAR) is based on the potential, may periodically test equipment leakage, leak detection equipment and repaired as soon as possible, so as to reduce the toxicity of volatile organic compounds and organic atmospheric pollutant emissions, improve the reliability of craft, eventually reduce manufacturing costs, safety, and other products a control technology.
LDAR is an international advanced chemical waste gas detection and repair technology, based on the chemical enterprise production process involved in the reaction kettle, raw material conveying pipe, pump, compressor, valve, flange, etc are prone to volatile organic compounds VOCs leak, more than a certain concentration of leak detection and repair, to control leakage pollution to the environment.
Key Words: leak detection；reparation；volatile organic compounds；
chemical equipment.
