含汞气田装置绿色检修清洗技术研究与应用

Research and application of green maintenance and cleaning technologyfor mercury-containing gas field equipment

汞及其化学物质均有剧毒,在含汞气田装置检修清洗的过程中,汞及其化合物的扩散会造成环境污染,严重威胁检修作业人员的职业健康。含汞气田装置清洗及汞防护一直是国内外面临的一大技术难题,目前也没有成熟的经验可供参考。以KS含汞气田装置绿色检修为例,革新了含汞容器清洗方法,优化了检修工艺流程,发明了环境汞及人体汞防护装置,最终形成了一套含汞气田装置绿色检修清洗技术。将该技术运用于含汞气田装置检修清洗工作,清洗时长明显缩短,清洗效果显著提升,环境汞浓度大幅降低。实践表明,该技术具有一定的经济、安全、社会价值,可为含汞气田装置的绿色、安全、高效检修清洗提供技术支撑。

Mercury and its chemical compounds are highly toxic.During the maintenance and cleaning process of mercury-containing gas field equipment,the diffusion of mercury and its compounds can cause environmental pollution,seriously threatening the occupational health of maintenance personnel.The cleaning and protection against mercury in such equipment remains a significant technical challenge both domestically and internationally,with no mature experiences to draw from.Taking the green maintenance of equipment in KS mercury-containing gas field as a case study,an innovative method for cleaning mercury-contaminated vessels was developed,the maintenance process was optimized,and new devices for environmental and human protection against mercury exposure were created.This resulted in a comprehensive green maintenance and cleaning technology for mercury-containing gas field equipment.Applying this technology has considerably reduced the cleaning time,enhanced the cleaning effectiveness,and substantially lowered the concentration of mercury in the environment.Site practices have shown that this technology holds economic,safety and social benefits,providing technical support for the green,safe,and efficient maintenance of equipment in mercury-containing gas field.
