含汞气田汞污染控制技术研究

Research on Mercury Contamination Control Technology in Mercury-containing Gasfields

痕量组分汞可能出现在大多数天然气气藏中。汞及其化合物均是剧毒物质,在含汞天然气处理过程中可能危害操作人员健康、腐蚀管线设备以及污染环境。针对某气田含汞天然气处理工艺,分析汞在天然气处理过程中分布情况,评价汞对天然气处理工艺及环境的影响,提出了含汞气田汞污染的控制技术以及防护措施,对降低含汞气田开发风险、保护人身健康及防止环境污染具有现实意义。

Trace component mercury may exist in most of the natural gas reservoirs.Mercury and its compounds are highly toxic substances,which may threaten the health of the operators,corrode pipelines and equipments,and contaminate the environment during the process of mercury-containing natural gas treatment.According to mercury-containing natural gas treatment process of certain gasfield,this paper analyzes the distribution of mercury in natural gas process,evaluates the influence posed by mercury on natural gas treatment process and the environment,and presents the control technology and protective measures which have practical significance to reduce the mercury-containing gasfield development risk,protect human health and prevent environmental pollution.
