对凝析油脱汞主要方法进行了分析与评价，根据某气田凝析油特点及处理要求，提出凝析油脱汞现场试验方案，即化学吸附、汽提、汽提-化学吸附组合工艺，并完成凝析油脱汞试验装置的开发及设计。现场试验及应用效果评价表明，高含汞凝析油经汽提-化学吸附工艺处理后，凝析油中单质汞含量低于10 μg/L，总汞含量低于100 μg/L，处理效果较其他2种工艺好且成本较低。针对高含汞凝析油可采用汽提-化学吸附工艺进行脱汞。

Main methods for mercury removal from condensate oil are analyzed and evaluated.Based on the characteristics and treatment requirements of condensate oil from a certain gas field,a field test scheme for mercury removal from condensate oil is proposed,that is,a combined process including chemical adsorption,gas stripping,and gas stripping-chemical adsorption.The development and design of condensate mercury-removing test equipment is completed.Field test and application effect evaluation show that after high mercury-containing condensate is processed by the test device with gas stripping-chemical adsorption process,elemental mercury content in the condensate is less than 10 μg·L^-1,and total mercury content is less than 100 μg·L^-1.The treatment effect is better than the other two processes and the cost is also lower.The gas stripping-chemical adsorption process can be applied to remove mercury from high mercury-containing condensate oil.
