Abstract: 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.
