10cm。
Mercury removal agent 6 when in use, is filled up multiple strings by the above-mentioned adsorption tube structure for natural gas mercury-removing agent performance evaluation
In the adsorption tube 1 connect, injecting mercurous natural gas from the air inlet 41 of inlet suction port 4, (mercury content of the mercurous natural gas of injection is
Can be detected by instrument), when natural gas passes through adsorption tube, the mercury in natural gas can be by the active material in mercury removal agent
(such as copper sulfide) is adsorbed, and after natural gas passes through each section adsorption tube 1, mercury content can be reduced constantly, by adsorbing in every section
The variation of the outlet of the sampling valve 3 detection natural gas mercury content of pipe can study the performance of mercury removal agent (before each section absorption tube coupling
Natural gas mercury content after natural gas mercury content and section is can be detected by instrument, in the case where known air inflow,
The amount for the mercury that mercury removal agent is deviate from can be conversed), obtain the performance evaluation of mercury removal agent.
