Wherein: ρH2OSample liquid mist content in gas, g/m3；
V0The volume of dehydrating agent, ml；
ρ-dehydrating agent density, g/ml；
x1Tracer ion concentration in dehydrating agent after absorbing liquid mist, ppm；
x0Sample the tracer ion concentration in gas, ppm；
V1Sample the sampling amount of gas, m3。
10. according to the method described in claim 9, it is characterized in that, the dehydrating agent is triethylene glycol；The tracer ion is three
Valence iron ion.
