Gas migration simulator



 

180050

Station with weighable groundwater lysimeter

(Patent - No.: 199 07 462)

 

Function principle:

The Gas-Migration-Simulator has been designed for the close investigation of soil-gas migration pro-cesses under quasi in situ conditions. Soil-gas radon concentration can be used as an indicator for subsurface NAPL contamination. This contamination give rise to anomalous low soil-gas radon concen-trations in the close vicinity of contamination. The reason for this decrease in the soil-gas radon con-centration is the good solubility of radon in NAPLs, which enables the NAPLs to accumulate and ‘trap’ part of the radon available in the soil pores.

 

Lysimeter station in container design 

  • Dimensions: 3,5 x 3,5 x 2,5 m
  • Weight of the station: 1.600 kg
  • Soil weight / single vessel: up to 5 t

 

Application possibilities: 

  • Detection of soil contamination for facing risk assessment at polluted industrial sites and military bases; subsurface contamination by non-aqueous phase-liquids (NAPLs)
  • Examination of the migration of dump gases or withdrawing natural gas at underground leakages
  • Qualification test of sediment layers as underground gas storages
  • Examination of the Radon migration in soils
  • Special measuring equipment regarding the project aim
