Experimental Study on Adsorption Capacity of Natural Gas Odorant Tetrahydrothiophene in Soil and Relevant Influencing Factors

Abstract:

According to the practice of city gas odorization, the technological thought that the diffusion behavior of natural gas in soil was indirectly reflected by the adsorption capacity of tetrahydrothiophene (THT) as an odorant of natural gas in soil was put forward and explored. The adsorbed amount of THT in soil samples by gas chromatography-mass spectrometry (GS-MS) with purge and trap was determined. The impact of four parameters (namely gas leakage, water content, particle size and texture of the soil) on the adsorption properties of soil was then quantitatively analyzed. The experimental results showed that at initial stage of adsorption, the adsorption capacity of THT in soil sample was linear positively correlated with gas leakage and was negatively correlated with water content of the soil and there were no significant differences between particle size and texture of the soil and the amount of THT.
