Study on the Influence Radius and Factors of Gas-Phase Extraction of Silty Soil in Retired Refineries
Using project pilot data,the effects of environmental temperature,soil moisture content,and extraction negative pressure on gas-phase extraction efficiency are analyzed.The research results indicate that the maximum impact radius of the sandy soil area is about 6 m;the environmental temperature,soil moisture content,and extraction negative pressure all have a significant impact on the gas-phase extraction efficiency.
