Parametric studies of soil venting for remediation of benzene-contaminated soils

Research output: Contribution to conferencePaper

Abstract

Bench-scale laboratory experiments were conducted to evaluate the effectiveness of air stripping for in-situ remediation of benzene-contaminated soils. Several parametric studies were performed to evaluate the effect of soil grain size, air injection flow rate, and air inlet temperature on the benzene recovery efficiency. An increase in soil grain size produced a significant increase in benzene recovery efficiency especially during the early stages of air injection. After two hours of treatment, an increase in soil grain size from D50 = 0.31 mm to D50 = 1.20 mm resulted in an increase in benzene recovery efficiency from 49% to 65%. When the air flow rate was increased from 5 l/min to 10 l/min, the benzene recovery efficiency increased from 56% to 70% after four hours of venting operation. Maximum recovery of benzene was reached after approximately 37 hours of soil venting at the flow rate of 5 l/min and after approximately 24 hours at the flow rate of 10 l/min. Preheating of the air to 45°C at the inlet resulted in an increase in recovery efficiency from 70% to 90% after 5 hours of air stripping.
