Paper Number: PETSOC-97-37
... Abstract Dicyclopentadiene (DCPD) is considered a pollutant due to its strong, persistent odor. Thirty five bacterial species were isolated from soil contaminated with C5+, which consists of low molecular weight hydrocarbons such as benzene, toluene, styrene, cyclopentadiene...

... implementation are: limitations for treating multiple contaminants within a single waste, slow reaction rates, bioavailability limitations, and conversion of some contaminants to more toxic metabolites. This paper presents five innovative biotechnologies with examples of their use in the fossil...

... aerobic conditions, all tests showed significant reduction in diesel range (C-C 30 ) TEH-contamination. The intrinsic control was least effective, but still showed 66% TEH reduction at 5 °C. The biostimulated soil performed the best, allowing 86% TEH reduction. The bioaugmented soil and surfactant treated...

... Abstract Remediation of contaminated soil, particularly flare pits, in oilfield sites has become a focus of increasingly stringent environmental legislation. These earthen pits consist of soil mixed with hydrocarbons, water, salts, and metals. Current remediation techniques such as biological...

.... The plotmay therefore be used in a number of environmental investigations in thepetroleum industry. As an example, it was shown that a larger area, initiallythought to be contaminated by mercury as a consequence of oil and gasoperations, was in fact only marginally contaminated. The chondrite plot wasused...

... Abstract Concern regarding the environmental implications of decommissioning major industrial facilities has been growing in recent years. Long term plant operations can lead to substantial on-site and off-site contamination problems and decommissioned sites must be left in an environmentally...
