PUBLIC ABSTRACTThe drilling and operation of gas/petroleum exploratory wells and the operations of natural gas and petroleum production wells generate a number of waste materials that are usually stored and/or processed at the drilling/operations site. Contaminated soils result from drilling operations, production operations, and pipeline breaks or leaks where crude oil and petroleum products are released into the surrounding soil or sediments. In many cases, intrinsic biochemical remediation of these contaminated soils is either not effective or is too slow to be an acceptable approach. This project targeted petroleum-impacted soil and other wastes, such as soil contaminated by: accidental release of petroleum and natural gas-associated organic wastes from pipelines or during transport of crude oil or natural gas; production wastes (such as produced waters, and/or fuels or product gas). Our research evaluated the process designated Chemically-Accelerated Biotreatment (CAB) that can be applied to remediate contaminated matrices, either on-site or in situ. The Gas Technology Institute (GTI) had previously developed a form of CAB for the remediation of hydrocarbons and metals at Manufactured Gas Plant (MGP) sites and this research project expanded its application into Exploration and Production (E&P) sites. The CAB treatment was developed in this project using risk-based endpoints, a.k.a. environmentally acceptable endpoints (EAE) as the treatment goal. This goal was evaluated, compared, and correlated to traditional analytical methods (Gas Chromatography (GC), High Precision Liquid Chromatography (HPLC), or Gas Chromatography-Mass Spectrometry (CG-MS)). This project proved that CAB can be applied to remediate E&P contaminated soils to EAE, i.e. those concentrations of chemical contaminants in soil below which there is no adverse affect to human health or the environment. Conventional approaches to risk assessment to determine "how clean is clean" for soils undergoing remediation have been based on total contaminant concentrations in soil, as determined by laboratory extraction methods that use vigorous physical and chemical procedures. Numerous data collected from bioavailability studies in this study and others carried out by GTI and other organizations conducted on contaminated soils and sediments continue to show that not all contaminants are available to environmental receptors including man or ecologically forms. In short, there exist fractions of contaminants in soil that cannot be released from the soil matrix by normal means. These sequestered contaminant fractions should not be considered a risk to human health or the ii environment. This project focused on CAB technology to treat soil contaminants to these acceptable levels. Therefore, the primary objective of this project was to determine what these contaminant levels are and to reach or exceed cleanup standards using CAB. These determinations were demonstrated and verified using toxicity and chemical mobility tests. Based on GTI's experience with a fo...

“…The substrates include aromatic hydrocarbons and other compounds such as amines, phenol and substituted phenols, polycyclic aromatics, chlorinated hydrocarbons and more complex molecules like dyes, pharmaceuticals, alcohols, mineral oils, etc. Lou and Lee [3] used Fenton's reagent to destroy benzene, toluene and xylene (BTX). Almost complete removal was achieved within short time (ten minutes).…”

Abstract:Effectiveness of the Fenton's reagent for partial degradation of diethanolamine (DEA) prior to biological treatment is investigated. The effects of the major process parameters on the time evolution of COD, an indicator of the extent of degradation, were measured. The DEA concentration ranged from 800 to 16,000 ppm, in consideration of the COD of real effluents of natural gas processing plants. The initial reaction rate was a strong function of the feed amine concentration. About 70-80% of the ultimate COD removal could be achieved within three minutes. The pH of the medium was varied over 1-4; the best results were obtained at pH 3.The effectiveness of a hybrid scheme of advanced oxidation followed by biodegradation was explored. Activated sludge from a local wastewater treatment pond was used. Fast COD removal of the partially degraded DEA was achieved within a day. Biodegradation of pure DEA was much slower, apparently because of the acclimatization time of the microbes.

“…The relation between DRE of BTX and H202 is shown in Figure 14 and shows that at a fixed pH and Fe 2 +, the DRE of BTX increased almost linearly with increasing 11202 concentration till 60 mg/I, and with an increase in concentration of H202 the DRE of BTX remained at 80% to 90%, showing zero order reaction. (Lou and Lee, 1995) As proposed by Harber and Weiss (1934), which may be due to the fact that at lower H 2 0 2 concentrations and fixed Fe 2 +, the oxidation approaches second order. But when the ratio of H202/ Fe2+ increases, the reaction kinetics approach zero order and the reaction process depends on the competition between hydroxyl radical and superoxide radical.…”

“…At Fe2+ > 600 mg/L, the DRE of BTX reached the maximum value of approximately 82% for benzene and toluene and 73% for xylene. Lou and Lee (1995), found that the DRE of BTX caused by Fenton's Reagent cannot be further raised due to lack of available H202, the H202 was consumed rapidly and DRE of BTX were minimum, thus it suggests that reaction in equation 99 is very important.…”
