“…The concentrations of BTEX and 16-PAHs were analyzed by a gas chromatography flame ionization detector (GC/FID) (Agilent 6890N). The details of the analysis method could be found in previous studies (Kuo et al 2014;Samaksaman et al 2015). Furthermore, ash samples were subjected to digestion with a mixture of acids (HCl/HNO 3 = 1:2) using a microwave-assisted digestion (CEM Mars 5).…”

“…Previous studies have investigated the effect of sand bed height tended to increase heavy metals collection (Lin and Yeh 2010), and the amount of sand bed in a fluidized bed reactor also influenced the removal efficiencies of heavy metals and particles (Nowak et al 2011). Because the ash composition of co-contaminated soil (up to 95 wt%) is significantly high (Samaksaman et al 2015), soil incineration led to elevating the sand bed (slag) height during thermal treatment. Results from earlier studies have suggested that the addition of inert materials such as clay, aluminum, silica, kaolinite was a way to increase the sources of alternative bed material (Kuo et al 2008) and could prevent any kinds of problems including combustion and removal efficiencies, pollutants, even improved hydrodynamics behaviors.…”

Thermal treatment of soil polluted by lube oil and heavy metals (cadmium, chromium, copper, and lead) was carried out by using a laboratory-scale incinerator. The effect of co-contaminated soil mixtures as fixed/fluidized bed media was studied with different ratios of sand bed amount to soil feeding. Additionally, the effect of soil moisture content on incineration system was further investigated. The reduction in air input altered the mode of fluidized bed to fixed bed which resulted in an increase in organic pollutants such as benzene, toluene, ethylbenzene, xylene, and polycyclic aromatic hydrocarbons. The combustion efficiency of fixed bed mode was observed to be relatively high at a lower ratio of sand bed amount to soil feeding, whereas high combustion efficiency was found in fluidized bed mode at a higher ratio of sand bed amount to soil feeding. Much higher concentration of organic pollutants in both gas phase and bottom ash is found under a higher soil moisture content. In addition, the increase in moisture content has resulted in an increase in lead, cadmium, and chromium in fly ash while copper was decreased. An important consideration is that the partitioning of heavy metals was randomly distributed in particle sizes of bottom ash. The highest concentration of heavy metals was deposited on fine-sized particle. The distribution of heavy metals in medium-sized and coarse-sized particles to form eutectic species might be produced by the soil-sand aggregation.

In this study, we investigated the removal mechanism of total petroleum hydrocarbons (TPH) from soil by microwave heating. TPH contaminated soil was investigated to determine the desorption behavior of five carbon number-based fractions of TPH. The applied operating microwave power density influenced the final temperature that was reached during heating. For low operating power density applications, microwave effectiveness was limited due to the soil’s dielectric properties, which exhibited a direct relationship with temperature variation. Soil particle distribution could be attributed to permeability, which significantly influenced the evaporation of contaminated soil during the microwave treatment. The results indicate that the activation energy was correlated with the influence of particle size. The removal efficiency of the coarse soil reached 91.1% at 15 min, whereas that of fine soil was low. A total of 30 min had passed, and a removal efficiency of 71.2% was found for the fine soil. Residual TPH concentration was decreased when irradiation time was increased with a removal rate dependent on soil temperature variation. The surface functional groups of the contaminated soil were influenced by microwave irradiation, and changes in the hydrocarbon fraction affected contaminant removal.

“…studied the impact of soil composition and final temperature (200-900 °C) on the weight loss of diesel-contaminated soil (with 2.5 wt% of diesel). Researchers have found that final temperature, treatment time and soil properties (e.g., soil texture) are the key factors of thermal remediation efficiencies(Falciglia et al, 2011) Samaksaman et al (2015). conducted a laboratory-scale thermal treatment of lube oil contaminated soil under 800 °C using fixed/fluidized bed and found that the addition of sand to polluted soil could enhance oil removal Samaksaman et al (2016b).…”

Drill cuttings are generated during the exploration and extraction of oil and natural gas. Due to the use of oil-based muds (OBMs) during drilling process, large amounts of oil-based drill cuttings (OBDCs) are produced. Such hazardous waste contains a relatively high content of petroleum hydrocarbons (PHCs). The effective removal of PHCs from OBDCs has attracted ix Acknowledgement This thesis reflects the final part of achievements that I have made in my M.Sc. study at the University of Northern British Columbia (UNBC). First and foremost, I would like to express my sincere gratitude to my co-supervisors, Prof. Jianbing Li and Prof. Min Zhao, for their patience, understanding, insightful instructions, and support throughout my study and research. Without their guidance and support, it would be impossible for me to complete this research. What I have learned from them will benefit my future career and life. Moreover, I would like to thank Prof. Ronald W. Thring for serving as my supervisory committee member. I greatly appreciate his insightful comments, guidance and discussions. I would like to express my appreciation to Erwin Rehl and Charles Bradshaw working in Northern Analytical Laboratory Service (NALS) at UNBC for their patience and help on developing and refining my analytical methods as well as on analyzing my experimental samples.
