Increased Oil Recovery

The microwave thermal conversion process of oil sludge was studied. It was found that the microwave thermal conversion process of oil sludge consisted of 5 stages: rapid heating, microwave drying, microwave hydrocarbons evaporation, microwave pyrolysis and microwave calcining. Using the residue produced from the microwave thermal treatment of oil sludge as a microwave absorbent can significantly accelerate the conversion. However, it does not show significant effect on the features of microwave thermal conversion. Meanwhile, the addition of residue at appropriate percentages increased oil recovery rate. The non-condensable gases consist of H2 and C1~C5 hydrocarbons. The recovered oil was mainly produced at microwave evaporation and microwave pyrolysis stages, consisting of 89% light oil and 11% heavy oil.

ABSTRACT Coastal salt-marsh vegetations are directly exposed to accidental marine pollution by oil spill, as it was the case in winter of the year 2000 following Erika tanker oil spill in France. As petroleum is incorporated in sediment, it tends to coat aerial parts of plants. Among fuel hydrocarbons, polycyclic aromatic hydrocarbons (PAHs) are the most toxic compounds known in marine organisms. Although their low water solubility, they can be taken up and bioaccumulated by plants. This work was conducted to determine whether PAHs, like naphthalene, phenanthrene, pyrene and benzo(a)pyrene, present in artificially fuel contaminated soils are transferred or not to aerial part of the coastal and edible plant, Salicornia fragilis. Sediments were mixed up with N°6. heavy fuel oil. Young plants of Salicornia were sampled in spring at the “Aber du Conquet” (Finistère, France), and cultured artificially in three different mixture conditions of oil and sediment: 0.2%, 2% or 20%. Two durations of culture were tested: one or five weeks. At the end of the culture, shoot are then cut off and PAHs concentrations were determinate by (GC-MS). Results showed that whatever the time of exposure and the concentrations of fuel oil in soil, significant PAHs concentrations were measured in Salicornia tissues. Phenanthrene and pyrene are the most abundant compounds. The particular morphology of Salicornia plants and the absence of PAHs in control also suggest that root uptake was the main pathway for accumulation of PAHs in this halophytic plant. By this capacity to uptake PAHs from fuel oil contaminated soil, Salicornia fragilis appears as a potential bioindicator of marine pollution by petroleum and may have a role in remediating contaminated soil.

The present study was undertaken to evaluate the efficacy of introduced indigenousbacterial isolates for ex situ bioremediation of fuel oil contaminated soil. For this purposethree hydrocarbon-degrading indigenous bacterial isolates were screened from petroleumoil contaminated soil and repeatedly used for inoculation of fuel oil contaminated soil.The total petroleum hydrocarbons (TPH) content was determined by gravimetric method,Hydrocarbon fractions (alkanes, aromatics, asphaltenes and resins) present in TPH wereobtained by silica gel column chromatography. The study showed that some introducedbacterial isolates effectively adapted to the contaminated soil. The bioaugmentation effectwas calculated to raise the numbers of bacteria by approximately one order of magnitudefrom the indigenous population at the site. Ex situ study showed that the introducedbacterial consortium effectively adapted to the local environment of the soil at thebioremediation site.Our results indicated that disappearance of TPH from inoculated soil samples dependedon the general soil impurity, term of bacterial treatment, level of TPH contamination andindividual microorganism efficacy. With application of bacterial consortium andfertilizers, the TPH level was reduced to 60 - 66% after three months.
