Available in PDF, EPUB and Kindle. Book excerpt: Petroleum industries are burdened with the problem of handling large quantities of sludge having properties that depend on the nature of the crude oil, the processing capacity, the down-stream capacities, and the design of effluent treatment plants. Oily sludge is a complex mixture of hydrocarbons, water, metals, and suspended fine solids. This composition makes management of the sludge a complicated and costly undertaking. The objective of this research is to develop a technique that would significantly improve the separation of phases so as to allow for their further reuse. This investigation focused on the application of electrokinetic phenomenon for the remediation of oily sludge. To assess the effect of surfactant on the electrokinetic mobilization of organic contaminants in oily sludge, an amphoteric surfactant was used. Tests were performed in a series of electrokinetic cells with different electrical potentials. During 32 days of the experimental, electrical parameters and pH were measured daily, while samples collected at strategic intervals were analyzed by UV/VIS and FTIR methods. This research lies at the forefront of electrokinetic technology and embraces a combination of several processes including electrocoagulation, electrocoalescence, desorption, electrophoresis, and electroosmosis. The results obtained permit an assessment of the thermodynamics of the proposed process and introduce new theories on the behavior of the colloidal component of oily sludge under different electrical potentials. The results demonstrated an excellent separation of phases; these consisted of water, hydrocarbon, and solid phases. The recovered solid phase exhibited high hydrocarbon content, so it could be reused. The separated liquid hydrocarbon could be reused in other processes. Some volatile hydrocarbons were released during the process. Advantageously, these gaseous hydrocarbons may be captured and burned as fuel. The results showed that the separated water had a low concentration of hydrocarbon, suitable for sending to the wastewater treatment plant. The method allows for the recycling of the hydrocarbon residue of a waste stream into a usable refinery product by achieving a 63% reduction in water content, and, thereby, reduces or eliminates the potential liability for environmental contamination arising from the disposal of waste stream products.

Available in PDF, EPUB and Kindle. Book excerpt: The disposal of the oily wastes represents a serious threat to the environment. The treatment of such oily wastes poses significant challenges considering their physical and chemical properties. This study focuses on advanced electrokinetic methods as a technology to treat oily sediments through phase separation. The study comprises four objectives which are intimately linked to achieve the overall objective of exploring the electrokinetic method for treatment of water-in-oil emulsions. The first objective is finding the most efficient oil phase separation when four different regimes of electric fields are applied (namely constant direct current (CDC), pulsed direct current (PDC), incremental direct current (IDC) and decremental direct current (DDC)). The second objective is to investigate the factors affecting the electrokinetic process and dewaterability of different types of oily sludge. The third objective is investigating the effect of nanoparticles and synthesized catalysts on the phase separation efficiency within the electrokinetic system. The final objective was to elucidate the various mechanisms underlying the separation of oil, water and solids by thermal analysis of treated samples. The results showed that the extent and quality of phase separation depend on the regime of electrical current applied. The DDC and IDC regimes resulted in the most efficient phase separation of the oil sediments, and even incurred a highly resolved separation of light hydrocarbons at the top anode. X-ray photoelectron spectroscopy (XPS) analyses showed a decrease in the concentration of carbon from 99% in centrifuged samples to 63% on the surface of the solids treated by PDC. Wettability alteration studies showed an increase in the level of fine solids in the aqueous phase following electrokinetic treatment thereby enhancing the hydrophilicity of the solids. The best performance of titanium dioxide (TiO2) nanoparticles and a synthesized catalyst reactors results were obtained with the synthesized catalyst as compared to the use of TiO2 nanoparticles. Activation energy emphasized the effect of additives on separation of phases and availability of oil. Hence, the synergistic effects of TiO2 or synthesized catalyst with electrokinetic treatment can lead to better phase separation and may reinforce the current applications of the electrokinetic method in treating oil sediments.

Available in PDF, EPUB and Kindle. Book excerpt: The globally escalating population necessitates production of more goods and services to fulfil the expanding demands of human beings which resulted in urbanization and industrialization. Uncontrolled industrialization caused two major problems – energy crisis and accelerated environmental pollution throughout the world. Presently, there are technologies which have been proposed or shown to tackle both the problems. Researchers continue to seek more cost effective and environmentally beneficial pathways for problem solving. Plant kingdom comprises of species which have the potential to resolve the couple problem of pollution and energy. Plants are considered as a potential feedstock for development of renewable energy through biofuels. Another important aspect of plants is their capacity to sequester carbon dioxide and absorb, degrade, and stabilize environmental pollutants such as heavy metals, poly-aromatic hydrocarbons, poly-aromatic biphenyls, radioactive materials, and other chemicals. Thus, plants may be used to provide renewable energy generation and pollution mitigation. An approach that could amalgamate the two aspects can be achieved through phytoremediation (using plants to clean up polluted soil and water), and subsequent generation of energy from the phyto-remediator plants. This would be a major advance in achieving sustainability that focuses on optimizing ‘people’ (social issues), ‘planet’ (environmental issues), and ‘profit’ (financial issues). The “Phytoremediation-Cellulosic Biofuels” (PCB) process will be socially beneficial through reducing pollution impacts on people, ecologically beneficial through pollution abatement, and economically viable through providing revenue that supplies an energy source that is renewable and also provides less dependence on importing foreign energy (energy-independence). The utilization of green plants for pollution remediation and energy production will also tackle some other important global concerns like global climate change, ocean acidification, and land degradation through carbon sequestration, reduced emissions of other greenhouse gases, restoration of degraded lands and waters, and more. This book addresses the overall potential of major plants that have the potential to fulfil the dual purposes of phytoremediation and energy generation. The non-edible bioenergy plants that are explored for this dual objective include Jatropha curcas, Ricinus communis, Leucaena leucocephalla, Milletia pinnata, Canabis sativa, Azadirachta indica, and Acacia nilotica. The book addresses all possible aspects of phyto-remediaton and energy generation in a holistic way. The contributors are one of most authoritative experts in the field and have covered and compiled the best content most comprehensively. The book is going to be extremely useful for researchers in the area, research students, academicians and also for policy makers for an inclusive understanding and assessment of potential in plant kingdom to solve the dual problem of energy and pollution.
