Petroleum products, such as gasoline, leaked from an underground storage tank can be recovered successfully by two-pump operations. The success of the recovery effort depends on the accurate placement of the recovery well at the spill site. An effective recovery operation can minimize the remaining contamination mass in the subsurface. Therefore, a careful evaluation and determination has to be made as to where to locate the recovery well. The location of the well can be decided based on an estimation of the extent and thickness of free product on the water table. Such an estimation should be based on analysis of governing mechanisms. In this study we present analytical solutions to estimate the recovery of oil from an established oil lens. These solutions are obtained by applying the Laplace transformation to averaged linear partial differential equations governing the phenomenon. The governing equation for the free product thickness is derived by averaging the oil phase mass balance equation along the free product thickness and substituting the boundary conditions at the oil/water interface and oil surface. The analytical solutions estimate the temporal and spatial distribution of free product thickness on the water table for a number of recovery scenarios. Results are presented for the temporal and spatial variation of the free product thickness, temporal variation of the free product Volume recovered, and recovery efficiency based on the readings at the monitoring wells. Since they can be utilized without a great deal of data, analytical solutions are quite attractive as screening tools in two-pump free product recovery operations.

A SEMIANALYTICAL ANALYSIS OF COMPRESSIBLE ELECTROPHORETIC CAKE FORMATION KAMBHAM, KKR; Tuncay, Kağan; CORAPCIOGLU, MY (American Geophysical Union (AGU), 1995-05-01) Leaks in geomembrane liners of waste landfills and liquid impoundments cause chemical contaminants to leak into the subsurface environment. A mathematical model is presented to simulate electrophoretic sealing of impoundment leaks. The model describes the formation of a compressible clay cake because of electrical and gravitational forces. The model includes mass balance equations for the solid-particles and liquid phase, modified Darcy's law in an electrical field, and Terzaghi's definition of effective st...
Nickel sorption by acclimatized activated sludge culture Arican, B; Yetiş, Ülkü (Elsevier BV, 2003-08-01) The sorption of Ni2+ by acclimatized activated sludge treating Ni2+ bearing wastewater was investigated using a once-through completely mixed tank reactor. The culture developed from sewage was acclimatized to 85.2 mumole/L Ni2+ influent concentration by stepwise increases, at a low dilution rate 0.11/h. Acclimation was found to enhance the sorptive capacity of the activated sludge. In fact, at all of the intermediate concentrations, percentage Ni2+ adsorbed by the biomass and also the sorptive capacity of ...
Performance prediction of underground gas storage in salt caverns Bagci, A. Suat; Ozturk, E. (Informa UK Limited, 2007-01-01) Underground gas storage is a common activity in countries with major transport and distribution gas pipeline infrastructures, which allows to efficiently resolve demand seasonality problems. Subsurface caverns in salt formations are being increasingly used for storage of natural gas. In this study, a real salt cavern having the potential for being an underground gas storage unit was evaluated. A model of the salt cavern was constructed within the gas simulator established for the purposes of this study. The...
Screening and In Situ Monitoring of Potential Petroleum Hydrocarbon Degraders in Contaminated Surface Water İçgen, Bülent (Wiley, 2017-01-01) Incomplete combustion of fossil fuels and other anthropogenic activities result in contamination of surface water by petroleum hydrocarbons. These pollutants can have severe effects on aquatic life and human health. In petroleum bioremediation, oil degrading microorganisms are utilized to remove petroleum hydrocarbons from polluted water. However, monitoring and identifying microorganisms capable of degrading petroleum hydrocarbons is very challenging. In the current study, bacteria isolated from a river al...
Estimation of river flow by artificial neural networks and identification of input vectors susceptible to producing unreliable flow estimates Kentel Erdoğan, Elçin (Elsevier BV, 2009-09-15) Reliable river flow estimates are crucial for appropriate water resources planning and management. River flow forecasting can be conducted by conceptual or physical models, or data-driven black box models. Development of physically-based models requires an understanding of ail the physical processes which impact a natural process and the interactions among them. Since identification of the relationships among these physical processes is very difficult, data-driven approaches have recently been utilized in h...
