2 Method for controlling sand in thermal recovery of oil from tar sands1978-09-19controlling sand; thermal recovery of oil; tar sands oil recovery; tar sands; oil recovery; patent; oil productionA method is disclosed for producing oil from a subterranean reservoir of tar sands as unconsolidated oil bearing sands. The method comprises basically (1) setting a screen in an open hole, the screen being large enough to pass a majority of the formation sand and small enough to retain a packing mat...
3 Explaining the "three inch rule": why model flares don't match full-scale2022It was Pohl and co-workers who discovered the so-called "Three Inch Rule" in their work on flares in the 1980s. They found that model flares with pipe diameter less than three inches do not have the same Combustion Efficiency (CE) and stability behaviour as full-scale flares, at least when wind is n...

7 Attrition and abrasion models for oil shale process modeling1991-10-25As oil shale is processed, line particles, much smaller than the original shale are created. This process is called attrition or more accurately abrasion. In this paper, models of abrasion are presented for oil shale being processed in several unit operations. Two of these unit operations, a fluidiz...
8 Method of recovering viscous petroleum from tar sand1976-11-30Patent; Viscous petroleum recovery; Tar sandsRecovery of viscous petroleum such as from tar sands is assisted using a substantially vertical passage from the earth's surface which penetrates the tar sand and has extending therefrom a lateral hole containing a flow path isolated from the tar sand for circulating a hot fluid to and from the vert...

11 Results of mathematical modeling of an oil shale retort having a fluidized-bed pyrolyzer and a lift-pipe combustor1988-01mathematical modeling; oil shale retort; fluidezed-bed pyrolyzer; lift-pipe combustior; varying key process parametersMany aboveground processes have been proposed for retorting oil shale. The common objective is to heat oil shale particles to 450-600°C to pyrolyze the kerogen in the shale and form oil. Either hot gas or hot solid particles may be used to supply heat to the shale. Hot-solids processes heat the coo...
12 Oil shale quarterly report1990-09-05Aboveground oil shale retorting; Hot-Recycled-Solid; HRS; Pyrolysis; Lawrence Livermore National LaboratoryWe are studying aboveground oil shale retorting and have developed the LLNL Hot-Recycled-Solid (HRS) process as a generic, second-generation, rapid pyrolysis retorting system in which recycled shale is the solid heat carrier. In 1984-87, we operated a 1-tonne-per-day FIRS pilot plant to study retort...
13 Apparatus for separating organic material from particulate tar sands and coal and agglomeration of the particulate residue1976-10-05Patent; Tar sands; Coal; Agglomeration of particle residue; Agglomerating liquid; Immiscible; Varsol; Ball agglomeratesA rotatable drum having an interior which tapers in a horizontal direction has a first port at the smaller end for receiving particulate Tar Sands or coal, and an agglomerating liquid, e.g. water, and a second port at the larger end for receiving an organic material separating liquid, e.g. Varsol, w...
14 Results of mathematical modeling of an oil shale retort having a fluidized-bed pyrolyzer and a lift-pipe combustor1988-10Mathematical modeling; oil shale retort; fluidized-bed pyrolyzer; lift-pipe combustor; computer modelA commercial-size, hot-solids recycle retorting process, consisting of a staged fluidized-bed pyrolyzer and a lift-pipe combustor, was simulated using a previously developed mathematical model. The focus of this work at Lawrence Livermore National Laboratory (LLNL) is to show the effects of varying ...
15 Oil shale retorting processes: A technical overview1984-03The challenge facing the oil shale industry is to devise a simple and efficient retorting process that operates at low cost. This will require a thorough understanding of the important physical and chemical processes that occur during retorting, mathematical modeling to analyze the complex interacti...
16 The extraction of bitumen from western oil sands: Volume 21997-11-26bitumen extraction; western oil sands; oil sands; synthetic fuels; natural bitumen; thermally-coupled fluidized-bed tar sands extraction processIn these days of plentiful fuel supplies, synthetic fuels are not in demand; but with the current rate of consumption of oil the importance of synthetic fuels will only increase. The United States currently imports 50% of its transportation fuel and such a dependence could be potentially dangerous, ...
17 Computational study of the anode baking industrial furnaceTurbulent flow; Eddy dissipation model; Combustion, NOx; Zeldovich mechanismIn the aluminium industry, the Hall-Héroult process is used for smelting of aluminium using carbon electrodes such as anodes. The baking process of anodes is required for their maximum efficiency during this electrolysis process. The anode baking process contributes up to 15% costs in the aluminium...
