Abstract: Evaluation possibility of a low quality Egyptian oil shale from Wadii El-Nakhil, Red sea region as an alternative clean fuel by flotation technique was investigated. Oil shale sample was characterized using XRD and FTIR analyses to determine its mineral content and surface characteristics. XRD analysis showed that the non-clay minerals present in the oil shale sample include; quartz, siderite, apatite, anhydrite and calcite. The clay mineral is mainly represented by kaolinite while the organic matter is 30%. The effects of frother and collector dosages and pulp Ph on the flotation performance were investigated using kerosene as a collector. The pine oil or MIBC were used as frothing agents. By using 5g/kg kerosene as a collector and 9g/kg of MIBC as a frother at pH 9, a kerogen of 38% with recovery of 88.5% was obtained from oil shale sample of 28%.

Abstract: As a result of experiments it was confirmed the unfolding of molecules under wall-adjacent turbulence conditions, as well as it was proved that dynamic structure formation in polymer solutions is occurred under the influence of supercritical longitudinal gradients of speeds. On the basis of data that characterize macromolecule dynamics in non-turbulence flow with stretching and the proved evidence of strong deformation effect on macromolecules in wall-adjacent turbulence, it has been established the molecular-and-supermolecular mechanism of effect reduction for flow resistance when injecting soluble polymer additives in a turbulence flow. Understanding the mechanism of reducing drag flow of oil in pipelines by small polymer additions will allow to develop recommendations on the choice of rational hydraulic regimes oil pipelines, as well as to outline ways for the directed synthesis of high-performance polymer additions that reduce friction in the turbulent oil pipelines.
