The Chemistry of Shale Oil and Its Refining

Mid-chain carboxylic acids by catalytic refining of microalgae oil

Microalgae oil serves as a feedstock for a biorefinery approach to mid-chain (di-)carboxylic acid esters, currently only accessible via demanding synthetic routes. Via the butenolysis of monoand poly-unsaturated fatty acids, short-chain unsaturated fatty acid methyl esters and monoand di-enes were produced in a high selectivity. These olefins were further processed into value added linear mid-c...

Procurement planning in oil refining industries considering blending operations

This paper addresses procurement planning in oil refining, which has until now only had limited attention in the literature. We introduce a mixed integer nonlinear programming (MINLP) model and develop a novel two-stage solution approach, which aims at computational efficiency while addressing the problems due to discrepancies between a non-linear and a linearized formulation. The proposed mode...

Investigation of Oil inside the Wells in REY Area in Tehran Oil Refining Company in Iran

REY area has been located in Tehran Province and several archaeological ruins of this area indicate that the settlement in this area has been started since several thousand years ago. In this paper, the main investigation items consist of analysis of oil components and groundwater quality inside the wells. By finding the contents of oil in the well, it is possible to find out the pollution sour...

Comparative Study between Physical Properties of Virgin Oil and Re-Refining Oil

The lubricating oils are essential for operating engine with high efficiency. Therefore, the physical properties of oil such as flash point, pour point, kinematic viscosity, specific gravity and the American Petroleum Institute are necessary to be studied to indicate good quality of the lubricating oil. In this study, we compare the physical properties of two virgin oils with re-refining oil. T...
