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...

Buried or inaccessible piping systems within Nuclear Power plants present a challenge in terms of overall inspection. Limited access and complex piping configurations restrict the type of indirect or direct NDE methodologies which can be applied by inspectors. Due to the complexity of buried and above-grade piping systems routed in and around these facilities, many plants have been forced to lo...

in this paper the issue of evaluating iranian oil refineries performance has been discussed. the research is based on math modelling by operational research techniques. to do so, of the proposed scenarios and different math programming models, a model is made by combining dea with goal programming techniques that compared with the old classical dea models which measures the efficiency and produ...

Organizations that implement strategic energy management programs have the potential to achieve sustained energy savings if the programs are carried out properly. A key opportunity for achieving energy savings that plant managers can take is to determine an appropriate level of energy performance by comparing their plant’s performance with that of similar plants in the same industry. Manufactur...
