Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of a Danish waste refinery solution against state-of-the-art waste technology alternatives (incinerat...

Hydrodistilled volatile oils, as well as the extracts from waste water after hydrodistillation from the aerial parts of Satureja montana and Satureja cuneifolia, growing wild at Mt. Biokovo (Croatia), were analyzed by GC-MS. Sixty compounds were identified in four samples. The major constituents of essential oil obtained from the plant material of S. montana were carvacrol (63.4%) and thymol (1...

Moringa oleifera seeds contain about 40% of highly valued oil due to its wide range of applications, from nutritional issues to cosmetics or biodiesel production. The extraction of Moringa oil generates a waste (65%-75% of seeds weight) which contains a water soluble protein able to be used either in drinking water clarification or wastewater treatment. In this paper, the waste of Moringa oleif...

A unique membrane filtration system has been installed at several major waste oil hauling operations and manufacturing plants that handle or produce oily wastewater. The system manufactured by New Logic, of Emeryville California near San Francisco, is also being used to process used crankcase waste oil and produce filtrate that can be sold as a higher value bunker oil. The V✧SEP, (Vibratory She...

This paper presents an integrated refinery scheduling model and its applications for a refinery located in Jiujiang, Jiangxi, P.R.China. The model integrates a crude oil unloading and storage area, a refining area, a blending area and a product storage area of the refinery. The scheduling model can be applied for optimizing the operation, configuration and production schedule of the refinery. T...

background and objective: prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. the purpose of this study was to compare the etba and hazop techniques for risk assessment in a gasoline refinery unit. methods: in this case study, data were collected using process flow diagram, walking–talking through method, piping a...

The energy industry and in particular the Oil Refineries are extremely important elements in Iraq’s infrastructure. A terrorist attack on one oil refinery will have a catastrophic impact on oil production and the whole economy. It can also cause serious damage to the environment and even losses of human lives. The security of information systems and industrial control systems such as Supervisor...

Edible fats and oils are produced by three main industries: oil, margarine and rendering. As margarine manufacture requires only substances that have already undergone refining, the only waste water comes from rinsing the equipment and premises. The oil industry with its different phases of refining uses large quantities of water but could cut its consumption by a more rational organization of ...

Abstract In the given work one can learn about methods for obtaining fuel briquettes from hydrocarbon-containing wastes of oil refineries as a binder are considered, and comparative analysis performance characteristics obtained products previously known is carried out. To improve properties sludge briquettes, study being out and, first time, it recommended to use licorice root production waste ...
