Water flooding microscopic seepage experiment is an effective method to study the microvadose mechanisms as well as the distributions of remaining oil. Throughout the experiment the quantitative description of the porous medium fluid flow parameters such as porosity, oil saturation and so forth is crucial. A quantitative analysis method is proposed via image processing, including image preproce...

Ultrasonic extraction of kerogen derived by acid treatment of Huadian oil shale is performed using an organic solvent. The most effective solvent is the 60:40 (wt%) mixture of chloroform and carbon disulfide, and the suitable mass ratio of the demineralized oil shale to solvent is 1:20. The oil yield by ultrasonic extraction can reach 15.6% based on the demineralized oil shale, compared with a ...

In Malaysia, most of the PKC produced are from expeller extraction. Though solvent extraction is also used in the extraction of palm kernel oil but the process is costly and screw press extraction (expeller) is the rule in many palm oil processing plants. The difference in the quality of expeller PKC and solvent extracted is small, although in general expeller PKC contains more oil (4%-8%) than...

The oil and gas industry is a data-driven business. The industry depends on information technology (IT) to increase the speed of finding oil, enhance oil production, and reduce health, safety, and environment risks that come with equipment failure or operator error. Processing large volumes of data for reservoir modeling or simulation is not new. What has changed is the availability of new tech...

In view of the fact that oil spill remote sensing could only generate the oil slick information at a specific time and that traditional oil spill simulation models were not designed to deal with dynamic conditions, a dynamic data-driven application system (DDDAS) was introduced. The DDDAS entails both the ability to incorporate additional data into an executing application and, in reverse, the ...

There has been a recent resurgent interest in microalgae as an oil producer for biofuel applications. An adequate supply of nutrients and carbon dioxide enables algae to successfully transform light energy of the sun into energy rich chemical compounds through photosynthesis. A strain with high lipids, successfully grown and harvested, could provide oil for most of our process by volume, which ...

Storage at 3 and 18 °C of 'Arbequina' olives (Olea europaea L.) cultivated in hedgerows and harvested manually or mechanically (wine grape harvester) was tested. Fruit characteristics and oil quality were monitored. Mechanical harvesting caused internal fruit damage that induced its rapid softening and decay, but also facilitated obtaining higher amounts of oil, which suffered a rapid deteriora...

As studies continue to examine new value added uses for ethanol coproducts, it is important to have means to easily determine the feasibility of the processing steps involved. Many industries widely use computer simulation programs for this purpose, and for planning the use of resources and equipment capacities, and to determine processing costs. The objective of this project was to determine t...

The world productions of olive oil reach 2,800,000 ton and 98% of this production is to be found in the Mediterranean basin, where this agricultural system has been developed for thousands of years, characterized by its adaptation to the environment and its empiricism. Several factors have modified the olive production and processing systems in the last decades. The crisis of traditional agricu...
