Transporting crude oil inside a pipeline is a common process in the petroleum industry. Crude oil from different sources has different properties due to terrains and climates which cause the transport profile to change during operations. In this study, the computational fluid dynamics model was developed using computer language code. The governing equations were employed to study the effect of ...

While there is good reason to expect crude oil production to be non-linear, previous studies that have examined the stochastic properties of crude oil production have assumed that crude oil production follows a linear process. If crude oil production is a non-linear process, conventional unit root tests, which assume linear and systematic adjustment, could interpret departure from linearity as ...

Environmental contamination by petroleum hydrocarbons, mainly crude oil waste from refineries, is becoming prevalent worldwide. This study investigates the bioremediation of water contaminated with crude oil waste. Bacillus salamalaya 139SI, a bacterium isolated from a private farm soil in the Kuala Selangor in Malaysia, was found to be a potential degrader of crude oil waste. When a microbial ...

impact of supply chain drivers on supply chain performance has no far been studied. in this research we want identifying supply chain drivers, classifying them and examining their relationship with iran's supply chain performance. this research has innovation in identifying and classifying drivers and examining relationship between drivers and supply chain performance we used bsc for assessing ...

an isolate from polluted soil identified as aspergillus sp. ms-100 was able to consume vanadium oxide octaethyl porphyrin as a model for protoporphyrins in crude oil. the isolate degrades about 55% of vanadium oxide octaethyl porphyrin (vooep) under optimum conditions during 7 days. the release of more than 0.96 mgl-1 of free vanadium into the aqueous phase was confirmed using atomic absorption...

Crude oil is one of the most important energetic resources in the world. It is used as raw material in numerous industries, including the refinery-petrochemical industry, where crude oil is refined through various technological processes into consumer products such as gasoline, oils, paraffin oils, lubricants, asphalt, domestic fuel oil, vaseline, and polymers. Oil-derived products are also com...

The chemical and physical characteristics of Malaysian palm kernel and its products are discussed in this article. The main products derived from palm kernel are palm kernel oil, palm kernel olein and palm kernel stearin whereas the by-products are palm kernel meal and palm kernel fatty acid distillate. The major composition of the kernel is oil (49%), followed by carbohydrate (26.1%), protein ...
