In this paper an oil-water de-emulsification process within large tanks using ultrasonic technology is presented. As the device would operate in hazardous areas, it should not consume an excessive amount of electrical power. Hence, the paper investigates the suitable oil-water concentrations (10-90% concentrations in step of 10%) which would lead to the fastest separation while consuming the mi...

Global events can trigger new challenges and changes in strategy in the blink of an eye. Knowledge intensive industries require early and accurate notification of global market changes as well as solid information collection strategies which are vital to good decision making. For these purposes, the adoption of semantic technology will make companies aware of changes (ongoing and prospective) a...

Radioactive isotopes were first applied to investigate industrial problems some sixty years ago and since then, there has been a continuous expansion in their usage. The oil industry, in particular, was quick to recognise the potential usefulness of this technology and one of the earliest industrial studies in the literature is concerned with the use of radioactive material to tag the cement of...

In this essay the situation of petroleum knowledge creation and dissemination in Iran oil industry and its technological capabilities have been investigated. This configuration and trend has been studied by a documentary method and content analysis of the scientific articles that published in  a distinguished  journal of Iran oil industry  and so the related structures during  1979-1908.the res...

Solvent extraction, an innovative adaptation of existing crude oil refining technology, is being

In view of disadvantages of commercially available oil level sensing products, this paper introduces a new mechanical type of oil sensor for refrigeration compressor’s oil level protection, which is used to avoid failure due to lack of oil in the compressor, especially when multi-compressors were connected in parallel. The paper analyzed this new mechanical oil senor in terms of superiority com...
