simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Study of the Mechanism and Causes of Pore Formation in Sr-modified Al-Si Alloys
The formation of microporosity in modified Al-Si alloys has been reviewed in the present study. A major concern in modification is the increased tendency to form microporosity in the macro-shrinkage free Al-Si alloy castings. It has also been demonstrated that at low hydrogen contents (0.1cc/ 100g, Al), where only shrinkage porosity should occur, the effect of Sr-modification on porosity conten...

متن کاملPore Formation Process of Porous Ti3SiC2 Fabricated by Reactive Sintering
Porous Ti3SiC2 was fabricated with high purity, 99.4 vol %, through reactive sintering of titanium hydride (TiH2), silicon (Si) and graphite (C) elemental powders. The reaction procedures and the pore structure evolution during the sintering process were systematically studied by X-ray diffraction (XRD) and scanning electron microscope (SEM). Our results show that the formation of Ti3SiC2 from ...
متن کاملPore Formation Mechanism of Staphylococcal Pore- forming Toxin
Y. Tanaka and M. Yao (Hokkaido Univ.) Pathogenic bacteria express pore-forming toxins (PFTs) to attack host cells. PFTs are expressed as soluble monomeric proteins, which assemble to prepore oligomer on the target cells. After forming prepore, conformational change occurs, and then the pore is formed. Although the crystal structures of monomer and pore have been determined, the detailed mechani...
