consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
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. ...
Extremophiles in Mineral Sulphide Heaps: Some Bacterial Responses to Variable Temperature, Acidity and Solution Composition
In heap bioleaching, acidophilic extremophiles contribute to enhanced metal extraction from mineral sulphides through the oxidation of Fe(II) and/or reduced inorganic sulphur compounds (RISC), such as elemental sulphur or mineral sulphides, or the degradation of organic compounds derived from the ore, biota or reagents used during mineral processing. The impacts of variable solution acidity and...
متن کاملEPR and optical absorption spectral studies on sphalerite mineral.
The mineral sphalerite (Zn,Fe)S has been characterized by a combination of X-ray diffraction, EPR and NIR spectroscopy. The optical absorption spectrum of mineral sphalerite is due to an iron impurity only, which is in a distorted octahedral environment. The g=2.2 is attributed to iron and g and A value observed in the spectrum 1.999 and 6.0 mT are assigned to Mn(II) impurity in the mineral. Th...
متن کاملEffect of zinc and boron interaction on growth and mineral composition of lemon seedlings in a calcareous soil
The impact of different concentration of zinc (Zn) and boron (B) on growth and mineral composition of lemon seedlings (Citrus Aurantifolia L.) was studied under greenhouse conditions. We used five concentration levels of B (0, 2.5, 5, 10 and 20 μg g-1 soil) and three of Zn (0, 5 and 10 μg g-1 soil). Fresh and dry plant weights of the control treatment were strongly decreased with B levels highe...
