Monitoring Oil Content In the Produced Water From the Usinsk Oil Field By IR-spectroscopic Methods

According to the problem of polymeric compound appearing in oil field produced water, following by the changes of water quality characteristics that result in the polymeric compound accumulated in the filter tank which lead to the poor regeneration, being partly hardened and the losing, and the over standard of water quality, the study uses the technology of axial dynamic backwashing to back wash and regenerate the dual-media filter of walnut shell/quartz sand. The removal rate of oil content for filter materials reaches above 90% after backwashing. Simultaneously, cleaning the granular filter materials in filter bed achieves high removal rate of oil and suspended substance content, the average removal rate of oil content being 96.0% while the suspended substance 77.81% which greatly improved the water quality index.

Abstract Background Environment-friendly fast and accurate mid-infrared spectroscopic methods have been developed for the quantitative analysis of doxorubicin hydrochloride (DOX) and arterolane maleate (ALM) in bulk and marketed formulations. Both transmittance and reflectance modes have been used for the analysis and a comparison has been drawn for better accuracy. The analytical methods were validated in accordance with International Council for Harmonisation (ICH) guidelines Results The proposed methods have been successfully developed and validated for the quantification of doxorubicin and arterolane maleate in solid bulk and dosage form. High recovery values in both the modes, while analysing DOX and ALM, indicated good accuracy of the methods. The methods showed excellent repeatability and intermediate precision [% RSD (Relative Standard Deviation < 2.0%]. The assay values of the drugs in solid dosage forms were also found close to the labelled claim. Conclusion The proposed Fourier transform infrared (FT-IR) spectroscopic methods were found to be specific, reproducible, valid and could be used as general methods for the quantification of most of the solid drug preparations such as tablets, capsules and powders.

Abstract Oil and gas sectors generate large amounts of oily wastewater, which is called produced water. In which, it contains high concentrations of hazardous organic and inorganic pollutants. This paper attempts to evaluate the performance and quality of using a polyethersulfone ultrafiltration membrane (UFM) to treat the produced water of Al-Ahdab oil field (Wassit, Iraq). 8 rectangular flat sheets of polyethersulfone ultrafiltration membrane were used. The area of each is 60 cm2 and pore size about 15 nm used in the experimental work. Prepared UFM is characterized by determining the surface morphology by scanning electron microscopy (SEM). The result showed that the UFM indicated high removal efficiency in all parameters and especially oil and grease and total suspended solid but in general it still less than the requirement of water reuse. The results showed that, a combination of a conventional treatment method and UFM technology have higher efficiency than using UFM only.
