Analysis for oil shales has been one of the major environmental issues these days. It is necessary to analyze oil shales before any oil refining or drilling is done. Analysis for oil shales comprises of both analytical techniques and geochemical techniques. Both of these techniques can be utilized for obtaining valuable data about oil and its alloys.
There are several techniques of chemical analysis for oil shales and retorts. These techniques are designed in such a way to support the industrial field testing of the different pollution controlling systems. Analytical techniques used for analyzing for oil shall consist of solvent extraction, gas sampling, chemical adsorption, infrared spectroscopy, and electromagnetic co-relation. Some other important techniques for analysis for oil shales are sedimentation analysis, water sampling, and mineral composition modeling.
Oil solvent extraction is the first method utilized in analysis for oil shales. This method is used to derive oil particles in heavy salts from the reservoir. The oil-solvent extraction method can be efficiently run on methanol. This method is mostly utilized for analyzing oil shales at low temperatures. In the high temperature scenario, benzene ring formation is another unwanted effect.
Gas sampling is also a good method to analyze for oil shales. The sample is laid on the platform of a drilling vessel which is placed inside a well. The sample is then pumped into a vat of water, where a sample of oil will stick to the surface of the water. The benzene concentration in the sample will be determined using a gas chromatography method.
An analysis for oil shale cannot be complete without the use of infrared spectrophotometry. In this method, an infrared light is provided on the oily sample. The oil droplets pass through the droplets and return as infrared rays. The amount of the infrared rays that pass through the sample will determine the content of the oil droplets. This analysis for oil shales is quite efficient in determining the percentage of the benzene group in the crude oil.
All the above mentioned methodologies are extensively used in the petroleum industry. They are mainly applicable in cases where qualitative analysis is required. They are generally used for analysis of petroleum fluids with high temperatures.
These methodologies are also adopted for the separation of solvents from liquids. Steam distillation is also one of them. They are mainly adopted by chemists as it is an economical method. There are many advantages of using these methods. These include economical process, quickness of analysis and simplicity.
There are some drawbacks of these methodologies as well. It may take several days to conclude the result. This may be because of unavailability of the required material. It may also be because of low quality of the material being used. Some of the methodologies also involves some complex process. The accuracy of results may also not be guaranteed.
In spite of these drawbacks, it can be said that these methodologies have been widely used across the world. Some of the better known methodologies include turbidity analysis, sedimentation analysis, Tera-foliation and organic solvent extraction. In the case of turbidity analysis, it is important to use accurate equipments and proper materials. The sedimentation methodologies demand for high temperatures. Organic solvent extraction is also a method used for analytical purposes in the petroleum industry.
The analysis for oil shales is very sensitive and requires accurate observations. The observations should be performed in various temperature settings. The observations should be performed on samples of the substance being tested. If the sample is not mobile then there will be no data to analyze. Analysis for oil shales can be done through many of the known analytical methods including spectrometry, gas Chromatography, Infrared Spectroscopy and Mass Spectrometry.
There are many companies which have developed advanced methodologies. These methodologies are used in various applications across the globe. It is therefore important to choose the company that can provide you with a wide range of services. A company can help to conduct the test and can perform all the test on your behalf. Some of these companies even offer consultancy services apart from the test and analysis for oil shales. The consultancy services are usually provided on a cost-per-project basis.
Analysis for Oil Shales is an integral part of chromatography and related technology. It is therefore important to choose the right methodologies. It is also very important to select methodologies which can be implemented at the site of processing. This will help in reducing cycle times. When the cycle time of the process is reduced the productivity will increase.
