Raw oil composition characterization (code oilIt's one of the most important aspects of the Oil & Gas industry.
Through SARA Analysis, according to four major factions. This test uses the principle of separation based on polarity differences and the unified characteristics of components, one of which through the Liquid Chromatography technique.
As a company that moves in the field Oil & Gas Laboratory Testing Services, PT Hidea Core supports the need for testing and the characterization of petroleum through technical consulting labs. SARA analysis services need for oil crudes can be consulted to determine the alignment of parameters, testing methods, and analysis needs based on the characteristics of samples.
SARA Analysis for Oil Industries & Gas
For oil and gas companies, understanding the composition of the oil cruil became an important part of technical and operational decision-making. SARA Analysis gives information about the distribution of hydrocarbons that can be used for various industrial needs, among other things:
- Crude Oil Characterization
Knowing the distribution of the crude oil composition based on the fraction of the saturates, the aromacs, the Resins, and Asphaltens as part of a statistical evaluation of crude oil. - Asphaltene Stability Evaluation
Supports the characteristic evaluation of asphaltene related to the potential of precipitation and deposit establishment during production and oil processing. - Crude Oil Blending Compatibility
Provides support data to evaluate the compatibility of some kind of oil crude before the mixing process (blending). - Feedstock Evaluation Resfinery
Giving information on the composition of raw oil fractions that can be used as one of the considerations in the raw materials evaluation process refinery. - Flow Assurance
Supporting the investigation of the characteristic of oil that is potentially related to the issue of deposit and the impediment of flow in the production and transportation system.
Test Parameters Specification SARA Analysis
The test of SARA Analysis was intended to determine the percentage of four major factions in the oil crude. Each faction has a different chemical characteristic and provides its own information about the composition of the sample.
| No. | Testing Parameters | Analysis Description | Units |
|---|---|---|---|
| 1 | Saturates | Hydrocarbon fractions are saturated, including paraffin and cycloparafin. | % |
| 2 | Arotics | Aromatic hydrocarbon fractions | % |
| 3 | Resins | The fraction of resin compounds that have more polar characteristics | % |
| 4 | Asphaltens | Asphaltene fractions based on the characteristic of decomposition and separation. | % |
| 5 | Total SARA | The total number of fraction of saturates, roostics, Resins, and Asphaltens | % |
Test results are generally presented in heavy percentage (weight percent or wt.%), depends on the method used. The total fraction of SARA can be used as a consistency examination of the mass balance results.
SARA Analysis Method using Liquid Chromatography
Liquid Chromatography It's a separation technique that utilizes interaction between the components of the sample, a silent phase (station phase), and motion phase (mobile phase). These interactions allow components in a crude oil separated into factions based on its chemical characteristics.
In stera testing, the separation process can involve the use of adsorben materials, chromatography columns, as well as certain solvent procedures of the method being used.
Some of the methods and technical references related to the SARA testing include:
- ASTM D2007 - The method for determining hydrocarbon groups in petroleum oils through clay--gel adaption chromatography techniques.
- IP 469 - The testing method for the decisive fraction of the saturates, the aroutics, the Resins, and the Asphaltens on the petroleum products.
The method selection should consider the type of samples, the characteristics of the oil crude, the purpose of testing, as well as the adjustment of analysis procedures. Those methods should not be considered identical because the principles and scope of applications can be different.
It was SARA Analysis in the characterization of Crude Oil.
Results data SARA Analysis It gives a deeper picture of the characteristics of crude oil. This information becomes relevant in some industrial technical need:
- Hydrocarbon Composition Evaluation - It helps understand the distribution of major fractions in the oil crudes.
- Asphaltene characteristic identifier - It became a supporting data to evaluate the behavior of the asphaltene fractions in the petroleum system.
- Crude Oil Blending Evaluation - Support mixed compatibility studies for some kind of crude oil.
- Optimize Processing - Giving extra information to understand the feedstock characteristics that will be processed in refinery.
- Petroleum Studies and Research - Provides characterization data for technical study needs, process development, and oil quality evaluations.
It is important to note that the results of SARA Analysis are not the only basis to conclude the stability of the oil crude or the potential for deposit formation. Interpretation should be carried out with other testing parameters and relevant operational conditions.
Consult the needs of the S.H.R. Analysis Services for Crude Oil
The selection of methods and the proper testing parameters is an important step towards getting the lab data that suits the industry. PT Hidea Core provides lab testing services in Oil & Gas, including technical consulting support for petroleum characterization and cruise oil.
