Benzena Analysis, Toluena and Xilena (BTX) by Chromatography Gas
The characterization of aromatic hydrocarbon compounds is one of the most important aspects of petroleum quality control and petrochemical industry. Benzene, Toluena, and Xilena (BTX) are aromatic compounds that are widely used as raw materials and components in various industrial processes. Analysis of these three compounds is required to know the composition and concentration of each component in a sample.
PT Hidea Core supports laboratory analysis needs for the characterization of petroleum products and hydrocarbon compounds through the approach of chromatography analysis. The test by BTX gas chromatography allows separation and determination of Benzena, Toluena, as well as Xilena based on the characteristics of the chromatography of each compound. Analysis can be used as support data in product quality evaluations, process control, as well as the need for raw materials and industrial products.
BTX Analysis for Oil & Gas Industry
For the Oil & Gas sector, petrochemical, and the hydrocarbon processing industry, information about the aromatic compound composition is an important part of the product characterization process. The BTX Analysis tests provide quantifiable information about the content of Benzene, Toluena and Xilena so that the chemical characteristics of the sample can be evaluated more accurately.
Some of the major benefits of BTX testing include:
- Aromatic Hydrocarbon Component Identification
BTX analysis is used to identify and determine the concentration of Benzene, Toluena, as well as Xilena in samples based on the separation of chromatography. - Petroleum Proposition Composition Evaluation
The content data of aromatic compounds can be used as part of the characterization and quality control of the petroleum products and the raw materials of the petrochemical industry. - Monitoring Default and Product Quality
The test results help provide information about the aromatic compound composition that can be used to support the consistency evaluation of raw materials and products during the industrial process. - Industrial Process Control Support
BTX concentration information can be a support data in evaluation of hydrocarbon processing processes, monitoring product composition, and quality control needs.
Benzena Testing Parameters Specification, Toluena, and Xilena (BTX)
The BTX testing was done to determine the nature of three major aromatic compounds, Benzena, Toluena, and Xilena. Each component has a characteristic of chemistry and a time of different chromatography so it can be analyzed through separation using Chromatography Gas.
Here are the main parameters in the BTX testing:
| Testing Parameters | Specification |
|---|---|
| Benzene | Determines benzene concentration in samples |
| Toluene (C DESH) | Determines the toluena concentration in the sample |
| Xylene | Determines the concentration of xilena in samples |
| Analysis Method | Gas Chromatography (GC) |
| Analysis Principle | Separating components based on interaction with motion phases |
| Testing Results | Concentrate each component on the method and calibration used |
On analysis that requires isomer xilena identification separately, parameters can be narrowed down to:
- Ortho-Xylene (o-Xylene)
- Meta-Xylene (m-Xylene)
- Para-Xylene (p-Xylene)
The separation of each isomer depends on setting the column and operational conditions of the used Chromatography Gas.
BTX Analysis Method Using Chromatography Gas
Gas Chromatography (GC) It's an analysis technique used to separate and determine the components of the volatile compound in a sample. In BTX testing, each of these compounds are separated based on the difference in their interaction with the silent phase of the chromatography and its volatile characteristics.
In general, the principle of BTX analysis uses Chromatography Gas includes the following stages:
- Sample Preparation - Samples prepared according to the characteristic matrix and need for testing methods.
- Sample Injection - The sample is inserted into the GC injection system to the next carried by gas carrier to the chromatography column.
- Separation Process - Benzene components, Toluena, and Xilena are splitting in columns based on interaction with silent phases and analysis conditions.
- Component Detect - Separate packages are detected using detectors that correspond to instrument settings, such as Flame Ionization Detectors (FID) or Mass Spectrometer (MS).
- Identification and Kuanification - Identification is based on characteristic chromatography and standard of comparison, while the concentration of components is determined by the calibration procedure used.
The selection of types of detectors, columns, and operational conditions needs to be adjusted to the type of samples and purpose of analysis. At BTX testing, the separation of the xilena component also needs to be noticed if analysis requires a determination of concentration of each isomer separately.
BTX and BTEX differences in Aromatic Hydrocarbons Analysis
In aromatic hydrocarbons characterization, the term BTX and BTEX are often used to describe analyzed compound groups. Both have differences in the number of components that are included in the testing scope.
- BTX (Benzene, Toluene, Xylene)
It covers three major aromatic compounds, which are Benzene, Toluena, and Xilena. - BTEX (Benzene, Toluene, Ethylbenzene, Xylene)
It covers Benzena, Toluena, Etilbenzena, and Xilena. Thus, BTEX has an additional component of analysis, which is Etilbenzena.
The scope difference is important to note when determining testing parameters. The BTX or BTEX selection needs to be adjusted to the need for sample characterization and the desired analysis specifications.
