Natural Analysis Gas Composition with the 2261 GPA Methods & GPA 2286
Accurate data composition gas is an important aspect of the oil and gas industry. Through Natural Gas Composition Analysis, the chemical characteristics of natural gas can be known based on the content of both hydrocarbons and nonhydrocarbons contained inside. This information is essential to evaluating the quality of the gas, determining the value of the Taylor, supporting the processing process, as well as fulfilling the need for transactions and distribution of gas.
PT Hidea Core support the need for testing and consulting gas analysis for the Oil & Gas industry. Gas Chromatography (GC) By referring to standard GPA 2261 and GPA 2286. These two methods have a different analysis approach to provide information about the composition of gas as it requires characterization and technical evaluation.
Natural Greatness Gas Composition Analysis for Oil & Gas Industries
For exploration companies, production, processing, or distribution of natural gas, the information of composition is one of the basis of quality control and product characteristic evaluations. Natural Gas Composition Testing provides a number of important benefits, among other things:
- Gas Quality Evaluation
Knowing the composition of the components of hydrocarbons and nonhydrocarbons in natural gas. This data helps evaluate the characteristics and quality of the gas based on the specified specifications. - Calorific Value Determination
Gas composition data can be used as the basis of the count value Taylor (heal value), which is one of the essential parameters in quality assessment and value of natural gas energy. - Custom Transfer & Commercial Transaction
Support the need for gas quality evaluations in commercial transactions, distribution and gas handover between producers, suppliers, and consumers. - Access Optization
Giving composition information that can be used to support the evaluation of production, processing and natural gas processing. - Hydrocarbon Characterization
Identify hydrocarbons from methane to heavier parts of hydrocarbons. This information helps understand the characteristics of the gas and the need for advanced analysis.
Natural Gas Composition Testing Parameters
The Natural Gas Composition Analysis testing uses Chromatography Gas to identify and determine the concentration of the components of natural gas. Analytic results are generally specified in molar percentage units (mole%).
Here's a group of components that are generally analyzed in the testing of natural composition of gas:
| Testing Parameters | Chemical formula | Description |
|---|---|---|
| Methane | ♪ | The main hydrocarbon components that generally have the largest concentration in the natural gas. |
| Ethan. | C | Light hydrocarbon components that contribute to the characteristics of gas energy. |
| Propane | ♪ | The hydrogen carbon component that can be part of the Natural Fraction Gas Liquids. |
| Isobutane | i- C | C4 hydrocarbon components with branching chain structures. |
| Normal butane | n-C | C4 hydrocarbon component with a straight chain structure. |
| isuptane | i- C | C5 hydrocarbon components with branching chain structures. |
| Normal Pentane | n-C | C5 hydrocarbon component with a straight chain structure. |
| Hexanes and Heavier Hydrocarbons | C dhak+ | Heavy groups of hydrocarbon components and can require advanced analysis for more detailed characterization. |
| Nitrogen | N | Non-hydrocarbons components that can affect the characteristics of gas. |
| Carbon Dioxide | CO | Non-hydrocarbons components that need to be noticed in quality evaluations and gas processing. |
Component reported depends on the test method, instrument configuration, and analysis scope used. The next gas composition can be used as a base of physical property and the characteristics of gas energy.
Natural Test Method Gas Composition: GPA 2261 & GPA 2286
The analysis of the natural composition of the gas can be performed using the Chromatography Gas Technique, which is the method of separation and the identification of the gas component based on the characteristic interaction with the chromatography system. In the gas industry, standard GPA 2261 and GPA 2286 are used for analysis needs with scope and different levels of characterization.
1. GPA 2261 - Analysis for Natural Gas and Similar Gaseous Mixtures by Chromatography Gas
GPA 2261 is a method of analyzing natural composition of gas and a mixture of gas that kind of uses chromatography gas. This method was used to determine the components of the gas, including the light hydrocarbons and nonhydrocarbons components according to the scope of the method.
The test results give information about the composition of the gas that can be used for quality evaluations, energy characteristics and natural gas treatment needs.
2. GPA 2286 - Extended Analysis for Natural Gas and Similar Gxtures by Temperature -Programmed Gas Chromatography
GPA 2286 is an extended analysis method using Temperature-Programmed Gas Chromatography. This method provides a more detailed characterization of the hydrocarbon component, especially the fraction of hexanes and heavier components.
Extended analysis is beneficial when it takes a more detailed hydrocarbon composition to support a characteristic evaluation of gas and physical property calculations.
GPA differences 2261 and GPA 2286
| Compliance Aspec | GPA 2261 | GPA 2286 |
|---|---|---|
| Analysis Principle | Chromatography gas | Temperature -Programmed Gas Chromatography |
| Analysis Type | Natural Gas Composition | Extended Natural Gas Composition |
| Focus Testing | Gas component according to method scope | The characterization of the hydrogen component heavier in detail |
| Heavy Hydrocarbons Faction | It can be reported as a group of methods | Giving extended characterization to fraction hexanes and heavier components |
| Usage Destination | Evaluate natural gas composition | Evaluation of gas composition with a need for heavy hydrocarbon characterization that is more detailed |
Method Selection GPA 2261 or GPA 2286 It needs to be adjusted to the type of samples, the purpose of analysis, the need for reporting, and the level of detailed composition required.
Natural Application Scope Space
Test results Natural Gas Composition has an important role in the various activities of oil and gas industries. Gas composition information can be used to support the following needs:
- Natural Gas Production - Evaluate the gas composition from the production well to know the characteristics of hydrocarbons and nonhydrocarbons components.
- Gas Processing Plant - Support the characteristic evaluation of gas feeds and the process of separation of hydrocarbon components.
- Quality Control gas - The gas composition check as part of the quality control and evaluation of the matching specifications.
- Custody Transfer - Provides data composition as a basic computation of gas properties for commercial transactions and handover.
- LNG Industry - Support for the gas characterization used in the process of processing and melting natural gas.
In addition to composition, Chromatography gas results can be used as the basis of other parameters such as Gross Calorific Value, Relative Density, Compression Factor, and Wobbe Index using the appropriate method of calculation. The parameters are not automatically a direct result of the analysis of the composition of the gas.
