Analysis and Testing LNG: Testing Parameters and Utility for Oil & Gas Industries · Global Voices
The Liquefied Natural Gas quality is an important aspect of production, storage, transportation, and liquid natural gas trade. To ensure the characteristics of the product correspond with operational needs and contract specs, it takes analysis and testing of the right LNG based on the type of samples as well as the purpose of testing.
PT Hidea Core (hidea.id) focuses on service labs Oil & Gas to support the needs of analysis and hydrocarbon characterization. The LNG test can include the composition analysis, the Taylor value evaluation, as well as certain quality parameters check for customer needs and available technical scope.
Through LNG Analysis and Testing, lab data can be used to help evaluate product quality, energy calculations, contaminant control, as well as need custom transfer In the LNG supply chain.
Analysis Extitude and LNG Testing for Industrial
For energy companies, gas producers, facility operators, as well as LNG dealers, reliable test data helps support technical and commercial decision making. LNG analysis has some major benefits:
- LNG Composition characterization
The composition analysis gives information about the content of hydrocarbons, such as methane, ethane, propane and butane, as well as other components that can be analyzed by the method. - Evaluate Curor and Energy Values
Composition data can be used to calculate Gross Heating Value (GHV) And Net Heating Value (NHV) Based on the appropriate method of calculation. This information is essential in energy quality evaluation and LNG transactions. - Contaminan Control
Testing certain parameters, such as sulfur compound, carbon dioxide, water, and mercury, can help evaluate the quality of the product and conformity with the terms of the process or the contract. - Support Custody Transfer
The data of composition and energy calculations is an important part of the LNG transfer process, especially when quantity and content becomes the basis of the transaction. - Support Operational Efficiency
Analysis can be used with other data processes to evaluate LNG quality, monitor product consistency, and support the control of production.
ASTM D7940 explains that the determination of the LNG composition can be used to calculate the Taylor value, supporting custom transfer, as well as helping preserve product quality and production efficiency.
Analysis Data Spreadsheet and LNG Testing
As a picture of the testing scope, here are several parameters that can be considered in the LNG Quality Testing program. The selection of parameters, methods and format reports must be adjusted to the characteristics of samples and needs of customers.
| Analysis Parameters | Method / Race Technique | Provided Information |
|---|---|---|
| LNG Composition | Appropriate composition analysis method | LNG component distribution |
| Methane. | According to the method of composition | Methane content |
| Ethane (C DESH) | According to the method of composition | Ethanan database |
| Propane | According to the method of composition | Propane content |
| Butanes (C) | According to the method of composition | Butana content |
| Nitrogen (N spans) | According to the method of composition | nitrogen content |
| Carbon Dioxide. | According to the appropriate method | The content of carbon dioxide |
| Gross Heating Value (GHV) | Calculate based on appropriate composition and method | Bruto Taylor Value |
| Net Heating Value (NHV) | Calculate based on appropriate composition and method | Neto Taylor Value |
| Sulfur Compound | Methods correspond to compounds and range measurements | The content of the sulfur compound |
| Mercury (Hg) | The appropriate method for sample matrix | Mercury content |
Technical notes: That table is an relevant parameter for the LNG testing program, not confirmation that all parameters are available in HIDEA services. Methods like ASTM D1945 used to analyze the natural composition of gas in the gas phase, while ASTM D7940 discussed analysis of LNG using fiber@@. The method selection must follow the type of samples and the need for testing.
Analysis Scope Room and LNG Testing
LNG analysis can be adjusted to the purpose of testing, from composition characterization to product quality evaluation.
- LNG Composition Analysis - Determines the composition of hydrocarbons and other components that include the scope of the analysis method.
- Heating Value Analysis - Using composition data to calculate gross and neto Taylor values based on the appropriate method of calculation.
- Impurity Analysis - Evaluate certain contaminants, such as sulfur compound, CO, water, or mercury, if relevant to product specs and process needs.
- LNG Quality Event - Compare the results of analysis with technical specs, customer requirements, or valid terms of contract.
- Custom Transfer Support - Support LNG handover processes through data composition and energy used in transaction calculations according to related procedures.
Chromatography gas for LNG Composition Analysis
Gas Chromatography (GC) It's an analytical technique used to separate and measure components in the mix of gas. This technique is widely used in the analysis of natural composition of gas and can be part of a gas characterization program relevant to the LNG supply chain.
In general, the composition analysis process with GC covers:
- Sample Handling - Make sure the sample is handled according to procedure and conditions required.
- Sample Interduction - Put samples into the analysis system using appropriate procedures.
- Compound Separation - Separating components based on the characteristics of the chromatography.
- Detections and Punctuation - Detecting and determining components according to instrument and method configuration.
- Processing Data - Product results into composition data, generally in mole or mole unit%.
- Energy Calculation - Using composition as a count input value Taylor and other properties if necessary.
The method selection needs to consider whether the samples analyzed are natural gases in the gas phase or the LNG in the liquid phase. The handling and editing of the sample should be in accordance with the method in order for the measurement to remain representative.
LNG analysis benefit for Industrial
LNG testing results can help with various industrial needs, among other things:
- Gas Production and Production - Monitoring characteristic composition and quality products as part of process control.
- Storage and Transport - Support the quality evaluation of the product during the supply chain, according to the procedure and requirements.
- LNG Trading - Provides relevant data composition and energy to evaluate contract specs and surrender processes.
- Quality Control - Compare the analysis results to the specifications limit to help evaluate product quality consistency.
- Contaminan Evaluation - Identify certain compounds that need to be controlled based on the need of process, equipment, and customer specs.
- Energy Context Evaluation - Using composition data to support Taylor's calculations as one of LNG energy evaluations.
Interpretation Test LNG
LNG analytics need to be interpreted based on the current purpose of testing and specifications. Composition obtained not only as information about component content, but it can also be input for property calculations and product quality evaluations.
Hydrocarbons composition
Other methane distribution and hydrocarbons give us an idea of LNG composition.
Gross Heating Value and Net Heating Value
GHV and NHV describe energy value based on a different basis of calculation. Interpretation should pay attention to methods, units, and reporting bases used.
Impurities column
The contaminant testing results need to be compared to the limits set in product or contract specifications. The existence of a compound does not automatically indicate an discrepancy without considering the current limits.
Compatibility to Specification
The final evaluation is done by comparing the test results to the relevant requirements and considering the uncertainty of measurement and the terms of acceptance if required.
