Online natural gas calorific value tester

1、 Instrument functions
According to the national standard GB/T13610-2003 "Gas Chromatography for Component Analysis of Natural Gas", Tengzhou Zhongke Spectral Analysis Instrument Co., Ltd. has developed a "Natural Gas Online Monitoring Instrument" with the following specific functions:
1. A. Use highly sensitive dual thermal conductivity, one thermal conductivity to measure H2, O2, N2, CH4 are measured for CO2, ethane, propane, isobutane, n-butane, neopentane, isopentane, n-pentane, and hexane.
B. The thermal conductivity sensitivity can reach 26000mv. ml/mg. The small detection concentration is 0.04%.
2 . A. One time automatic injection for full analysis, displaying all tested components on a single analysis spectrum;
B. The double ten way sampling system, equipped with a pre column blowback device, effectively extends the service life of the analytical column.
3 A. Natural gas is introduced into the chromatography chamber through a bypass in the pipeline to achieve real-time detection of the quality of the flowing gas in the pipeline. The instrument can be remotely operated through a network cable in the control center.
B. There is a 24-hour automatic timed cycle analysis function, and the analysis data can be automatically saved and sent to remote files;
C. It can automatically compile a long-term content change table for six components, providing reliable data for understanding the quality changes of natural gas.
4 . A. A reliable self checking system enables the instrument to operate online for a long time, such as automatically shutting down when there is no carrier gas, avoiding damage to the instrument.
B. Only H2 and Ar gases are needed as carrier and power gases, making the operation simple and convenient;
C. Intelligent peak detection method, suitable for long-term operation of instruments.
2、 Instrument features
1. The instrument is equipped with a built-in hydrogen generator, with high electronic circuit integration, good reliability, and simple operation, ensuring stable and reliable instrument quality. It can operate continuously for a long time, which not only ensures work efficiency but also saves maintenance costs. It automatically memorizes operating parameters and does not require resetting when starting up.
2. Equipped with a gas cut-off protection system to prevent instrument damage caused by misoperation.
3. The gas path system adopts a high-precision valve structure, which greatly improves the stability of the instrument gas flow rate, thereby obtaining well reproducible analysis results.
4. It can synchronously analyze the content of various components such as oxygen, nitrogen, carbon dioxide, methane, ethane, propane, isobutane, n-butane, isopentane, n-pentane, etc. in natural gas. Content range: 0.01%~. Calculate the calorific value, white number, density, etc. of natural gas based on the content of each component.
5. It can be used in the laboratory or online.
6. Equipped with a four arm thermal conductivity detector.
7. Configure chromatographic columns for good separation efficiency.
8. The instrument can be used for composition analysis of natural gas and liquefied gas mixtures, as well as for analysis of various gas components using hydrogen, nitrogen, and methane as raw materials.
9. After a sample analysis, the instrument can report characteristic indices such as the composition content, high calorific value, and low calorific value of the measured gas through a customized report
10. The instrument is suitable for all occasions that require testing the composition of natural gas, such as LNG refueling stations, LNG gasification stations, urban gas reserve stations, gate stations, etc
3、 Requirements for calorific value of natural gas
1. Natural gas has a high calorific value of 8500-8600 kcal/standard cubic meter and a gasification rate of 1480-1490 cubic meters. It is suitable for many users such as storage and distribution stations, gasification stations, and point supply users.
2. The low calorific value is over 8800 kcal, with a gasification rate of around 1400 cubic meters, suitable for LNG refueling stations and some point supply users; But not suitable for gasification stations
3. LNG mixed with 1 ton of liquid nitrogen has a nitrogen content of 4.6% and a low calorific value of 8100 kcal,
The gasification rate is over 1400, but nitrogen does not burn and the total calorific value is low.
