Chromatograph of natural gas
Company EKNIS-ENGINEERING supplies of chromatographic complexes for automatic analysis of the molar concentration of natural gas components, calculation of its physical-chemical parameters according to DSTU ISO 6976: 2009 and transmission of information via an open digital protocol to an automated data collection and transmission system.
Measured components and measuring ranges are given in Table 1.
Table1. Natural gas components
|The name of component||Spectrum, %, moles|
|hexan and higher(C6+)||0-0,6|
|Carbon dioxide (CO2)||0-12|
The set of chromatographic complex includes the following nodes:
The chromatograph automatically calculates the following physical and chemical parameters of natural gas: the heat of combustion is higher, the density under normal conditions, Wobbe index at standard conditions.
Technical specialists EKNIS-ENGINEERING will provide all complex of chromatographic complex implementation works: installation and commissioning work, after-sales service.
Humidity meter of natural gas manufactured by Zegaz Instruments Inc
Dew point analyzer for water and hydrocarbons model DewPoint Duo™ manufactured by ZEGAZ Instruments that is the most advanced dew point measurement system, able to measure two parameters at the same time. Analyzer ZEGAZ Instruments is one humidity meter in the world that uses spectral method of dewpoint measurement. It exactly determines whether the condensate that has fallen out is moisture or hydrocarbons.
It is analyzing with accuracy ±0.5⁰C, device perfectly distinguishes between the dew point of water and hydrocarbons, and provides the highest measurement accuracy. The measuring principle is based on a patented method, infrared spectroscopy on the cooling surface.
The main advantages of measuring method Zegas:
• Non-metallic mirror:
- As the cooling surface uses crystal that is resistant to all contaminants, including acids, H2S, CO2, glycols, etc.;
- The little thermal mass of crystal, less power consumption, accordingly, a longer term of the cooling system;
- Extremely hard material, will not be damaged or scratched;
- No optical windows is excluded additional error.
• Spectroscopical method of determination laid-down condensation water:
- It can guarantee distinguishing between hydrocarbons and water based on IR absorption;
- Other components in natural gas aren’t influence readings.
Company ZEGAS Instruments produces the following models of analyzers:
- HCD5000 - On-stream analyzer that measure dewpoint of hydrocarbon;
- WDP5000 - On-stream analyzer that measure dewpoint of water;
- DewPoint Duo - On-stream analyzer that measure dewpoint of hydrocarbon and water;
- DewPort - Portable analyzer that measure dewpoint of hydrocarbon and water.
