Natural gas is a complex mixture of various organic and inorganic components and component groups. A differentiation must be made between flammable hydrocarbons as the actual source of energy and non-flammable components.
The wide range of components makes it difficult to reliably determine natural gas qualitatively and quantitatively. For this application, Cemtrex offers complete natural gas quality control systems, equipped with modern analytical instruments and everything needed for fast and accurate analysis sample.
- Continuous sampling of gas from pipeline or process vessel, its filtration and separation from accompanying impurities (solid particles, salts, oils, aerosols of liquid hydrocarbons, glycols, amines etc.)
- Sample preparation for analysis of physical and chemical parameters according to specifications of analytical devices (incoming gas temperature, pressure, flow rate etc.)
- Analysis of critical gas parameters, which are necessary for assessment of its quality and suitability for processing, transportation and use
- Transfer of analysis results to customer’s gas processing facility control room by means of electronic communication
- Automatic gas leak detection and indication of dangerous gas concentration levels in analyzer house
The system includes following main components:
- On-line gas-chromatograph, hydrocarbon dew point, water dew point and H2S analyzers
- Sampling system, including high-pressure gas probes for taking samples from pipelines and process vessels, membrane flters-separators for gas separation from liquids and aerosols, absorption flter-scrubbers for glycols and amines, pressure regulators, release valves, flow meters and flow regulators, 2- and 3-way valves and tubing – all made of SS-316
- Weather-proof analyzer housing for accommodation of all major System components and providing suitable working conditions according to their specifcations
- Electrical infrastructure, including main power switches, power distribution boards to analyzers and to peripheral equipment (lighting, heating, AC), signal terminal box, light switch, armored cabling – all Ex-proof
Applications:
- Natural gas quality analysis
- Import and export metering stations
- Gas condensation and pipeline corrosion prevention
- Transfer of analysis results to customer's gas processing facility
- Analysis of critical gas parameters
