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 reliable determine natural gas quantitatively and quantitatively. For this application, Modcon offers complete natural gas quality control systems, equipped with modern analytical instruments and everything needed for fast and accurate analysis of sample probes from the gas pipeline.

Natural gas quality online analytical system model MOD-1020 has been designed for continuous measurement of the following quality characteristics of natural gas:

  • Gas chemical composition, molecular weight, Wobbe index, and Upper Calorific Value – CV, which is the latent energy content of a gas that is released during combustion.
  • Concentration of Hydrogen Sulfide (H2S) content in natural gas
  • Hydrocarbon Dew Point (HDP) is a temperature at which higher hydrocarbons condense. Liquid phase is produced in the gas pipeline if the hydrocarbon dew point is fallen below. The accumulation of liquid in the pipelines can lead to a plug flow and may destroy the compressors in the pumping station

Water Dew Point (WDP) is the temperature at which water condenses out. Water together with hydrocarbons favors the generation of solids, in particular during the decompression of gas from high-pressure pipelines. The solids block gas fittings, and the water is corrosive.
