See the Proven Solution| Parameter | Typical Range (by region) | Unit | Impact on Equipment |
|---|---|---|---|
| Methane (CH₄) | 84‑97 | vol % | Primary calorific value; determines burner sizing. |
| Ethane (C₂H₆) | 1‑8 | vol % | Raises Wobbe index; influences turbine inlet temperature. |
| Propane (C₃H₈) | 0‑4 | vol % | Higher heating value; affects compressor pressure ratios. |
| Butane (C₄H₁₀) | 0‑2 | vol % | Viscosity increase; may cause valve‑seat wear. |
| Nitrogen (N₂) | 0‑5 | vol % | Dilutes calorific value; impacts flow‑meter calibration. |
| Carbon Dioxide (CO₂) | 0‑3 | vol % | Corrosive to steel; requires carbon‑steel‑compatible alloys. |
| Hydrogen Sulfide (H₂S) | 0‑0.2 | vol % | Highly toxic; mandates H₂S‑resistant seals and monitoring. |
| Water Vapor (H₂O) | 0‑2 | vol % | Condensation risk; need dehydration units. |
| Oxygen (O₂) | 0‑0.5 | vol % | Supports combustion; excess leads to NOₓ formation. |
Natural gas is dominated by methane (CH₄) (≈84‑97 % vol). It also contains ethane, propane, butane (C₂‑C₄ hydrocarbons), inert gases such as nitrogen (N₂) and carbon dioxide (CO₂), and trace amounts of hydrogen sulfide (H₂S), water vapor, and oxygen (O₂). Exact percentages vary by field and processing method.
Higher CO₂ or H₂S levels demand corrosion‑resistant alloys (e.g., 316L stainless steel). Ethane and propane raise the Wobbe index, requiring turbines with broader combustion‑stability margins. Nitrogen dilutes calorific value, influencing flow‑meter calibration. Our OEM designs incorporate these variables, eliminating costly retrofits.
