Result stream
Key features
• Side-by-side component entry with inline units keeps Mixture A/B tidy. • Shared pressure/temperature inputs document test conditions for QA reports. • Additional components collapse away until needed, mirroring lab worksheets. • Result table highlights signed deltas plus the average absolute deviation.
Typical applications
• Pipeline interchangeability checks prior to custody transfer. • Fuel gas blending decisions for turbines or heaters. • Lab vs. contract spec comparisons when validating chromatograph calibrations. • Process optimization studies focused on heavier fractions or inert build-up.
How to use the tool
1. Set pressure and temperature so both samples reference identical conditions. 2. Fill primary components for Mixture A (left) and Mixture B (right). 3. Expand Additional Components when heavier fractions or inert gases matter. 4. Click “Run process” to compute component deltas and overall deviation. 5. Review insights for totals, outliers, and any imbalance warnings.
Usage example
Example: Compare a contract spec (Mixture A: 85% CH₄, 6% C₂H₆, 2% C₃H₈) against a field sample (Mixture B: 82% CH₄, 7% C₂H₆, 2.5% C₃H₈) at 55 bar / 25 °C. The output surfaces the heavier propane content in Mixture B and quantifies the Δ% so you can decide whether to reroute or blend.
FAQ
Q: Why align temperature and pressure? A: Documented conditions make lab write-ups defensible and simplify references to density or Wobbe calculations. Q: Do totals need to hit 100%? A: The comparator allows +/-5% tolerance and flags imbalances so you can double-check chromatograph cuts. Q: What if I need heating value or Z-factor? A: Use the delta report as a screening step, then export data into your thermodynamic package for full calculations.
