๐ Overview
The Wax Deposition Predictor estimates the risk and potential thickness of wax deposits in pipelines based on fluid and thermal parameters. It lets you select units, calculation methods, and includes code-based risk logic.
๐งพ Inputs
- Pipeline Wall Temperature: ยฐC, ยฐF (selectable)
- Wax Appearance Temperature (WAT): ยฐC, ยฐF (selectable)
- Paraffin Content/Oil Wax Fraction: % or fraction (selectable)
- Flow Rate: mยณ/h, bbl/d, L/s (selectable)
- Pipeline Length: m, km, ft, mi (selectable)
- Calculation Method/Code:
- API 14J
- ISO 13623
- DNVGL-RP-F110
- Empirical/Field
- Output Deposit Thickness Unit: mm, inch
๐งฎ Calculations
- All units converted to SI for computation.
- Deposit thickness estimation: d=ktimes(WATโTwall)timesfwaxd = k \\times (WAT – T_{wall}) \\times f_{wax}d=ktimes(WATโTwallโ)timesfwaxโ Where ddd is predicted wax thickness, kkk is a method-dependent factor, WATWATWAT is wax appearance temperature, TwallT_{wall}Twallโ is pipeline wall temp, fwaxf_{wax}fwaxโ is wax fraction.
- Flags high risk if wall temp is below WAT and oil is waxy.
๐ค Outputs
- Acceptance Status: โ No significant risk, or โ ๏ธ Wax risk โ review mitigation
- Estimated Wax Deposit Thickness: In selected unit
- Input Summary: Key parameters and risk message
