Tank Venting Api2000: correction_factors
API Standard 2000 (7th Ed 2014) tank venting requirements — normal thermal inbreathing/outbreathing SCFH by tank volume (100–180,000 bbl), pump-in/pump-out liquid movement venting rates, emergency fire-case venting by wetted area (100–2800 ft2), flash point and latitude correction factors, insulation credits, conservation vent set pressure/vacuum settings, and vent type selection guidance for atmospheric and low-pressure fixed-roof storage tanks
| venting scenario | record id | notes | parameter category |
|---|---|---|---|
| correction_factors | flash_point_correction | Flash point correction factor for normal outbreathing: FP >= 100F -> outbreathing = 60% of inbreathing rate (thermal only); FP < 100F -> outbreathing = 100% of inbreathing rate; pump-in rate doubles for FP < 100F (12 vs 6 SCFH/BPH) | correction_factors |
| correction_factors | insulation_credit | Insulation credit for thermal breathing: insulated tanks (thermal resistance R >= 4 hr-ft2-F/BTU) may reduce venting rate by up to 75% per API 2000 Annex A insulation factor; must demonstrate insulation maintenance; credit not allowed for fire case | correction_factors |
