These calculators execute entirely in your browser using published correlations. Each result includes the full traceable working. (Demonstration build — see verification note below.)
High-fidelity thermodynamic property prediction, real-time hydraulic sizing, and AI-assisted safety compliance — unified in a single offline-capable platform built for plant floors, EPC desks, and remote refinery sites.
Competitors hand you isolated property lookups. ProcessFlow Intelligence™ connects properties → hydraulics → safety → mechanical design into one auditable workflow.
Thermophysical properties across user-defined T & P ranges, not single-point lookups.
Every result shows formula, standard reference, and intermediate steps for verification.
Real-time API RP 14E erosion & relief-sizing alerts the moment limits are exceeded.
Audit-ready PDF / XLSX / CSV packages with hydrotest & passivation records.
27+ curated fluids with Rackett, Antoine, Lewis–Squires & Brock–Bird correlations, phase-envelope generation and Hansen solubility logic.
Single- and two-phase pressure drop, fitting resistance, and gas-transmission equations with elevation and compressibility corrections.
API 521 relief sizing, API RP 14E erosional-velocity screening, and ASME BPVC Section VIII Div.1 shell, head & MAWP calculations.
Rule-based assistant that validates inputs, flags hydraulic instability and erosion risk, and recommends safer operating ranges in real time.
Benchmarked against the leading process-engineering web tools.

Calculation methods reference established engineering standards and literature. Users remain responsible for verifying applicability to their specific design conditions.
ProcessFlow Intelligence™ v4.0 runs anywhere — plant floor, remote site, or your Aienginear.com workspace. Zero install, full offline capability.
The calculators on this page are working demonstrations of published correlations (Antoine, Rackett, Darcy–Weisbach / Swamee–Jain, API RP 14E, ASME VIII Div.1 UG-27). Property constants are drawn from standard references and may vary by source. Results are intended for screening, estimation, and educational use only and must not be used as the sole basis for safety-critical, relief, or mechanical-design decisions. All outputs must be independently verified by a qualified engineer against the governing code edition and the project's specific design conditions before use.
