Projects & Case Studies
Featured Study: Use of Hydrogen as a Fuel Input in Cement Manufacturing
A conceptual feasibility, process safety, and combustion dynamics analysis examining 10%–25% thermal energy substitution of fossil coal with industrial hydrogen in high-temperature cement kilns.
Challenge: Clinker calcination requires flame temperatures exceeding 1,450°C. Hydrogen burns with a laminar flame speed 8x faster than methane, has low volumetric energy density, and produces water vapor with lower radiant heat emissivity than luminous coal flames.
Process Safety: Highlights ASME B31.12 hydrogen piping compliance, Class I Div 1 explosion proofing, and burner exit nozzle velocities exceeding 45 m/s to prevent dangerous burner flashback.
Additional Verified Plant Case Studies
- Phosphoric Acid Slurry Pump Cavitation Fix: Reconfigured suction manifold to eliminate short-radius elbows, boosting NPSHa by 1.1m and dropping vibration from 14.2 to 1.8 mm/s.
- Rotary Kiln Main Drive Gearbox Overhaul: Compensated for thermal pedestal lift using cold alignment pre-offsets, improving tooth contact from 42% to 88%.
The 6-Stage Case Study Methodology
- Define Challenge: Operational baseline and financial impact.
- Investigate Evidence: Physical records, vibration spectra, and oil assays.
- Evaluate Options: Technical feasibility and safety trade-offs.
- Review Risk: Statutory codes, HAZOP, and metallurgy limits.
- Measure Outcome: Verified measurements vs projections.
- Share Lessons: Institutionalizing knowledge in CMMS procedures.
