Energy Optimization & Green Energy Study for NGL Pumps – TIDAREC /Aramco Uthmaniyah Gas Plant
- Challenge
- High operating cost from fixed-speed pump and driver configurations
- Uncertainty between electric motor (VFD) vs gas turbine–driven pumps
- Load variations at forecast rates causing efficiency losses
- Need to balance energy cost, reliability, and CO₂ emissions
- No clear, data-backed comparison across pump, driver, and load scenarios
- AIGC Solution
- Built detailed HYSYS simulation models for NGL pump systems across UGP, UDER, HASHNGL, ShGP, and YNGLF
- AI-assisted comparison of fixed-speed vs variable-speed (VFD) pump configurations
- Evaluated electric motor–driven pumps against gas turbine–driven pumps under multiple operating scenarios
- Load management simulations at forecast throughput rates to identify optimal operating envelopes
- Integrated energy, cost, and carbon emission metrics into a single decision framework
- Realized Value
- Identified the most energy- and cost-efficient pump and driver configuration
- Quantified annual operating cost savings versus fixed-speed pump operation
- Clear recommendation on when VFDs outperform gas turbine drives and vice versa
- Reduced CO₂ emissions through optimized load and driver selection
- Provided implementation-ready, data-validated guidance for Aramco’s NGL pumping strategy
