Energy Optimization & Green Energy Study – WOODPLC / Aramco Gas Increments Program 2025
- Challenge
- High energy consumption across gas processing units leading to increased OPEX
- CO₂ emissions driven by sub-optimal heat integration and utility system design
- Multiple design improvement options with no clear economic prioritization
- Inefficient pump sizing, exchanger design, and CHP configuration affecting overall efficiency
- Difficulty evaluating trade-offs between energy savings, emissions reduction, and NPV
- AIGC Solution
- Developed an integrated process and energy model covering major gas plant units and utilities
- AI-assisted optimization of pump numbers, sizing, and operating points
- Advanced heat exchanger network analysis to improve heat recovery and reduce utility demand
- Comparative evaluation of combined heat and power (CHP) configurations to identify the best-fit option
- Gas turbine and hot oil system simulations to balance efficiency, reliability, and emissions
- Automated techno-economic analysis to calculate NPV for each design improvement scenario
- Realized Value
- Significant reduction in overall energy consumption across the gas plant
- Measurable CO₂ emissions reduction aligned with Aramco sustainability targets
- Optimized CHP selection delivering higher efficiency and lower lifecycle cost
- Capital investments prioritized using clear NPV-based decision making
- Practical, implementable recommendations jointly validated with Aramco energy engineers
