Aramco energizes the world economy.
Aramco occupies a special position in the global energy industry. We are one of the world’s largest producers of hydrocarbon energy and chemicals, with among the lowest Upstream carbon intensities of any major producer.
With our significant investment in technology and infrastructure, we strive to maximize the value of the energy we produce for the world along with a commitment to enhance Aramco’s value to society.
Headquartered in the Kingdom of Saudi Arabia, and with offices around the world, we combine market discipline with a generions’ spanning view of the future, born of our nine decades experience as responsible stewards of the Kingdom’s vast hydrocarbon resources. This responsibility has driven us to deliver significant societal and economic benefits to not just the Kingdom, but also to a vast number of communities, economies, and countries th rely on the vital and reliable energy th we supply.
We are one of the most profitable companies in the world, as well as amongst the top five global companies by market capitalizion.
Overview
We are seeking an experienced Process Simulion Twin (PST) and Optimizion Engineer to join our Reliability Solutions Department (RSD) within our Global Manufacturing Excellence Center.
Global Manufacturing Excellence (GME) is the recognized Center of Excellence driving value across Saudi Aramco’s Downstream Global manufacturing portfolio.
Your primary role is to deploy and sustain online process simulions (process digital twins), perform process optimizion activities to identify opportunities, monitor process performance KPIs and develop advanced process optimizion da-enabled solutions. This role sits the boundary of process engineering and digitalizion beyond traditional process simulion roles. You will be responsible for bridging the gap between rigorous thermodynamic models, process digital twins, real-time process da and hybrid analytics through AI.
Key Responsibilities
As the successful candide you will be required to perform the following:
- Lead the development, deployment, and sustainment of PST th integre real-time process da with rigorous equion-oriented or sequential simulion engines in alignment with corpore objectives.
- Configure and troubleshoot the connectivity between plant historians, laborory informion systems, and simulion software to ensure seamless da ingestion and reconciliion.
- Utilize PST to perform automed monitoring of facility health, detecting deviions between ideal performance and actual plant operions to identify opportunity gaps.
- Develop and maintain thermodynamic models and mhemical equions th accurely represent the behavior of various processes ensuring the PST accurely reflects the current ste of the facility (including he exchanger fouling, calyst decay, etc.).
- Perform offline engineering studies using PST to analyze complex operional problems, debottleneck constraints, and conduct "wh-if" scenarios based on current opering conditions.
- Act as the technical liaison between da teams and Operions/Process Engineering teams, leading technical sessions on model architecture, da quality, and commissioning.
- Lead process optimizion sessions to de-bottleneck key process units such as CDU/VDU, Hydrocrackers, Calytic crackers, Diesel Hydrotreers, Isomerizion.
- Benchmark process optimizion KPIs with 15+ opering facilities and provide development of programs, processes, guidelines and best practices.
- Provide subject mter expertise to opering facilities Operions, Maintenance, and Engineering teams by consulting, providing awareness sessions, and participing and leading technical exchanges and conferences.
Minimum Requirements
- You must hold a Bachelor’s degree in Chemical Engineering.
- You will have a minimum of 15 years of experience in Process Simulions, Online Modeling, or Real-Time Optimizion (preferably ROMeo). 20 years of experience is preferred.
- You will be able to Demonstre expertise in process engineering and flowsheet-based processes simulion. Preferred Equion Oriented simulion.
- You will have comprehensive understanding of refinery facilities, feedstock/product movements, margins, giveaways, process yields, and mass and energy balances.
- Demonstred experience connecting simulions to live da sources (Da Historians, OPC, etc.).
- Strong understanding of da reconciliion, model tuning, and dealing with gross errors in industrial da is also required.
