Refining & Optimization Specialist – Linear Programming
role at Aramco.
Aramco occupies a special position in the global energy industry. It is one of the world’s largest producers of hydrocarbon energy and chemicals, with among the lowest upstream carbon intensities of any major producer. With significant investment in technology and infrastructure, Aramco strives to maximize the value of the energy it produces and enhance its value to society.
Key Responsibilities
Run LP models for existing and new refineries to identify areas for operation optimization and configuration. Use of LP models to identify margin improvement opportunities and develop business cases.
Run LP models to validate and support optimization initiatives and studies generated by Global Manufacturing Excellence for the assets in aid of business case development.
Improve refinery LP models and capture added value through validation processes.
Provide technical advisory support to refinery management and staff on various LP and optimization matters, such as crude selection, product slate, process units, and operational constraints. Communicate the LP results and recommendations effectively and persuasively, and follow up on their implementation and monitoring.
Coordinate and collaborate with other GOD engineers, analysts, and stakeholders such as refinery engineers, planners, schedulers, and marketers to ensure alignment and integration of LP models and objectives.
Validate and calibrate LP models using historical data and refinery test runs, ensuring models reflect current and future operating conditions and constraints. Document model changes and updates, and communicate them to relevant stakeholders.
Support the development and maintenance of the global MPIMS model, integrating all wholly owned refineries and global crude and product markets. Use MPIMS to optimize crude allocation and product slate for the global manufacturing network and identify optimal integration options and market opportunities.
Participate in the LP gatekeeping process for wholly owned refineries and the global MPIMS model, ensuring quality and consistency of LP models and data. Review and approve LP model changes and updates submitted by refinery LP engineers, providing feedback and recommendations as needed.
Minimum Requirements
Bachelor’s degree in Chemical Engineering. Advanced degree preferred.
Minimum of 15 years of LP experience in refining or gas plants (LP modeling, optimization, and economics).
Proficiency in PIMS, Aspen HYSYS or PetroSim software, and other relevant tools and standards.
Developed rigorous simulation for refining process units such as Hydrocracking, FCC, DHT, CCR, and delayed coker, and built a rigorous simulation model of a complete refinery.
Developed integration between rigorous simulation models and Aspen PIMS. Experience in running LP models for complex integrated refineries, conducting scenario analysis and sensitivity studies.
Strong knowledge of engineering practices, economic principles and calculation methods.
Solid understanding of refining processes and economics, as well as global crude and product markets and trends.
Ability to work independently and collaboratively in a fast‑paced, dynamic environment, managing multiple projects and tasks simultaneously.
Strong presentation and reporting skills, communicating complex technical information clearly and concisely.
Strong initiative, creativity, integrity, and leadership qualities. Able to identify and seize opportunities for improvement and innovation, and lead people toward excellence and optimization.
