Organizational Context and Job Purpose

Organizational Context:

INEOS is a global manufacturer of petrochemicals, speciality chemicals and oil products. Comprising 36 individual businesses, we operate 194 facilities in 29 countries throughout the world. 

With LAO manufacturing facilities in USA, Canada and Belgium, INEOS Oligomers is one of the largest merchant suppliers of Linear Alpha Olefins (LAO), which are used as co-monomers in polyethylene manufacture as well as in surfactants, lubricants and oil drilling fluids. Our technology has a clear competitive advantage over our competitors. Further developments of the technology are planned to be an integral part of this project.

Our markets are growing worldwide. Through selective investments in new assets and new technology, we intend to capture this growth to develop our business and grow with our customers. As part of this exciting growth strategy, we are investing in a new world scale production facility located in the Middle East. The plant capacity will be 420 KTA and is planned to come on-line in 2027.

Purpose of the job:

Under the direction of the Process Design Manager the Process Engineer will execute the development of the process heat and material balance, the process flow diagrams defining the process to be constructed, piping and instrumentation diagrams (P&ID’s) for the detailed process definition, equipment lists and specifications, and design of safety systems for the process.   The Process Engineer will work with the project team and engineering contractors to ensure that the process design and control systems design goals for the plant are met from inception to start up. This position will require extensive (over 60%) international travel to facilitate in-person involvement throughout the engineering and start-up phases.  This will be an expatriate position located in multiple international locations throughout project.
