The worldwide trend to produce low sulphur and low aromatic gasoline and diesel, and to process heavier crude oils in general, places increased demands on refinery hydrogen systems.

Meeting the resulting increased demands for hydrogen can require significant capital investment in, for example, steam reformers and compression equipment. Yet, most refinery hydrogen systems are inefficient and have significant room for improvement. By modifying the hydrogen network and considering alternative hydrogen recovery options, refiners can often satisfy the increased demands for hydrogen with significantly reduced investment.

Alternatively, refiners can improve the operation of currently operating hydrogen systems, to make them more efficient and significantly reduce their running costs.

PIL has completed a number of successful hydrogen studies where significant cost opportunities have been realised in the hydrogen management system. This 2-day course presents the techniques used in such studies so that attendees can check the efficiency of their own hydrogen systems and identify improvement opportunities themselves.

Who Should Be Trained?

The course is intended for people with a chemical engineering background working in the petroleum industry, or in engineering and consultancy companies, servicing the industry. Process engineers and refinery managers with an interest in improving hydrogen management should attend this course.
