Performance data acquisition in representative industrial-scale conditions is a key step in the development of new processes. More often than not, it requires pilot-scale experimentation. Thermal and matter transfers must be fully controlled on this scale, given extrapolation factors in the region of 105 to 106 between a pilot facility reactor and an industrial unit reactor. For highly technological processes, an intermediate scale (102 to 103) may be necessary to make extrapolation as reliable as possible in economic, technical and operational terms.
IFPEN’s Process Experimentation Division is involved at all phases on both these scales: design, launch, production start-up, data processing and plant maintenance. It has a pool of 75 pilot units at the IFPEN-Lyon site, covering all IFPEN applications involving catalytic and/or separation processes. On average, it works on one to four demonstrators per year located on industrial sites.
To reinforce its expertise supporting this experimentation, the division relies on fundamental research centered around three main areas:
online analysis for real-time control of units,
data sciences including Artificial Intelligence to optimize the conduct and operation of pilot tests,
control of physical and chemical phenomena within these facilities for the acquisition of representative data.
This issue of Sciences@IFPEN, dedicated to the “Process Experimentation” Division, presents six articles illustrating our developments in these three areas.
The design of pilot tools for advanced plastics recycling will be presented through a major infrastructure: the PROPRE platform. Two highlights concerning online analysis techniques will illustrate the essential aspects of characterizing and controlling these same plastics recycling processes.
The digitalization of pilot units and an example of the use of AI to transfer knowledge from a historical domain to a new information technology domain will then be presented.
Finally, we will showcase the use of numerical tools such as computational fluid dynamics, essential for understanding and controlling the physical phenomena at play in pilot units.
We hope that you enjoy this issue,
