Vingt ans du SPI (département des Sciences pour l'ingénieur du CNRS) et l'émergence du génie des procédés

During the second half of the XXth century, chemical engineering, by becoming a scientific discipline, was able to solve numerous problems raised by the chemical industry. Its extension towards new fields of application was achieved by generalizing concepts that apply to any process for the transformation of matter and energy: it thus developed into process engineering. It is explained how this discipline was able to adapt itself to new requirements both by continuing its own inherent evolution and by exchange with other disciplines
