This is the major international forum for the discussion of technical aspects of scale-up at the chemistry/chemical engineering interface. Topics include: the scale up of batch and semi-batch processes, continuous processing and reaction engineering, microreactor technology, safety and thermochemistry, scale up of potentially hazardous chemistry, green chemistry, quality assurance and regulatory concerns, solid form control (crystallisation and polymorphism), separation and purification techniques, and new technologies and equipment for large scale manufacture.
