In the chemical industry, just in time delivery and ever more efficient processes are prime requisites for competitiveness. High end products require a wide product diversity resulting in lower quantities of each single product. The answer to the problem are multiproduct plants designed to meet changing requirements. Already at design stage, different potential requirements are taken into consideration allowing technical equipment to be installed according to the desired product. Reconfiguration can be achieved quickly through exchange of readily available components without costly refitting of the entire plant. This is the first comprehensive source of information on this modern topic, treating the different concepts known for multiproduct plants, their technical realization, possible uses for the production of chemicals, the choice of the construction materials, as well as safety considerations.
