This paper discusses the design and analysis of an experiment performed in a continuous process (CP). A full factorial design with replicates is used to test three types of pellets on two levels of a process variable in an experimental blast furnace process. Issues and considerations concerning the experimental design and analysis are discussed. For example; an adaptive experimental design is used. We propose a multivariate approach to the analysis of the experiment; in form of principal component analysis combined with analysis of variance. The factorial design in CPs is found to have a promising potential. However; CPs also demand special considerations when planning; performing and analyzing experiments; and therefore further development of experimental strategies and connected methods of analysis for CPs is needed.
