The book, The Business of Scaleup, is made up of three parts. The first is a review of engineering scaleup procedures, similar to those published in Process Scaleup and Design. Additional stories have been added. The second is a research paper that provides an example of a process scaledown. The main conclusions from these two discussions are that: 1) geometric similarity can be a hinderance to an effective and profitable design and 2) simple scaledown studies can provide significant insight...
