Membrane reactors production economical analysis

When producing high value biochemicals, the economic analysis is, generally, more favorable for the MBR systems, when compared with the more conventional units. Often selectivity rather than conversion may be the key, since higher selectivities typically result in the elimination of some of the purification steps which have a strong influence on the total production costs. The application of the multiphase/extractive enzyme membrane reactor for the production of a diltiazem chiral intermediate was reported in Chapter 4...

Abstract In this chapter, membrane bioreactors are described from an economic point of view. Economic analysis is a crucial stage in plant design, project and control and also requires an evaluation of the research, development and commercialization of the products and bioproducts. Such an analysis is focused here on membrane bioreactors and reactors, also taking into account the separation units such as micro-, ultra- and nano-flltration units that might be used as a downstream process or as pretreatment steps. The most important rules and parameters are first introduced. Some examples of application and case studies are also reported.
