1 Introduction. To the best of the author's knowledge, the term "process intensification" (PI) was used for the first time in a polish journal (Leszczynski 1973).PI saw a boost at imperial chemical industries (ICI) in the eighties by Prof. Ramshaw's group (Ramshaw 1983, Law et al. 2017).Their work has been continued at the University of Newcastle (homepage: ).
Microchannel is a basic structure of a microreactor system with some additional parts needed for its functionality. One of them is solid base material on which microchannel is positioned (microchannel and base together form a chip) and connecting fluid lines that, together with the chip, form a microreactor unit (Fig. 1).Biochemical processes and biotechnology itself are never simple.
