makes these processes similar, you can eliminate many scale-up problems. A rational approach to scale-up has been used in physical sciences, viz. fluid. dynamics and chemical engineering, for quite some time. This approach is based . on process similarities between different scales and employs dimensional analy -. Towards this end, recent experimental and engineering efforts have been devoted to the implementation of continuous MSMPR crystallisers for pharmaceutical and fine chemical compounds. For example, Sen et al. [9] optimised the start-up of a continuous pharmaceutical manufacturing process, wherein the cooling. 7 Nov This allowed us to rapidly produce many different prototypes and to optimize experimentally key design aspects in a time-efficient fashion. This excellent flow distribution was crucial to scale up a model reaction efficiently, displaying yields comparable to those obtained in a single-channel device. We also.

The use of dimensional analysis to scale-up mechanically agitated flotation processes and to identify first order kinetic models expressing recovery (R) as a function of time (τ) such that: R = Rm (1-e-kτ).

Hydrogen can be com- pressed and reversibly stored in tanks through chemical or . ). The major challenge for development of such systems is their scale- up. Scale-up of manufacturing processes for nanostructures to technological scales has.
