Scaling up processes with Design of Experiments

Comparing scales to qualify the smaller reactor is crucial. Design of Experiments (DoE) is an extremely useful approach to check how the process behaves throughout the scale range, and can be combined with other techniques to provide a complete picture.

catalysis

Catalysis, the modification of the rate of a chemical reaction, usually an acceleration, by addition of a substance not consumed during the reaction. Each catalyst molecule may induce the transformation of many molecules of reactants. Learn about the history, classification, and reactions of catalysis.

Chemical Reactivity

Chemical Reactivity increases as you go down the group This happens because as you go down a group, it is easier for electrons to be taken or given away, resulting in high Chemical Reactivity. And you go from left to right on the periodic table elements have more electrons in their valence shells they have to get rid off which requires an element to have high energies which results into lower

Ultrasonic Homogenizers for Liquid Processing

While the scale-up of a process from the laboratory or bench-top level to full production is the most critical and hardest step for other mixing technologies, it is most simple with Hielscher ultrasonic equipment. This is because; during scale up we do not change any of the driving parameters, such as amplitude or pressure. Ultrasonic batch mixing works well for volumes of up to 100L for some
