Bulk solids are frequently used as reactants, catalysts or products in chemical process industries (CPI) operations. Often, they must be heated or cooled so that they can be handled safely or processed at a desired temperature. Traditionally, heat transfer to or from powders is carried out using heated or water-cooled screws, fluidized beds or rotating drums. However, a more economical means of heating or...

Methionine is an essential amino acid that is not synthesized by animals, so it must be obtained from their diets. Synthetic methionine is traditionally commercially available in two varieties: D,L-methionine (DLM), a racemic mixture of the two stereoisomers, and methionine hydroxy analog (MHA). For animal nutrition, the two are equivalent. Globally, 98% of methionine produced is used as an animal feed...

Reactive chemicals and intermediates are used extensively in the chemical process industries (CPI). Hazardous chemical reactivity can be defined as “any chemical reaction with the potential to exhibit rates of increase in temperature and/or pressure too high to be absorbed by the environment surrounding the system” [1]. Reactive materials can be classified into two groups: self-reacting...
