Characteristics of an Intensified Green Process

• Gives every molecule the same processing experience• Matches the mixing and transport rates with the

reaction rate. Offers significant enhancement in heat & mass transfer rates

• Allows the reaction to run at the speed it wants to run and not the speed at which the equipment permits it to run

• Improves selectivity, yield, quality• Rapid response to set-points• For certain processes, the laboratory scale may be the

full scale• Reducing The number of processing steps by using

multifunctional modules
