Process intensification physical

Figure 7.1 Relationship between process intensification fields, physical process intensification, process miniaturization, selectivity, process viiibility, and phenomenon-based...

Process intensification is commonly defined as Technologies and strategies that enable the physical sizes of conventional process engineering unit operations to be significantly reduced. This is achieved through ... 

Phillips of the BHR Group, UK, provides a compact definition of process intensification, saying it is ... a design philosophy whereby the fluid dynamics in a process are matched to its chemical, biological and/or physical requirements,. .. [27]. In this way, significant benefits are gained, those listed above. 

Microreactors evolved from the process intensification concepts and microfabrication techniques developed for the microelectronics industry. Process intensification was pioneered in the 1970s, arguably by Imperial Chemical Industries (ICI) researcher Colin Ramshaw, who began developing technologies and approaches that considerably reduced the physical size of unit operations while maintaining their... 

With this vast variety, it is usually possible to tailor the solvents to specific chemical reactions. Ionic liquids have a range of physical chemical properties that can be tuned with a precision that is hard to imagine for a given reaction. Ionic liquids are good solvents for a wide range of inorganic, organic, and polymeric materials. There are ionic liquids that will dissolve covalent compounds. Ionic liquids can lead to process intensification.

The example explained in the following illustrates process intensification at the level of basic chemical and physical processes. Again, it concerns an equilibrium reaction, in which the equilibrium is strongly on the educt side and a slightly volatile component has to be removed from the system to displace the equilibrium. However, the equilibrium does not occur spontaneously, so the use of a reaction column is not possible. Therefore, a high-stress field develops with high yield and duration of thermal stress.
