Special Issue Information

Dear Colleagues,

In June of 2019, a group of experts from academia, industry, governmental agencies, technical societies, and institutes gathered in Leiden ( Netherlands) to among other topics, discuss the role of process intensification (PI) as an essential tool in the context of the United Nations Sustainable Development Goals. It was proposed to update the definition of IP to move it away from a narrow view too focused on size and efficiency. First, PI should be viewed as an approach “by function”, instead of the conventional process design by unit operations. By looking at a process from the function perspective, it is possible to design multifunctional or hybrid units that enable PI's objectives to be achieved. Second, an approach that focuses not only on the process itself but also on what happens “outside or as a consequence of the process”. In this context, any action directed to improve a process performance should consider its impact on the environment through increased emissions, on the process economics through increased fixed and operating costs, and on the complexity of the processes through increased technical and safety risks. In summary, the focus of PI should be redirected to the sustainability of the chemical processes.

This Special Issue on “Novel Approaches for Chemical Process Intensification” aims to collect high-quality research studies addressing innovative ways of thinking about the intensification of chemical processes from a sustainability point of view.

To identify the microwave drying characteristics of corn, microwave drying tests were conducted on corn. By taking the moisture content, drying rate, and drying temperature as indices, this research revealed the effects of different microwave powers and loads on the microwave drying characteristics of corn. Moreover, energy consumption and quality of dried corn were analysed under different drying conditions. The results demonstrate that microwave drying has significant energy-saving effects. The energy consumption by microwave drying is less than 0.3 times that used by electrothermal drying under the same load. Both microwave power and load exert significant influences on drying characteristics. Higher microwave power results in a greater average drying rate, wherein shorter periods of time are required to reach the maximum drying rate and higher temperatures of the corn. However, the load shows the opposite tendency. The smaller the load, the higher the temperature of the corn in the early stage of drying. However, as drying continues, the temperature curve changes significantly, and the temperature rises with the increase in load in the later stage of drying. In consideration of energy consumption and dried quality, the load of corn should be increased as appropriate, and the microwave intensity should be limited to no higher than 0.7 W/g in the experiment.
