Chemical Engineering and Processing: Process Intensification is the premier publication for innovative research contributions on process intensification for chemical, biotechnological and functional materials manufacturing, energy, and environmental applications. The journal especially welcomes research contributions that aim for sustainable development. Articles should address progress on fundamentals, novel methodologies or practical chemical engineering applications, using, e.g., structured materials, miniaturized equipment, alternative energy sources for physicochemical activation (e.g., light, electricity, microwaves, plasma, and ultrasound), dynamics (e.g., periodic operation), external forcing (e.g., vibration, oscillatory flow), integrated separations and reactions, and other synergies between unit operations, as well as innovative process systems designs, digital manufacturing, and modularized production to achieve desirable targets, such as defossilization and higher resource efficiency, compactness, safety, and resilience.The journal has been endorsed by the Working Party on Process Intensification of the European Federation of Chemical Engineering (EFCE).Keywords: chemical process intensification, structured reactors, intensification of transport phenomena and separations, miniaturization, alternative activation methods, synergistic process integration, dynamic operation, digital manufacturing, digitalization, energy, environmental engineering, functional materials, sustainability, modularization.

Fees & open access
APC and open-access policy
Hybrid open accessLetPub
A subscription journal in which authors can pay to publish their article open access.
| Source | APC | Fee waiver | License | Observed |
|---|---|---|---|---|
