Abstract

The process industries are energy intensive, mostly fossil fuel fired, and are considered difficult to decarbonize. As more electricity is either renewable or otherwise carbon free, powering more process industry operations with electricity becomes a decarbonization strategy. Thermal energy is required for increasing temperature, phase change, and endothermic reaction. Electricity can generate heat via resistance, induction, dielectric, arc, and gas compression mechanisms, among others. Electrically generated heat can be delivered with high precision and tight control. Furthermore, electricity can power the elevation of heat from lower temperatures to higher temperatures. Electricity can also facilitate chemical reactions that are thermodynamically difficult, especially the electrolysis of water to produce hydrogen. The key will be to match the right electrical heating technology at the right temperature with the right application at the right scale.

通过电气化实现工艺脱碳
加工工业是能源密集型行业,大多以化石燃料为燃料,被认为难以实现去碳化。随着越来越多的电力成为可再生能源或无碳能源,用电力为更多的加工工业运作提供动力成为一种脱碳战略。升温、相变和内热反应都需要热能。电能可通过电阻、感应、电介质、电弧和气体压缩等机制产生热量。电能产生的热量可以以高精度和严格控制的方式输送。此外,电力还能将热量从低温提升到高温。电还可以促进热力学上难以进行的化学反应,特别是电解水产生氢气。关键在于在合适的温度下,将合适的电加热技术与合适的规模、合适的应用相匹配。

期刊介绍: Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
