Hybrid and Combined Processes for Air Pollution Control: Methodologies, Mechanisms and Effect of Key Parameters

Description

Hybrid and Combined Processes for Air Pollution Control: Methodologies, Mechanisms and Effect of Key Parameters provides an exhaustive inventory of hybrid and combined processes in the field of air treatment. The book covers principles, the effect of key parameters, technologies and reactors of the processes and their implementation, from lab-scale to industrial scale, also identifying future trends. Sections discuss effects on the environment and living beings, identify novel techniques and innovations, and offer a thorough assessment of the strengths and weaknesses of each. In this well-structured book, chapters are linked to the type of treatment, with a significant part dealing with treatment by transfer processes: (absorption and absorption) and on destruction treatments, such as advanced oxidation processes.
