Photocatalytic membrane reactors: configurations, performance and applications in water treatment and chemical production

2013

Abstract: The configurations and performance of photocatalytic membrane reactors (PMRs) assembled with membranes (also photocatalytic type) and/or suspended photocatalyst are described. Examples of the application of PMRs in water/wastewater treatment as well as in photocatalytic synthesis are shown. An outline of the modeling of PMRs is presented with a brief economic analysis; future trends in PMRs are also discussed.

Industrial Dynamics Involving Electrochemical Processes

1985

Many industrial activities are based on electrochemical technologies, and several other receive from electrochemical methodologies useful or even decisive contributions for their development. There are important electrochemical industries in the fields of inorganic and organic chemical production, the treatment of metals, such as extraction, refining, finishing and processing, and the production of the various battery systems. Furthermore some electrochemical technologies are dependent on, and integrated with other industrial activities, and are related to corrosion control, water treatments, and environmental protection. Like physicians with their patients, these last applications have a p…

Global sea-to-air flux climatology for bromoform, dibromomethane and methyl iodide

2013

Volatile halogenated organic compounds containing bromine and iodine, which are naturally produced in the ocean, are involved in ozone depletion in both the troposphere and stratosphere. Three prominent compounds transporting large amounts of marine halogens into the atmosphere are bromoform (CHBr3), dibromomethane (CH2Br2) and methyl iodide (CH3I). The input of marine halogens to the stratosphere has been estimated from observations and modelling studies using low-resolution oceanic emission scenarios derived from top-down approaches. In order to improve emission inventory estimates, we calculate data-based high resolution global sea-to-air flux estimates of these compounds from surface ob…

Industrial Microreactor Process Development up to Production

2008

This chapter is about industrial applications of microprocess technology. Industry is not very active in publishing not only because of confidentiality reasons but also because of the absence of direct need for a corresponding profile. Thus, one cannot expect that the ongoing developments can be shown with a similar degree of completeness, clarity and detailedness, as this is possible for reviewing scientific contributions from academy with a wealth of peer-reviewed papers. Especially, the information of major interest of what has been transferred to production and how do the companies make profit with the new technology is usually kept secret. Thus, it has to be accepted that some informat…
