Fascinating Facts About Thermal Pollution Control... 

The system described here also includes consideration of environmental concerns other than water pollution control, namely, the use of wastewater for air and thermal pollution control functions and waste residue usage for heat and power production and/or water treatment (ash and sludges). However, even an ideal plant system will have a net discharge of some waste material. The system described in Fig. 3.14 includes excess ash from thermal power production and wastewater blowdown of high salinity, hardness, and toxicity. These wastes may be blended for some beneficial purpose, to ease proper handling, or for controlled assimilation by the environment in appropriate disposal sites. These concerns will have to be given consideration as industry proceeds to meet future environmental demands.

Commercially available thermal oxidizer systems are pre-engineered, that is, the equipment is designed on the principle that in order for the equipment to be competitive in the marketplace, then a series of products of fundamentally standard designs are tailored to the application by changing some of the parameters as dictated by the requirements. This is not always the case with other pollution control systems, as oftentimes custom built-systems are specified. Since thermal oxidation equipment has a burner, the designs require controls for safety and operation. 

Air movement is ideal in the working zone, both for thermal comfort and pollution control. 

Many compounds can cause problems in pollutant-control equipment. Particulate matter, liquids, or solids in the waste stream can plug the adsorber beds, heat-recovery beds in regenerative thermal incinerator systems and biofilters. Conventional filtration systems are used to remove particulate matter before or after the process. 

Supported metal catalysts are used in a large number of commercially important processes for chemical and pharmaceutical production, pollution control and abatement, and energy production. In order to maximize catalytic activity it is necessary in most cases to synthesize small metal crystallites, typically less than about 1 to 10 nm, anchored to a thermally stable, high-surface-area support such as alumina, silica, or carbon. The efficiency of metal utilization is commonly defined as dispersion, which is the fraction of metal atoms at the surface of a metal particle (and thus available to interact with adsorbing reaction intermediates), divided by the total number of metal atoms. Metal dispersion and crystallite size are inversely proportional nanoparticles about 1 nm in diameter or smaller have dispersions of 100%, that is, every metal atom on the support is available for catalytic reaction, whereas particles of diameter 10 nm have dispersions of about 10%, with 90% of the metal unavailable for the reaction.
