Thermal desorption: the basics

Article Abstract:

Thermal desorption, which involves heating the soil, sediments and sludges in order to volatilize the existing contaminants, is emerging as one of the preferred means of treating hazardous waste. The procedure is classified into either a low-temperature or a high-temperature process. Thermal desorption has been proven effective in treating wastes that have been contaminated by volatile organic compounds, polycyclic aromatic hydrocarbons, semi-volatile organic compounds, polychlorinated biphenyls and fuels.

Cutting the strings: process automation goes wireless

Article Abstract:

A key subject of discussion during the ISA Expo 2007 was process automation going wireless, which can lead to low-cost, low-poer radios and robust protocols for wireless data. One of the issues in the convergence of these technologies is standardization. The history of process automation standards and current standards efforts are given.
