This article covers permitting and directly related design issues associated with thermal processes used for drying and calcining, using the production of ceramic proppants as an illustrative example. While the magnitude of permitting issues varies significantly with air-quality attainment area status, oxides of nitrogen (NOx), carbon monoxide and particulate matter are always the major issues. With proper...

This month marks the 40th anniversary of the Clean Water Act (CWA), the primary federal law regulating discharges of pollutants into U.S. waters. As far as the developed world’s water priorities go, a great deal has changed since 1972. For one thing, the top challenge back then was eliminating releases of toxic substances. Today, that challenge is arguably being met, and we are now getting more...

In designing and sizing relief-device and effluent-handling systems, one commonly overlooked aspect of the performance is examining the potential for low temperatures that can cause the components of the system to reach temperatures below their respective, minimum-design metal temperatures (MDMT), which may result in brittle fracture with subsequent loss of containment. This article points out limitations...
