There is an emerging crisis brewing for the chemical processing industries (CPI) in many regions of the world. Those regions include China, the world’s manufacturing powerhouse; swaths of the U.S., including large parts of its South; and chunks of Europe. For once, the crisis has nothing to do with energy costs. The emergence of cheap shale gas in the U.S., and the identification of exploitable...

Unlike fossil fuels or precious metals, phosphorus has no alternatives — we (and all other life forms on the planet) need phosphorus; it’s in our DNA, our bones and our energy-producing chemicals (ATP). We get it from our food — meat, grains and vegetables — so it’s not surprising that phosphorus is a key ingredient in fertilizer, as well as a component of sewage, manure and...

Non-chemical water treatment methods generally utilize electricity to prevent scale formation, mitigate corrosion and control microbial growth. When properly applied, non-chemical water-treatment technologies help plants reduce chemical consumption, minimize waste and possibly save water and energy. The following descriptions outline several types of non-chemical water-treatment methods. Magnetic fields...

I drink tap water! There, I finally said it. I am out of the closet — the water closet. My two sons are now cowering with shame, wondering how they can possibly ever face their Dasani-drinking friends again. It was maybe 20 years ago when I first encountered the concept of bottled water. What a strange idea! Why would anybody want to pay for something that’s free — and everywhere —...

Leading up to this month’s 2012 U.S. Presidential election, the legislative landscape has been relatively uneventful. On top of their preoccupation with the election campaigns, lawmakers on both sides of the political spectrum have been reluctant to pin their agendas to any bill that might significantly alienate large groups of voters. Nevertheless, two relatively significant changes are coming down...

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...
