The following letter originally appeared in Chemical Engineering, December 2011, p. 6. The U.S. Dept. of Health and Human Services’ (HHS) flawed and unwarranted ruling that styrene poses a health hazard continues to stir opposition from respected scientists, manufacturing leaders, the hundreds of thousands of American workers whose jobs depend on a viable styrene industry, and a broad-based...

(From November 2011, Letters) Perhaps enough has been written about the questionable science underlying recent U.S. government pronouncements concerning formaldehyde and human cancer of the lymphohematopoietic system (“LHPs—including the leukemias and the lymphomas)*. Now, suppliers of formaldehyde-containing product must face the uncertainties and high expense of defending questionable and...

Water and steam are vital components of virtually all plants in the chemical process industries (CPI). And, a very important operation is the treatment of makeup water to produce the purity required for certain applications, most notably for use in heat exchangers and steam turbines. An important consideration in water treatment is that many industrial facilities are, or will soon be, dealing with...

One of the biggest issues related to dust collection is compliance with U.S. Occupational Safety Health Administration (OSHA) and U.S. Environmental Protection Agency (EPA) regulations regarding combustible dusts and air quality. And as both agencies up the ante with tighter regulations and more scrutinizing inspections, it is imperative that processors make sure their facilities are meeting the standards...

Yesterday, U.S. District Court judge Paul Friedman denied a legal motion by the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) that would have prevented environmental groups from challenging EPA's stay of proposed changes to the Maximum Achievable Control Technology (MACT) standard for industrial boilers. While the decision was procedural, it suggests to ACC that the stay is...

Steam-assisted, gravity-drainage (SAGD) operations employ large tanks that vent flammable and sometimes toxic gases. Safety and environmental concerns often require engineers to design vapor-recovery units (VRUs) to collect these gases and redirect them to a useful location — frequently for use as a fuel gas in a steam-generation system. When choosing a VRU setup for an SAGD facility, the two most...

For years it has been the common practice to treat process water with various chemistries to prevent scale, corrosion and microbiologicals. However, as regulatory issues tighten, water scarcity becomes a growing concern and the cost of treatment chemicals increases, chemical processors are finding that stringent treatment chemicals are not the only answer. Instead, they’re relying upon a multi-prong...

Almost by definition, chemical engineering is a “green” discipline today, as it so often involves efforts to optimize chemical processes in order to reduce the amount of energy and raw materials that are used and the amount of waste that is generated. Today everybody “talks green” but in a lot of cases engineers are the most qualified people to provide the tools required to make...
