Reducing freshwater consumption and wastewater discharge at large petroleum-refining and chemical-production facilities can lower costs, while allowing plants to expand production capacities without having to secure additional freshwater resources and without having to enlarge their wastewater treatment plants. The key approaches to saving significant amounts of water are: improved water management...

Already, in the first two months of this year, the unpredictable and winding road of the so-called Boiler MACT, has taken yet another set of hair-pinned curves. Now industry groups are pushing even harder for an act of Congress that would put on the brakes and allow more time for the regulations to be reshaped. At stake, says Robert Bessette, president of the Council of Industrial Boiler Owners (CIBO...

Production of natural gas from shale formations presents key water management challenges. As the number of gas drilling operations continues to grow in shale plays around the world, and the practice of hydraulic fracturing (frac or fracing) of gas wells remains widespread, efficient water use strategies are becoming critical aspects of shale gas operations. Fresh water supplies for drilling and fracturing...

(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...

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...

Last year, the U.S. Environmental Protection Agency (EPA;Washington, D.C.; www.epa.gov) proposed new emissions standards for hazardous air pollutants (HAP) emitted by industrial boilers and solid-waste incinerators (CISWI) based on the performance of the maximum achievable control technology (MACT). The so-called “boiler MACT” final rules were signed by the EPA Administrator on February 21...
