Adsorption and absorption play a big role in reducing air pollution in many applications around the world. Studies show that the largest single use of absorbers this year will be to capture SO2 from power-plant flue gas. Adsorbers will be used by many chemical process industries (CPI) to capture volatile organic compounds (VOCs) and odors. A small, but fast growing industrial segment uses ozone and...

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...

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...
