This company delivers turnkey thermal utilization plants for these and other production facilities that... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/10488.html Wed, 1 May 2013 0:00:00 EDT Praxair, Inc. (Danbury, Conn.; www.praxair.com) and Valero have successfully implemented Praxair’s new CONOx emissions-control technology at Valero’s petroleum refinery in Ardmore, Oklahoma. This technology has helped the refinery meet its fluid-catalytic cracking (FCC) unit oxides-of-nitrogen... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/10440.html Fri, 19 Apr 2013 0:00:00 EDT  Figure 1. A handful of ceramic proppants is shown here Carbo Ceramics This article covers permitting and directly related design issues associated with thermal processes using drying and calcining for the production of both proppant sand and ceramic proppants (Figure 1) as an illustrative example (see... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/10180.html Fri, 1 Feb 2013 0:00:00 EST 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... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/9782.html Tue, 2 Oct 2012 0:00:00 EDT 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 oxidants in combination with absorbers.... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/9251.html Tue, 1 May 2012 0:00:00 EDT The Babcock & Wilcox Co. (B&W; Charlotte, N.C.; www.babcock.com) says that its subsidiary, Babcock & Wilcox Power Generation Group, Inc. (B&W PGG), has been awarded a contract to design and... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/8994.html Sat, 4 Feb 2012 0:00:00 EST U.S. Environmental Protection Agency (EPA) regulations call for continuous emissions monitoring (CEM) systems to be tested with “zero-air” materials to qualify the accuracy of the instruments. CEMS operators sometimes mistakenly use a... http://www.che.com/environmental_health_and_safety/environmental_mgmt/air_pollution_control/8964.html Wed, 1 Feb 2012 0:00:00 EST The Babcock & Wilcox Co.
