Last month, the first pilot project that used chilled ammonia to capture carbon dioxide from the fluegas (FG) of a coal-fired power plant started operating at the 1,210-MW We Energies’ Pleasant Prairie power plant in Wisconsin. Alstom (Windsor, Conn.; edlinks.chemengonline.com/7371-531)…
Advanced Diamond Technologies, Inc. (ADT; Romeoville, Ill.; edlinks.chemengonline.com/7371-533) has launched a new family of mechanical seals to improve efficiency, save energy and reduce costs in fluid-pumping systems. The patented UNCD (ultrananocrystalline diamond) Seals provide the benefits of a diamond at…
Of all known materials, carbon nanotubes (CNTs) have the highest thermal conductivity and mechanical strength as well as the ability to withstand the highest electric-current density, making them an attractive material for electric wiring, heat dissipation, field electron emission, and…
In its first full-scale test on a coal-fired power plant, halogenated activated carbon (AC) made by ADA-ES, Inc. (Littleton, Colo.; edlinks.chemengonline.com/7371-537) has reduced mercury emissions by more than 90%. The significance of the results is that the plant burns western…
Nippon Steel Materials Co., Ltd. (NSM; Tokyo, Japan; edlinks.chemengonline.com/7371-538) has developed a new catalyst for combustion engines that contains 70% less precious metals than conventional catalytic converters. The catalyst is expected to not only lead to lower costs, but also…
The Seebeck effect — the direct conversion of a temperature difference to electricity — is responsible for the operation of thermocouples. But taking advantage of this phenomenon to make electricity from waste heat in so-called thermoelectric (TE) devices has been…
The standard way to test for toxicity in individuals who have been exposed to heavy metals is to take a blood sample and analyze it in the laboratory by plasma mass spectrometry, an expensive and time-consuming procedure. Now, a portable…
Although nanoporous silica membranes are promising systems for the molecular separation of gases and liquids, they lack microstructural stability in the presence of water at temperatures as low as 60°C. Prolonged exposure to water causes hydrolysis, resulting in the formation…
Ateam of researchers at the U.S. Department of Energy’s Argonne National Laboratory (ANL, Argonne, Ill.; edlinks.chemengonline.com/7370-568) has developed a membrane capable of producing olefins from alkanes, and reducing wasted energy and pollutants while improving selectivity and yield. Steam cracking, or…
Flowserve Corp. (Dallas, Tex.; edlinks.chemengonline.com/7370-569) has introduced a new noise-attenuating valve-trim for gaseous applications, one that simultaneously lowers the device’s manufacturing costs while improving its noise reduction capabilities. Like prior noise-attenuation trim, Flowserve’s Valtek Stealth is designed to reduce the…
