Researchers from the Chinese Academy of Sciences (Beijing, China; www.cas.cn), led by professor Ying-Jie Zhu, have reported a “smart” fire-alarm wallpaper prepared using ultralong hydroxyapatite nanowires and graphene oxide thermosensitive sensors. At room temperature, the graphene-oxide sensor is an electrical…
Using ultraviolet (UV) radiation or ozone (or both) to oxidize air pollutants, such as volatile organic compounds (VOCs) is a well-established treatment method in the chemical process industries (CPI). What is not so well known, however, is that for most…
Professor Toru Murayama at Tokyo Metropolitan University (Tokyo, Japan; www.haruta-masatake.ues.tmu.ac.jp), in collaboration with Chugoku Electric Power Co., Inc., has developed a vanadium oxide catalyst that removes oxides of nitrogen (NOx) from fluegas generated by the combustion of heavy fuel oil…
The world’s first pilot plant for manufacturing bio-based furan dicarboxylic methyl ester (FDME) began operating last month in Decatur, Ill. A collaboration between DuPont Industrial Biosciences (Wilmington, Del.; www.biosciences.dupont.com) and Archer Daniels Midland Co. (ADM; Chicago, Ill.; www.adm.com), the 60-ton/yr…
A remote-operated, screw-propelled (amphirol) machine equipped with a vacuum hose can remove solid catalyst material from reactors robotically, allowing plants to avoid subjecting personnel to enclosed work environments and inert atmospheres. Currently, catalyst changeout requires personnel to work inside process…
Hydrotreating is an important petroleum refining process in which sulfur and other contaminants are removed in the manufacture of transportation fuels. At the recent annual meeting of the American Fuel and Petrochemical Manufacturers (AFPM), Honeywell UOP (Des Plaines, Ill.; www.uop.com)…
A group of researchers from South Dakota School of Mines and Technology (SDSM&T; Rapid City; www.sdsmt.edu) has developed a modular technology known as the Gas Cube, which can convert a wide variety of liquid and solid waste into methane. Having…
Hydrogen sulfide occurs naturally in petroleum reservoirs, but must be removed from crude oil prior to transportation from drilling sites to storage tanks at petroleum refineries. H2S is corrosive to storage tanks, pipelines and railcars, and without proper treatment, can…
The global textile industry generates a great deal of waste, and many efforts are taking place to make textile processing more sustainable. PolyOne Corp. (Cleveland, Ohio; www.polyone.com) has introduced a new fiber-colorant technology for polyester that incorporates proprietary high-pressure metering…
