Nitrogen oxide stack sampling at the U.S. DOE Oak Ridge Y-12 Steam Plant
On November 7, 1997, the EPA proposed a Nitrogen Oxides State Implementation Plan Call (NO{sub x} SIP Call) for 22 states in the Eastern US which included the state of Tennessee. This initial proposal was followed by proposed statewide NO{sub x} budgets in the May 11, 1998, Supplemental Notice of Proposed Rulemaking. In the development of the NO{sub x} SIP Call, EPA performed a number of air quality analyses and determined that NO{sub x} emissions from Tennessee should be reduced. Industrial boilers, turbines, stationary internal combustion engines, and cement manufacturing are the only non-electric generating unit sources for which reductions are assumed in the budget calculation. Emission reductions are required if specific source heat input capacity is greater than 250 million Btu per hour. The US Department of Energy (DOE) Oak Ridge Y-12 Steam Plant consists of four Wickes pulverized coal fired boilers each rated at a maximum heat input capacity of 298 million Btu per hour, and will therefore be impacted by these regulatory actions. Each boiler is equipped with two pulverizing mills. Coal or natural gas or a combination of these two fuels may be fired. This paper provides the results of NO{sub x} emission stack testing conducted …

A NOVEL CO{sub 2} SEPARATION SYSTEM
Because of concern over global climate change, new systems are needed that produce electricity from fossil fuels and emit less CO{sub 2}. The fundamental problem with current systems which recover and concentrate CO{sub 2} from flue gases is the need to separate dilute CO{sub 2} and pressurize it to roughly 35 atm for storage or sequestration. This is an energy intensive process that can reduce plant efficiency by 9-37% and double the cost of electricity. There are two fundamental reasons for the current high costs of power consumption, CO{sub 2} removal, and concentration systems: (1) most disposal, storage and sequestering systems require high pressure CO{sub 2} (at roughly 35 atm). Thus, assuming 90% removal of the CO{sub 2} from a typical atmospheric pressure flue gas that contains 10% CO{sub 2}, the CO{sub 2} is essentially being compressed from 0.01 atm to 35 atm (a pressure ratio of 3,500). This is a very energy intensive process. (2) The absorption-based (amine) separation processes that are used to remove the CO{sub 2} from the flue gas and compress it to 1 atm consume approximately 10 times as much energy as the theoretical work of compression because they are heat driven cycles working over …

A Novel Synthesis of Polyesters Containing Hexa-(tert-butylhydroquinone)cyclotriphosphazene
The majority of polyphosphazene material research has concentrated on the linear polymer configuration. However, this represents only one of three potential backbone configurations for phosphazenes. Linear polymers are formed either directly from phosphorus and nitrogen containing precursors or from the ring opening polymerization of hexachlorocyclotriphosphazene. Two other backbone structures can be formed from hexachlorocyclotriphosphazene cyclolinear and cyclomatrix. Cyclolinear are the least studied due to synthetic difficulty. Cyclomatrix polymers represent a more facile method for forming non-linear phosphazenes.
