Integrated dry NO sub x /SO sub 2 emissions control system (open access)

Integrated dry NO sub x /SO sub 2 emissions control system

This project's goal is to demonstrate the removal up to 70% of the NO{sub x} and 70% of the SO{sub 2} emissions from coal fired utility boilers. It will establish an alternative emissions control technology integrating a combination of several processes, while minimizing capital expenditures and limiting waste production to dry solids that are handled with conventional ash removal equipment. These processes include low-NO{sub x} burners, NO{sub x} ports and urea injection for NO{sub x} control, sodium or calcium based sorbent injection for SO{sub 2} control, and flue gas humidification to enhance the reactivity of the SO{sub 2} control compound.

Safety questions relevant to nuclear thermal propulsion (open access)

Safety questions relevant to nuclear thermal propulsion

Nuclear propulsion is necessary for successful Mars exploration to enhance crew safety and reduce mission costs. Safety concerns are considered by some to be an implements to the use of nuclear thermal rockets for these missions. Therefore, an assessment was made of the various types of possible accident conditions that might occur and whether design or operational solutions exist. With the previous work on the NERVA nuclear rocket, most of the issues have been addressed in some detail. Thus, a large data base exist to use in an agreement. The assessment includes evaluating both ground, launch, space operations and disposal conditions. The conclusion is that design and operational solutions do exist for the safe use of nuclear thermal rockets and that both the environment and crews be protected against harmful radiation. Further, it is concluded that the use of nuclear thermal propulsion will reduce the radiation and mission risks to the Mars crews.

Space nuclear power requirements for ozone layer modification (open access)

Space nuclear power requirements for ozone layer modification

This work estimates the power requirements for using photochemical processes driven by space nuclear power to counteract the Earth's ozone layer depletion. The total quantity of ozone (O{sub 3}) in the Earth's atmosphere is estimated to be about 4.7 {times} 10{sup 37} molecules. The ozone production and destruction rates in the stratosphere are both on the order of 4.9 {times} 10{sup 31} molecules/s, differing by a small fraction so that the net depletion rate is about 0.16 to 0.26% per year. The delivered optical power requirement for offsetting this depletion is estimated to be on the order of 3 GW. If the power were produced by satellite reactors at 800 km altitude (orbit decay time {approximately} 300 years), some means of efficient power beaming would be needed to deliver the power to stratospheric levels (10--50 km). Ultraviolet radiation at 140--150 nm could have higher absorption rates in O{sub 2} (leading to production of atomic oxygen, which can combine with O{sub 2} to form O{sub 3}) than in ozone (leading to photodissociation of O{sub 3}). Potential radiation sources include H{sub 2} lasers and direct nuclear pumping of ultraviolet fluorescers. 5 refs.

(Particulate Flow Research Lab) quarterly progress report, July 1, 1991--September 30, 1991 (open access)

(Particulate Flow Research Lab) quarterly progress report, July 1, 1991--September 30, 1991

Research at the Particulate Flow Research Lab continued. In the previous report it was mentioned that an anticipated change in the sphere diameter necessitated a resizing of the chute components. A check has indicated that the increased size has added enough weight to require a re-evaluation of the stresses requiring stronger fasteners. Mathematical formalism is given for the chip radiation model, and signal processing of the radiation received from the transmitting chips has been improved. A prototype apparatus has been designed and built in order to collide two identical spheres at a point in space. 4 figs.

Synthesis of octane enhancers during slurry-phase Fischer-Tropsch (open access)

Synthesis of octane enhancers during slurry-phase Fischer-Tropsch

The objective of this project is to investigate three possible routes to the formation of ethers, in particular methyl tert-butytl ether (MTBE), during slurry phase Fischer-Tropsch reaction. The three reaction schemes to be investigated are: (1) Addition of isobutylene during the formation of methanol and/or higher alcohols directly from CO and H{sub 2} during slurry-phase Fischer-Tropsch; (2) addition of isobutylene to FT liquid products including alcohols in a slurry-phase reactor containing an MTBE or other acid catalyst; and, (3) addition of methanol to slurry phase FT synthesis making iso-olefins.

Hydrocarbons associated with brines from geopressured wells. Third quarterly technical progress report, 1 July 1991--30 September 1991

Efforts to determine the concentration of the cryocondensates in fluids of the various USDOE Geopressured wells a function of production volume. The wells are visited monthly as they are operating and samples are reported taken cryogenically during each visit. A gas scrubbing system continuously sample the gas streams of the wells in the intergas scrubbing system continuously sample the gas streams of the wells in the intervals between visit. Results obtained are to correlated the production of the collected compounds with reservoir and well production characteristics.
