Synthesis Gas Demonstration Plant Program, Phase I. Trade-off study report II: gas purification alternatives

Description: Gas purification must be carried out in two stages for economic and technical reasons. The requirements of the first stage can be met by a Rectisol plant by Lotepro/Linde AG, or by a Selexol unit by Air Products/Allied Chemical. The second stage in either case should be a Nitrogen Wash unit. The Rectisol solvent (methanol) is freely available worldwide. Selexol solvent is obtainable only from single sources in the USA and in Germany, but serious supply problems are not anticipated. Selexol solv… more

Vehicle-miles of travel statistics, lifetime vehicle-miles of travel, and current state methods of estimating vehicle-miles of travel

Description: This comprehensive review of current statistics on vehicle-miles of travel (VMT) in the United States identifies and evaluates sources of national VMT data for highway, rail, and air travel. From available information, VMT statistics by form of travel have been compiled for 1974. Vehicle lifetime VMT is estimated separately for passenger cars and trucks. A survey of state practices in estimating VMT shows that states use one of three methods: (1) the fuel consumption method, (2) the traffic cou… more

Near-field interactions

Description: To approach the subject of high level nuclear waste disposal in deep ocean sediments it is convenient to differentiate between processes occurring in a near field environment, that region arbitrarily defined as lying between the canister surface and the maximum extent of the 100/sup 0/C isotherm, and those which occur at lower temperatures and beyond the influence of intense radiation. A variety of considerations related to the chemistry of seawater-sediment mixtures suggests that about 200/sup… more

Carbonate scaling - literature review and analysis

Description: A survey of the literature on carbonate scaling is presented as it affects geothermal fluid systems. The geothermal brine, as the fluid is called, contains a number of chemical constituents which have leached into it from the reservoir rock. As the hot fluid is withdrawn through wells, a flow of steam, water, or a mixture of steam and water, results. If the well flows at a high enough rate, some brine will flash to steam because of the pressure drop, resulting in the steam/water flow mixture. T… more
