Pierce Transit's Experience with an Alternate Fuel Compressed Natural Gas January-December 1992
At the end of 1992, Pierce Transit's CNG fleet consisted of 30, 40-foot Orion buses, 19 ElDorado Buses, on GMC 'New Look' bus, one 1990 Chevy Celebrity, and one Collins Shuttle van. As...
Cleaning Up in the Former Soviet Union
As they negotiate with authorities in Russia, Azerbaijan, Kazakhstan and other former Soviet Republics, Western companies�including many of the big oil and natural-resources firms�are...
Letter from Oman
The bonanza days of the 1980s are over, but the oil-rich sultanate continues to be a rewarding, if challenging, market. Oil remains a focus of investment, and the government is planning...
Influence of Gas Phase Turbulence on the Transport of Particles
An interesting and perhaps unexpected flow feature characterizing the transport of a gas-solid suspension in a vertical duct is the radial nonuniformity of particles over the tube cross-section....
Hydrogen Reduction of Lunar Soil and Simulants
Carbotek, Inc., and the Energy and Environmental Research Center (EERC) are cooperating on further development of the Carbotek process to produce oxygen from lunar ilmenite by hydrogen...
Lunar Oxygen ? The Reduction of Glass by Hydrogen
The direct reduction of volcanic glass by hydrogen has been proposed as a method of extracting oxygen from the lunar soil. Experiments using lunar simulant glasses reacted with flowing...
A Modified Sulfate Process to Lunar Oxygen
A modified sulfate process which produces oxygen from iron oxide-bearing minerals in lunar soil is under development. Reaction rates of ilmenite in varying strength sulfuric acid have...
Steady State Composition with Low Fe?+ Concentrations for Efficient O2 Production by Magma Electrolysis of Lunar Soils
Parameters are estimated for a hypothetical, well stirred, continuous-feed electrolytic cell that converts 20% of a lunar soil feedstock to O2 gas,...
Better Cover-Ups
Designing the final cover for a solid waste landfill or remediation site is often trickier than designing its lining because a cover will undergo more unpredictable stress and distress...
Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...
Feasibility Study of Petroleum Development in the Ross Sea, Antarctica
This paper discusses the viability of Antarctic petroleum development and estimates when Antarctic oil production could become economically feasible. The analysis is based on a hypothetical...
Offshore Challenge
Standard design techniques weren't enough to create rigs for the Main Pass Mine, which, at 67 million long tons, is the largest offshore sulfur mine in U.S. history. The 18...
Effects of Natural Gas Storage on Gas Price Forecasts
This paper explores the effects of natural gas storage on short-term gas price forecasts. At the Southern California Edison Company (Edison), the gas price forecast incorporates a multitude...
The Future of Non-Utility Generation
The business of designing, constructing and operating non-utility owned electric power plants continues to evolve into the 1990s. The industry is consolidating as smaller market participants...
Exclusion of Foreign Materials from the Savannah River Site (SRS) Canistered Waste Forms: Characterization of the Gas within the Free Volume
Glass-filled canisters, produced at the SRS Defense Waste Processing facility, must meet the Waste Acceptance Preliminary Specifications (WAPS) developed by DOE's Office of...
Effect of a Low-Permeability Layer on Calculated Gas Flow at Yucca Mountain
Yucca Mountain is being studied to determine its suitability as a location for a high-level nuclear waste repository. The mountain is a steep-sided linear ridge which is underlain by a...
Status of WIPP Compliance with EPA 40 CFR 191, December 1990?SAND90-2424C
Sandia National Laboratories is conducting performance assessments for the United States Department of Energy to use in evaluating compliance of the Waste Isolation Pilot Plant with EPA...
A G.I.S. for Cross Country Pipelines
Faced with an increased workload, greater information demands and a limited staff, the Civil Engineering Section of Columbia Gas Transmission is trying a different approach to the selection...
Infrared Thermography Based Pipeline Leak Detection
Computerized Infrared Thermographic pipeline inspection is now a refined and reliable process having been thoroughly proven to be an accurate, cost effective, and efficient technology...
Gas Phase Turbulence Modification with Fine Particles in 2-D Duct Flow
The effect of a dilute suspension of fine particles on a two-dimensional turbulent duct gas flow is measured with hot-film anemometry. The flow field without particles is compared to the...
