INTEGRATED DRILLING SYSTEM USING MUD ACTUATED DOWN HOLE HAMMER AS PRIMARY ENGINE
A history and project summary of the development of an integrated drilling system using a mud-actuated down-hole hammer as its primary engine are given. The summary includes... -
Economic evaluation of the modified TRW Gravichem process: one unit train...
The TRW Gravichem process, a chemical desulfurization process to remove sulfur from coal, has been modified and evaluated by the Process Evaluation Office of the Department of... -
On the constitutive relation for frictional flow of granular materials:...
The flow of granular materials is an economically important phenomenon which is poorly understood. Granular materials may flow in several regimes: gas-solid two phase flow,... -
Ground movements associated with gas hydrate production. Progress report,...
The grantee will evaluate the influence of hydrate production on ground subsidence near the wellbore and the surface. The objective of this research will be achieved by using... -
Preparation and analyses of low-rank coals for combustion applications....
The micronized slurry fuel was prepared by grinding the clean float coal with water in two stages. The first stage was a conventional 4-ft diameter overflow mill charged with a... -
Surface adhesion of low-rank coal ash. Quarterly technical progress report,...
The percentage of ion-exchangeable cations was determined for the Center lignite. The ion-exchanged material was produced by treating the lignite with ammonium acetate which... -
Acid mine drainage potential of raw, retorted, and combusted Eastern oil...
In order to manage the oxidation of pyritic materials effectively, it is necessary to understand the chemistry of both the waste and its disposal environment. The objective of... -
Economic evaluation of losses to electric power utilities caused by ash...
Problems with convection ash fouling and wall slagging were considerable during our study. The Dakota lignites posed the greatest problems, particularly with fouling. The... -
Evaluation of mechanistic models for coal gasification. Final technical...
In the past US Department of Energy had sponsored projects for development of detailed mathematical models of gasification reactors. Four different mechanistic models were... -
Utility advanced turbine systems (ATS) technology readiness testing and...
The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the US Department of Energy (DOE) is the development of the GE 7H and 9H... -
