Development of the chemical and electrochemical coal cleaning process (open access)

Development of the chemical and electrochemical coal cleaning process

Liberation studies on the Elkhorn No. 3 coal were completed in this quarter. The results obtained from the 65 {times} 150 mesh samples showed that the amount of mineral matter and pyrite liberated by the Chemical and Electrochemical Coal Cleaning (CECC) process increases with time. The free mineral matter undergoes some reduction in size during the CECC treatment and the majority of the liberated mineral particles in this sample are finer than 150 mesh. This is opposite that found for the Pittsburgh No. 8 coal, which may explain the better response of the Elkhorn No. 3 coal to CECC treatment. The continuous bench-scale unit was modified during the quarter to satisfy the health and safety requirements of the university. The unit was modified to ensure that any spill or leakage can be contained. Due to these modifications, continuous testing work was delayed.

Partial-wave analyses of hadron scattering below 2 GeV (open access)

Partial-wave analyses of hadron scattering below 2 GeV

The Center for Analysis of Particle Scattering (CAPS) in the Department of Physics at Virginia Polytechnic Institute and State University has analyzed basic two-body hadron reactions below 2 GeV for the last two decades. Reactions studied were nucleon-nucleon, pion-nucleon, K{sup +}-nucleon and pion photoproduction systems. In addition to analyses of these systems, a computer graphics system (SAID) has been developed and disseminated to over 250 research institutions using VAX computers. The computer-interactive system for disseminating information on basic scattering reactions is also accessible to the physics community through TELNET on the VPI SU physics department VAX. 6 refs.

Development of the chemical and electrochemical coal cleaning process

Studies concerning the use of flotation as an alternative method of separating liberated mineral matter from chemical/electrochemical coal cleaning (CECC) treated coal were continued using Elkhorn No. 3 coal. The results obtained using different methods of recovering the clean product after CECC treatment showed trends similar to those observed previously with Pittsburgh No. 8 coal. The use of flotation after CECC treatment of the Elkhorn No. 3 coal was found to be more efficient than wet-screening. Construction of the continuous bench-scale unit was completed in this quarter. The unit was modified to process 2 lbs/hr instead of the original design of 1 lb/hr so as to ensure efficient operation of the vacuum filter unit. Start-up of the continuous unit was successfully conducted and shakedown testings were started. Initial results show that the continuous unit was able to reduce the ash content of a recently acquired Wyodak coal sample to as low as 1.16%. 2 tabs.

Development of the chemical and electrochemical coal cleaning process

The continuous testing of the Chemical and Electrochemical Coal Cleaning (CECC) bench-scale unit (Task 6) was completed successfully in this quarter using Middle Wyodak and Elkhorn No. 3 coal samples. The CECC unit was run under the optimum conditions established for these coal samples in Task 4. For the Middle Wyodak coal, the ash content was reduced from 6.96% to as low 1.61%, corresponding to an ash rejection (by weight) of about 83%. The ash and sulfur contents of the Elkhorn No. 3 coal were reduced to as low as 1.8% and 0.9%. The average ash and sulfur rejections were calculated to be around 84% and 47%. The CECC continuous unit was used to treat -325 mesh Elkhorn No. 3 coal samples and gave ash and sulfur rejection values of as high as 77% and 66%. In these test, the clean -325 mesh coal particles were separated from the liberated mineral matter through microbubble column flotation, instead of wet-screening.

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation

This document a quarterly report prepared in accordance with the project reporting requirements covering the period from July 1, 1992 to September 30, 1992. This report provides a summary of the technical work undertaken during this period, highlighting the major results. A brief description of the work done prior to this quarter is provided in this report under the task headings. The overall project scope of the engineering development project is to conceptually develop a commercial flowsheet to maximize pyritic sulfur reduction at practical energy recovery values. This is being accomplished by utilizing the basic research data on the surface properties of coal, mineral matter and pyrite obtained from the Coal Surface Control for Advanced Fine Coal Flotation Project, to develop this conceptual flowsheet. The conceptual flowsheet must be examined to identify critical areas that need additional design data. This data will then be developed using batch and semi-continuous bench scale testing. In addition to actual bench scale testing, other unit operations from other industries processing fine material will be reviewed for potential application and incorporated into the design if appropriate. The conceptual flowsheet will be revised based on the results of the bench scale testing and areas will be …

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation

The design criteria for each unit operation have been developed based upon a number of variables. These variables, at this time, are based upon the best engineering design information available to industry. A number of assumptions utilized in the design criteria are uncertain. The uncertainties of inert atmospheres for grinding and flotation as well as pyrite depressants were answered by the Surface Control Project. It was determined that inerting was not required and no new'' reagents were presented that improved the flotation results. In addition, Tasks 5 and 6 results indicated the required reagent dosage for conventional flotation and advanced flotation. Task 5 results also indicated the need for a clean coal,thickener, the flocculent dosages for both the clean coal and refuse thickeners, and final dewatering requirements. The results from Tasks 5 and 6 and summarized in Task 7 indicate several uncertainties that require continuous long duration testing. The first is the possibility of producing a grab product for both the Pittsburgh and Illinois No. 6 coals in conventional flotation. Second what does long-term recirculation of clarified water do to the product quality The verification process and real data obtained from Tasks 5 and 6 greatly reduced the capital and …

A program to develop the domestic natural gas industry in Indonesia: Case history of two World Bank projects (open access)

A program to develop the domestic natural gas industry in Indonesia: Case history of two World Bank projects

Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. Technical assistance will be provided …

Development of novel copper-based sorbents for hot-gas cleanup (open access)

Development of novel copper-based sorbents for hot-gas cleanup

The objective of this investigation is to evaluate several novel copper-based binary oxides for their suitability as regenerable sorbents for hot gas cleanup application in the temperature range of 650{degree} to 850{degree}C (1200{degree}--1550{degree}F). To achieve this objective, several novel copper-based binary oxide sorbents will be prepared. Experimental tests will be conducted at ambient pressure to determine the stability, sulfidation capacity, regenerability, and sulfidation kinetics of the novel sorbents. Tests will also be conducted at high pressure for the determination of the sulfidation reactivity, regenerability, and durability of the sorbents. The attrition characteristics of the sorbents will also be determined.

Design-for-analysis or the unintended role of analysis in the design of piping systems

The paper discusses the evolution of piping design in the nuclear industry with its increasing reliance on dynamic analysis. While it is well recognized that the practice has evolved from design-by- rule '' to design-by-analysis,'' examples are provided of cases where the choice of analysis technique has determined the hardware configuration, which could be called design-for-analysis.'' The paper presents practical solutions to some of these cases and summarizes the important recent industry and regulatory developments which, if successful, will reverse the trend towards design-for-analysis.'' 14 refs.

Human resource needs and development for the gas industry of the future (open access)

Human resource needs and development for the gas industry of the future

The natural gas industry will confront many challenges in the 1990s and beyond, one of which is the development of human resources to meet future needs. An efficient, trained work force in this era of environmental concern, high technology, and alternative fuels is essential for the industry to continue to meet the competition and to safely deliver our product and service to all customers. Unfortunately, during this period there will be an increasing shortfall of technical personnel to replace those lost to attrition and a steady decline in the availability of new employees who are able to read, write, and perform simple math. Technological and government developments that will impact the industry and the skill levels needed by the industry employees are reviewed. In-house and external training of professional and nonprofessional personnel and the benefits and disadvantages of selected advanced training methods are discussed. Recommendations are presented that can help improve the training of gas industry employees to meet future needs. 22 refs.
