Process configurations/modeling -- Project 3.1. Final report, September 1, 1992--November 30, 1993

Description: The objective of this research is to develop and optimize preliminary process designs and cost estimates for a moving bed granular limestone desulfurization process typified by the LEC (Limestone Emission Control) process. The basic simulation programs have been written, debugged, and used to simulate the operation of a desulfurization plant with a cross flow moving bed configuration. The programs are based on first principles type mathematical models which reflect the underlying transport and … more

AFBC-HAGT, an efficient small scale power plant

Description: A team comprised of the Energy and Environmental Research Corporation (EER), the Will-Burt Company, and the Ohio Agricultural Research and Development Center (OARDC) designed installed and tested a pilot scale atmospheric fluidized (bubbling) bed combustion (AFBC) system to heat hot water. Following testing, a commercial prototype unit was installed at Cedar Lane Farms (CLF), near Wooster, Ohio. The unit was started up in January, 1995, and is currently in operation. It provides hot water for g… more

Production of Elemental Sulfur From Spent Sorbent and CO{sub 2}. Final Report, April 1, 1992--October 31, 1994

Description: This proof of concept project studied the feasibility of producing elemental sulfur from a spent solid sorbent and carbon dioxide (CO{sub 2}) gas. The objectives were to research (1) producing H{sub 2}S gas from an aqueous solution produced from spent sorbent solid consisting of primarily CaS, and (2) research the potential of producing elemental sulfur at temperatures below 600{degrees}C by means of a novel reaction between H{sub 2}S with CO{sub 2}. The spent sorbent derives from a novel coal … more

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation. Quarterly Technical Progress Report No. 12, July 1, 1991--September 30, 1991

Description: 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 p… more

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation. Quarterly Technical Progress Report No. 14, January 1, 1992--March 31, 1992

Description: In order to develop additional confidence in the conceptual design of the advanced froth flotation circuit, a 2-3 TPH Proof-of-Concept (POC) facility was necessary. During operation of this facility, the ICF KE team will demonstrate the ability of the conceptual flowsheets to meet the program goals of maximum pyritic sulfur reduction coupled with maximum energy recovery on three DOE specified coals. The POC circuit was designed to be integrated into the Ohio Coal Development`s facility near Bev… more

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation. Quarterly Technical Progress Report No. 16, July 1, 1992--September 30, 1992

Description: A study conducted by Pittsburgh Energy Technology Center of sulfur emissions from about 1,300 United States coal-fired utility boilers indicated that half of the emissions were the result of burning coals having greater than 1.2 pounds of SO{sub 2} per million BTU. This was mainly attributed to the high pyritic sulfur content of the boiler fuel. A significant reduction in SO{sub 2} emissions could be accomplished by removing the pyrite from the coals by advanced physical fine coal cleaning. An … more

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation. Quarterly Technical Progress Report No. 17, August 1, 1992--December 31, 1992

Description: The construction of the DOE POC at the OCDO facility continued through this entire quarter. By the end of the quarter approximately 90% of all of the construction had been completed. All equipment has beeninstalled, checked for mechanical and installation and operated from a local pushbutton. During this quarter a review of items to be completed for start-up was compiled. This information was then presented to the construction subcontractors and agreement was concluded that all items will be co… more
