Development, testing, and demonstration of an optimal fine coal cleaning circuit. Task 5: Evaluation of bench-scale test results and equipment selection for in-plant pilot tests
Abstract
The overall objective of this research effort is to improve the efficiency of fine coal flotation in preparation plants above that of currently used conventional cells. In addition to evaluating single-stage operation of four selected advanced flotation devices, the project will also evaluate them in two-stage configurations. The project is being implemented in two phases. Phase 1 comprises bench-scale testing of the flotation units, and Phase 2 comprises in-plant, proof-of-concept (POC), pilot-scale testing of selected configurations at the Cyprus Emerald preparation plant. The Task 5 report presents the findings of the Phase 1 bench-scale test results and provides the basis for equipment selection for Phase 2. Four advanced flotation technologies selected for bench-scale testing are: Jameson cell; Outokumpu HG tank cell; packed column; and open column. In addition to testing all four of the cells in single-stage operation, the Jameson and Outokumpu cells were tested as candidate first-stage cells because of their propensity for rapid attachment of coal particles with air bubbles and low capital and operating costs. The column cells were selected as candidate second-stage cells because of their high-efficiency separation of low-ash products from high-ash feed coals. 32 figs., 72 tabs.

This document is the third interim report on tests that were conducted at the Duct Injection Test Facility (DITF) operated for the Department of Energy at Unit 5 of the Ohio Power Company's Muskingum River station in Beverly, Ohio. At the DITF dry calcium hydroxide (Ca(OH)2), an aqueous slurry of Ca(OH)[sub 2] (prepared by slaking quicklime), or a mixture of one of these sorbents with waste ash from earlier tests was injected into a slipstream of flue gas from the Unit 5 boiler to achieve partial removal of SO[sub 2] in the flue gas.

DEVELOPMENT, TESTING, AND DEMONSTRATION OF AN OPTIMAL FINE COAL CLEANING CIRCUIT
The objective of this project was to improve the efficiency of the fine coal froth flotation circuit in commercial coal preparation plants. The plant selected for this project, Cyprus Emerald Coal Preparation Plant, cleans 1200-1400 tph of Pittsburgh seam raw coal and uses conventional flotation cells to clean the minus 100-mesh size fraction. The amount of coal in this size fraction is approximately 80 tph with an average ash content of 35%. The project was carried out in two phases. In Phase I, four advanced flotation cells, i.e., a Jameson cell, an Outokumpu HG tank cell, an open column, andmore » -

Laboratory program to support H-Coal Pilot Plant operations: bench-scale tests on Kentucky No. 11 coal. [Kentucky No. 11 coal evaluation]
Hydrocarbon Research, Inc., conducted a bench-scale program to evaluate Kentucky No. 11 coal in the H-Coal system. The test used standard operating conditions, and performance was judged against that of Illinois No. 6 coal which has been used in other H-Coal studies. The H-Coal process operations with Kentucky No. 11 coal are similar to those with Illinois No. 6 coal feed. However, due to the physical property differences of the recycle oil, an adjustment in feed composition and/or temperature appears to be required for sustained coal feeding. The Kentucky No. 11 coal gave about 1.5 W % higher coal conversionmore »
