The project team consists of researchers from three leading mining schools, Virginia Tech, Indian School of Mines, and the University of Kentucky; the process equipment manufacturer Eriez Manufacturing; Taggart Global, an architecture and engineering firm specializing in coal plant design and construction; Indian coal producer Auroma Coke Limited (ACL); Sharpe International, which has expertise in building and operating coal plants in India; and Leonardo Technologies, which is experienced in assessing the impacts of various coal technologies on controlling greenhouse gas emissions.
One of the processes has already been tested successfully in the U.S. at pilot scale under the sponsorship of the U.S. Department of Energy (DOE). While the process is highly efficient in cleaning relatively coarse coals whose particle size is in the range of 80 to 6 mm, its efficiency deteriorates below the lower size limit. Therefore, a new method of dry cleaning finer coal will be explored in the India project. An earlier work also funded by the DOE will be the basis for developing this new process.
The project will promote rapid deployment of the dry beneficiation processes in India. In phase 1, a pilot-scale deshaling unit with a maximum capacity of five tons per hour will be constructed and installed at different mine sites and/or power plants. In phase 2, a detailed flow sheet and engineering diagrams will be developed to construct a full-scale proof-of-concept plant in India. The successful completion of phase 2 will constitute a fully operational and commercially viable installation of the proposed technology in India, said Yoon. This large-scale test work in phase 2 eliminates risks associated with scale-up and allows a proof-of-concept plant to serve as a model for future installations
