POC-scale testing of an advanced equipment/technology. Quarterly technical progress report No. 1, October--December 1994

The main objective of the proposed program is to evaluate a novel surface modification technique, which utilizes the synergistic effect of metal ions-surfactant combination, for dewatering of ultra-fine clean coal on a proof-of-concept scale of 1 to 2 tph. The novel surface modification technique developed at the University of Kentucky Center for Applied Energy Research (UKCAER) will be evaluated using vacuum, centrifuge, and hyperbaric filtration systems. Dewatering tests will be conducted using the fine clean coal froth produced by the column flotation units at the Powell Mountain Coal Company, Mayflower Preparation Plant in St. Charles, Virginia. The POC-scale studies will be conducted on two different types of clean coal, namely, high sulfur and low sulfur clean coal. The Mayflower Plant processes coals from five different seams, thus the dewatering studies results could be generalized for most of the bituminous coals. The project team met with the DOE project management representatives at the Pittsburgh Energy Technology Center on November 18, 1994 to review project plans. After review and comments provided by the DOE, the Project Management and Work Plans were issued on December 15, 1994. The project team held a meeting at the Powell Mountain Coal Company Mayflower Preparation Plant to discuss the strategy on installation and operation of the various dewatering units. Samples of the low sulfur and high sulfur clean coal froths were collected and shipped to UKCAER and Andritz Ruthner Inc.
