After 8 years of extensive R and D in the new technology of coal log pipeline (CLP), a pilot plant is being built to demonstrate and test a complete CLP system for coal transportation. The system consists of a coal log fabrication plant, a 3,000-ft-length, 6-inch-diameter underground pipeline loop to transport 5.4-inch diameter coal logs, a log injection/ejection system, a pump bypass, a reservoir that serves as both the intake and the outlet of the CLP systems, an instrumentation system that includes pressure transducers, coal log sensors, and flowmeters, and an automatic control system that includes PLCs and a central computer. The pilot plant is to be completed in May of Year 2000. Upon completion of construction, the pilot plant will be used for running various types of coal, testing the degradation rate of drag reduction in CLP using Polyox (polyethylene oxide), testing the reliability of a special coal log sensor invented at the University of Missouri, testing the reliability and the efficiency of the pump-bypass system for pumping coal log trains through the pipe, and testing various hardware components and software for operating the pilot plant. Data collected from the tests will be used for designing future commercial systems of CLP. The pilot plant experiments are to be completed in two years. Then, the technology of CLP will be ready for commercial use.
