ABSTRACT:
Finely divided coal is slurried with liquid carbon dioxide and pumped from a source (mine, dump, railway car, etc.) to a loading pier where, after deslurrying, the coal is pneumatically carried by gaseous carbon dioxide into a storage facility or directly to a waterborne carrier. The coal is maintained under a blanket of carbon dioxide gas during storage and transport. When the waterborne carrier, which may be an ocean going vessel or an inland waterway vessel, reaches its destination, the coal is removed using carbon dioxide gas and then delivered to storage or a use point. If the use point is some distance away, the coal may be reslurried with liquid carbon dioxide and pumped to its final destination.
