Abstract
Method and apparatus for transporting a slurry along a pipeline having a number of downstream delivery points along its length and a plant at each delivery point for burning or otherwise using a part of the solids, such as coal, obtained from the slurry. In the practice of the method, the pipeline is filled with a carrier fluid, such as water, and batches of slurry are introduced between batches of the carrier fluid for movement along the pipeline. Each batch of slurry is separated from the batches of carrier fluid by a cap and a tail, the cap and tail being formed from a liquid suspension of fine solids. At each downstream delivery point, each batch of slurry and its cap and tail are directed out of the pipeline into a holding tank. A portion of the contents of the holding tank is removed from the holding tank and dewatered to produce a large mesh solids cake and a centrate defined as a liquid suspension of fines. The remainder of the contents of the holding tank and a cap and tail formed from the centrate is then directed into the pipeline downstream of the delivery point between the batches of carrier fluid for transit to the next delivery point along the pipeline. The foregoing…
