coal slurry pipeline criteria

Slurry pipeline - Wikipedia

A slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances. A mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out. Due to the abrasive properties of slurry, the pipelines can be lined with high-density polyethylene (HDPE), or manufactured completely from HDPE Pipe, although this requires a very thick pipe wall. Slurry pipelines are used as an alternative to railroad tran

Coal slurry - Wikipedia

To transform the coal ash into a slurry, coal is separated from non-combustable components and can be fractionated by particle size as well. Coal slurry can be transferred by pipeline or with specialized pumps such as a progressive cavity pumpto pump the highly abrasive, corrosive and viscous coal slurry. More than 7 billion tons of coal are mined per year (2010), using approximately 200 litres of water per ton. However, the amount of water required hinges on the surface characteristics of the coal being used. M

Coal Slurry: an Idea that Came and Went WyoHistory

Nov 14, 2014  During the coal boom of the 1970s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its destination, where the mixture was dried, then burned. When in the pipeline, the slurry moved along at a leisurely four miles an hour.

Compared with conventional oil agglomeration in stirred tanks, the long-distance pipeline agglomeration yields a superior product in terms of water and oil content as well as the mechanical properties of the agglomerates. The agglomerated coal can be separated over a 0.7-mm screen from the slurry.

Coal Slurry Pipeline

Coal Slurry Pipelines, 13 Hous. L. REv. 528, 537 (1976). 8. The 108-mile Ohio pipeline, built in 1957 in response to high railroad rates, was deacti-vated in 1963 when the advent of the unit train made coal transportation by rail more eco-nomical than by pipeline. In 1957 the railroad rate increased from $2.63 to $3.47 per ton; by

Coal pipeline - Wikipedia

Slurry pipelines use a slurry of water and pulverized coal. The ratio of coal to water is about 1 to 1 by weight. Coal log pipelines use coal that has been compressed into logs with a diameter 5 to 10% less than the diameter of the pipeline and a length about twice the diameter of the pipeline. The ratio of coal to water is about 3 or 4 to 1.
