what is slurry pipeline

Slurry pipelines offer an economic advantage over railroad and much less noise disturbance to the environment, particularly when mines are in extremely remote areas. Slurry pipelines are also considered to de-silt or remove silts from deposits behind dams in man-made lakes. After the Hurricane Katrina disaster there have been proposals to pump ...

Slurry Pipelines Abstract Fluor is developing its expertise in cold flow technology as well as in the transport of hydrates in a slurry form. Fluor has filed a provisional patent application on self-lubrication of hydrate-based slurry pipelines. It is estimated that there are very large reserves of hydrates in the Arctic and near Japan.

Slurry pipeline was first introduced to reduce cost in transporting coal to power generating units. Since then this technology has caught-up worldwide to transport other minerals such as limestone, copper, zinc and iron.

A suspension of solid particles in a liquid, as in a mixture of cement, clay, coal dust, manure, meat, etc. - with water is often called a slurry. In transport systems for slurries it's important to avoid settling of solids by keeping the fluid velocities in the pipe lines above certain levels.

Pipeline transport of minerals became of interest in 1967 after Bechtel constructed the world's first iron ore slurry pipeline: the 85-km-long Savage River project in Tasmania. Since then, long-distance slurry pipeline transport has become quite commonly adopted for mineral concentrates. Interest has increased in the alumina industry,

The slurry used in this investigation is from the Black Mesa pipeline. Using coal slurry for coal log transport in pipeline has two major advantages over water. First, the slurry will reduce the amount of water (50% by weight) required to transport the coal logs and increase the coal throughout.

Slurry Pipelines. They currently serve to transport metal ores and coal suspended. in water. Their greatest potential is for transporting coal from. Western states to power stations in other parts of the country. Most of the coal in the U.S. (an. estimated 72 percent of the.

The principles of good slurry pipeline design, suspension, and handling have been well defined since the early 1950s. However there have been significant refinements to detailed hydraulic design. In most cases the strategy is to make a settling slurry into a non-settling slurry so that it can be treated as a normal, homogeneous fluid. Settling ...

As the flow in slurry pipelines cannot normally be stopped because the suspended particles would then settle out and partially or fully plug up the pipeline, it is necessary to maintain a continuous flow in the pipeline. The pipeline must therefore be full of liquid and/or slurry material at all times. During below-capacity operation, this is ...

K is the slurry consistency index n is the slurry flow behavior index. Case Study. The material handling problem stated that a fine limestone with specific gravity of 2. 661 and concentration by weight of 58.3% was to be transported at a rate of 200 dry short tons per hour, in the form of a slurry, by a pipeline over a distance of 11.74 miles.

The concentration of solids in the slurry — measured as a percentage of the total volume. The length of the pipeline. The longer the pipeline, the greater the slurry-induced friction that will need to be overcome by the pump. The slurry pipe diameter. The static head — i.e., the height to which the slurry must be lifted in the piping system.

Our Abrasiguard polymer lined slurry pipelines are the result of years of research and development. We've created a liner that resists corrosion and has world-leading wear performance. Slurryflex mining hose offers premium flexibility and durability. It's ideal for sections of the pipeline that have changes in elevation or direction.

Slurry pipelines are conventionally designed to operate without a deposit on the pipeline invert - i.e. the minimum operating velocity is greater than the deposition velocity. Largely this approach has been adopted due to concerns regarding potential blockage of a pipeline operating with a deposit.

These slurry pipelines are generally only a few kilometers in length and designed to transport a wide and varying range of solids. The solids pumped can range from the very finely ground materials to very coarse rock or coal, and are usually the wastes mining processes. These pipelines are those that also carry the pastes and thickened tailings.

Long distance slurry pipelines are widely used in the mining industry and, compared to bulk transport systems, have a good performance record for high-availability, excellent safety, and profitability in transporting mineral concentrates such as coal, copper, iron, phosphates, and oil sands.

A slurry line is a series of pipes or hoses that transport the drilling mud (suspension fluid) from the face of a tunnel excavation, via discharge pumps, to a separation system at the ground surface. The drilling fluid is then recycled and pumped back to the cutting head to facilitate further advancement of the drill. Advertisement

Slurry Pipelines. In the case of the slurry pipeline, for example, wall perforation by wear usually occurs on the outside curve of a bend, and it is the wear rate at that point that will determine the lifetime of the system, not the average wear rate at other locations. From: Tribology (Second Edition), 2017. Related terms: Slurry; Erosive Wear

of slurry particles inside the line and to determine the optimum pipeline veloci­ ty. If the velocity was too low, the slurry particles would start settling out of sus­ pension, scrape along the bottom of the " pipe and erode it. If the velocity was too high, energy would be wasted propelling the slurry and again there would be ex­ cessive ...

Slurry is a fluid suspension of small particles in liquid. In trenchless construction, there are many methods and practices which include a slurry mixture. The use of slurry allows for the rapid movement of solid particles during the excavation process, and it is useful in applying pressure to stabilize a borehole.

As Ausenco notes, "slurry pipeline technology is a safe transportation alternative that minimises impacts on local communities and the environment. Its benefits include lower pollution levels, fuel costs and staffing requirements, and a reduced reliance on high-use transport corridors.
