Hydrotransport

Pipelines to transport soHds are called freight pipelines, of which three different types exist pneumatic pipelines, the use of which is known as pneumotransport or pneumatic conveying slurry pipelines, which may also be called hydrotransport or hydrauHc conveying and capsule pipelines. When air or inert gas is used to move the soHds in the pipeline, the system is called a pneumatic pipeline and often involves a wheeled vehicle inside the pipeline, propelled by air moving through the pipe (25). Slurry pipelines involve the transport of soHd particles suspended in water or another inert Hquid. HydrauHc capsule pipelines transport soHd material within cylindrical containers, using water flow through the pipeline for propulsion. [Pg.48]

Fiber Slurry Pipelines. Pipelines to carry suspensions of wood, paper, sludge, etc, have found commercial acceptance. Most of them are less than 15 km long but have diameters of up to 500 mm. These slurries are often concentrated and display viscous plastic properties, although particle sizes may vary special pumps are used. One such hydrotransport system carries a cellulose slurry by pipeline from the plant to a paper plant near Heidenau, Germany. The 250-mm dia pipeline carries 60 t/d over the 3-km distance to thickeners. In Sweden, a 3.7-km, 500-mm dia pipeline moves cellulose by... [Pg.48]

It follows from the foregoing research concerning the most effective carrier liquid for the coal hydrotransport that the majority of authors recommend to use methanol and its water solutions as a carrier liquid instead of water, [11-19]. A choice of the methanol as a carrier liquid for the transport of coal is not accidental. According to [20] and [21] the simple and fairly reliable production of methanol can put it forward in the category of the cheapest products of organic synthesis in the near future. [Pg.375]

An annual world production of methanol increased already at present in average about 15%. The majority of methanol is now produced from petroleum or natural gas since it is about 25-50 % cheaper than production from coal. However, according to the economical prediction the difference in prices should be essentially decreased in the near future. Methanol as a carrier liquid for the coal hydrotransport offers the following scheme of the coal pipelining. [Pg.375]

The comparison of hydraulic capsule pipeline transport with pipeline transport of oil products and slurry hydrotransport is particularly interesting. [Pg.379]

It was demonstrated that power consumption for transport of the same quantity of bulk cargo placed in capsules is less than in case of slurry hydrotransport, especially, for coarse-grained material of density of coal and different types of industrial wastes. [Pg.380]

Many of the applications of colloid and interface science to the mining and mineral processing industry can be found in the hydrotransport, flotation, and tailings processes. Although suspensions feature prominently in each of these, a range of emulsions, foams and suspensions can be found in this industry. Some examples are given in Table 10.1. [Pg.243]

Automated units with columns of the same type have been described in [68]. The operations of loading, unloading, and transferring ion exchanger (hydrotransport) are mechanized and controls for positioning the sorption fronts and regulating the operating conditions are automated. The scheme of this unit is represented in Fig. 26. [Pg.70]

These tables indicate that thermo-hydrotransport processes coupling leads to increasing wastes spatial spreading. For the activity it is mostly upward spreading due to temperature effect, while for TDS concentration it is more downward spreading due to density effect. [Pg.751]
