The rotary slurry-powered distributor (RSP) is used to accurately and evenly split a slurry stream into two or more parts, without creating differences based on flow, percent solids, particle size or density. Applications include Splitting streams for feeding parallel lines for any mineral processing application
Preparation. 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 pump to pump the highly abrasive, corrosive and viscous coal slurry. More than 7 billion tons of coal are mined per year (2010), using ...
Abstract: A process to produce low ash clean coal from high ash coal with substantially complete solvent recovery, the process including: forming a slurry of coal fines in a N-Methyl-2-pyrrolidone (NMP) and Ethylenediamine (EDA) solution; maintaining said slurry in a reactor at a temperature range of 100° C. to 240° C. and a pressure range of 1 to 4 gauge (kg/cm2) for a period of about 15 ...
Dec 27, 1983· Substantially dry coal fines are fed into a pressurized zone by slurrying coal fines with a liquid, water-miscible, volatile organic solvent to form a pumpable slurry, pressurizing the slurry, removing and recycling the organic solvent component of the liquid phase of the slurry, thermally drying the pressurized fines and transporting the dried, pressurized fines into the pressurized zone.
In this study, various organic solvents were used to prepare coal slurries and the rheological and thermal properties of coal-organic solvent slurries were examined. Solvents with molecules...
any organic material in it. 3-APS-treated and WDC-grafted silica specimens contain 0.4 and 0.7 mass% of organic sub-stances, respectively. These results show that WDC molecules were bound to the silica particle surface covalently. The WDC-grafted silica particles were dispersed in water to obtain aqueous slurry. The slurry was prepared to a solids
The organic solvents could wet LiAlO 2 powder particles better than water-based solvents and prepare the slurry with lower viscosity and shorter drying time because of its good volatility . The binder could wrap the powder particles, self-cure to form a surface to produce a strong three-dimensionally interconnected resin frame.
In this study, various organic solvents were used to prepare coal slurries and the rheological and thermal properties of coal–organic solvent slurries were examined. Preparation of coal–organic solvent slurries may provide an alternative way to dispose some waste organic solvents generated by various industries. 2.
The basic requirements of organic solvents to be used for sugar seed slurry preparation are as follow. Boiling point of organic solvent be lower than water.So that after introduction of slurry in pans all organic solvent gets evaporated and crystal get spread well. Solubility of sucrose in such organic solvent should be minimum or negligible.
