Solids specific gravity

Ethoxylation of alkyl amine ethoxylates is an economical route to obtain the variety of properties required by numerous and sometimes small-volume industrial uses of cationic surfactants. Commercial amine ethoxylates shown in Tables 27 and 28 are derived from linear alkyl amines, aliphatic /-alkyl amines, and rosin (dehydroabietyl) amines. Despite the variety of chemical structures, the amine ethoxylates tend to have similar properties. In general, they are yellow or amber liquids or yellowish low melting solids. Specific gravity at room temperature ranges from 0.9 to 1.15, and they are soluble in acidic media. Higher ethoxylation promotes solubility in neutral and alkaline media. The lower ethoxylates form insoluble salts with fatty acids and other anionic surfactants. Salts of higher ethoxylates are soluble, however. Oil solubility decreases with increasing ethylene oxide content but many ethoxylates with a fairly even hydrophilic—hydrophobic balance show appreciable oil solubility and are used as solutes in the oil phase.

Once the phosphate matrix is pumped or transported, it is processed in a special phosphate rock treatment plant. Nordin (1982), of the Phospnate Development Corporation Ltd., described how each year a South African plant produces approximately three million tons of phosphate rock from foskorite and pyroxenite ores. The ore was then classified through flotation, thickening, and filters before being stockpiled. The result was fine gray-white crystalline powder of mineral apatite, with a 36.5% P2O5 content, a solid specific gravity of 3.17, and 106 p,m. The hardness of the apatite was measured at 5.0 on the Mohr scale. 

In the present study, experiments were conducted to determine the individual effects of solid properties (particle size, solids specific gravity) and solids concentration by weight, as well as tip clearance effects on an open impeller centrifugal pump characteristics. Tip clearance is varied from 1.25 mm to 8 mm over the experiments and maximum particle size was approximately 2.4 mm. Test results have shown that, slurry characteristics and running tip clearance have a considerable impact on the pump performance. These effects, therefore, must be taken into account for piunp design considerations and selection.
