Heavy liquids

Solids of different densities can be separated by immersing them in a fluid of intermediate density. The heavier solids sink to the bottom and the lighter float to the surface. Water suspensions of fine particles are often used as the dense liquid (heavy-medium). The technique is used extensively for the benefication (concentration) of mineral ores. [Pg.406]

B/Si is the molecular diffusion term and relates to diffusion of solute molecules within the mobile phase caused by local concentration gradients. Diffusion within the stationary phase also contributes to this term, which is significant only at low flow rates and increases with column length. As B is proportional to the diffusion coefficient in the mobile phase, the order of efficiency at low flow rates is liquids > heavy gases > light gases. [Pg.89]

The objective of this work was to study the activity of the Monolith catalyst for removing sulfur and nitrogen from a Synthoil process liquid (heavy stock) and Raw Anthracene Oil (light feedstock), and to make a preliminary assessment of the advantages and/or disadvantages of the Monolith catalyst over a commercial catalyst used in the petroleum industry. [Pg.210]

Describing the behavior of undefined mixtures, whether from natural or synthetic sources, often begins with the separation of these complex systems into effective pseudocomponents by distillation (1 ). Each pseudocomponent is then characterized as if it were a pure compound, and its characterization data are used in appropriate correlations. The presence of nonvolatile residuum poses a serious limitation to such methodology. For coal-derived liquids, heavy crude oils, tar sands, and shale oil, more than 50 percent of the fluid may not be distillable (JL). Since this nonvolatile residue cannot be separated using conventional techniques, new methods of separation and characterization must be developed to provide the necessary information for design and operation of plants utilizing the fossil fuels mentioned above (2). [Pg.229]

The ether sulfates are used in light-duty liquids, heavy-duty powders, and shampoos. [Pg.107]

Heavy-Duty Liquids, Heavy-duty laundry liquids have gained much importance and much interest in the literature over the last few years. Products in the industry today include both built and nonbuilt heavy-duty liquids. Built heavy-duty liquids are those which contain a builder such as tetrapotassium pyrophosphate (TKPP) or sodium citrate in order to sequester calcium and magnesium hardness ions. Nonbuilt heavy-duty liquids contain no builders and make up for that shortage by considerably increased active contents in order to maintain performance(8-14). Built heavy-duty liquids can have either of the following types of formulations ... [Pg.110]

HVL-P represents about 70% of condensed-phase product (CPP) (viz. liquid and solid products) which includes light liquid, heavy liquid, and char. An estimate showed that the average aromatic cluster size of CPP is 2.2, which is practically the same as that of HVL-P. This indicates that HVL-P has the average chemical characteristics of CPP. This estimate was made by assuming that the light liquid and the char were similar to Light and Resld of HVL-P, respectively, in molecular weight and cluster size. If we assume that CPP retains any stable structural features of the feed coal then HVL-P would reveal such structural features. [Pg.233]

The bath was turned on the day before the experiments. The equilibrium cell and all the lines were first evacuated. Then, the liquid heavy component was loaded from a scaled glass tank above valve V7. Carbon dioxide was finally pumped into the cell from a cooled storage unit through valves VI and V3 until the desired level of pressure was attained. The pressure was measured by a Data Instruments pressure tranducer model AB (range 5000 psi) with an accuracy of 0.1 bar. The temperature inside the cell was measured by a thermoresistance sensor (PT100Q) within + 0.1 °C. [Pg.412]

X2R. Now we can take (JCC as 256 kHz and neglect the small value according to a recent quantum mechanical and molecular dynamic study on liquid heavy water between 260 and 359 In organic solvents, a gas-phase value of 308 kHz is used because of very weak H bonds between a water molecule and solvent molecules. Furthermore, we assume isotropic rotation... [Pg.150]

Two experiments (RSI, RS2) were performed with DC-II and Swedish wheat straw with particle size in the range of 1 to 2 mm. During these experiments the solids recovery system (cyclone and impinger, Figure 1) did not perform satisfoctorily with the very fragile straw char. The char, exposed to the very harsh envirorunent (fast moving sand particles) of the CFB reactor and atritted to very fine particles, almost submicTon powder, could not be collected by conventional solids recovery systems. Consequently, the char was either adhered with the liquids heavy fraction to the STHE inner tubes or readilly accumulated in the liquid recovery system. [Pg.1262]

For example, in the decanter shown in Fig. 2.6 let the density of the heavy liquid be and that of the light liquid be p. The depth of the layer of heavy liquid is and that of the light liquid is Zj,. The total depth of liquid in the vessel is fixed by the position of the overflow line for the light liquid. Heavy liquid discharges through an overflow leg connected to the bottom of the vessel and rising to a height Z j above the vessel floor. The overflow lines and the top of the vessel are all vented to the atmosphere. [Pg.35]
