Mixtures condensation

Vapor of the carbon and metal mixture condensed in a gas phase to form black soot, which finally deposited on the inner walls of the arc chamber and on a surface... 

Lagow has carried out reactions between lithium atoms and organo-halogen compounds in the gas phase (19, 20). For example, when CC14 vapor was bled into a dense stream of lithium vapor and the mixture condensed at -196°C, the condensate behaved chemically as if it contained Li4C, e.g.,... 

The sodium hydroxide solution from a large bottle, and at room temperature, is caused to flow at the rate of 1 1. per hour through a pyrex glass tube equipped with an overflow for the solution and another tube for the gas outlet, and an inlet tube of copper or platinum for the fluorine as shown in Fig. 18. The inlet tube, which is sealed into the glass with red sealing wax, dips from 0.5 to 2 cm. into the alkali solution. The fluorine is passed directly from the generator into the inlet tube at the rate of from 1 to 3 1. per hour. If the fluorine is first condensed with liquid air, the yield is said to be very small.2 To the exit tube are attached first a gas wash bottle filled with water, (see Fig. 19) then a trap cooled with a solid carbon dioxide-alcohol mixture, and finally another trap cooled with liquid air. The OF2 is freed from any fluorine in the wash bottle, and the water vapor is frozen out in the first trap. The OF2—02 mixture condenses to a pale-yellow liquid in the... 

The synthesis forms a mixture of 60-80% of ethylchlorosilanes and 20-40% of unreacted ethylchloride. This mixture (condensate) is then sent to rectification. The diagram of the distillation of unreacted ethylchloride and the rectification of ethylchlorosilanes is similar to the diagram given in Fig.4. After the distillation of unreacted ethylchloride at 0.2—0.25 MPa the ethylchlorosilane mixture is rectified. The mixture has the following average composition (%) ... 

A vapor mixture ofmethanoK 1) and water(2) containing 56-mol-% methanol enters a condenser at 101.33 kPa at its dew point of 82.85 C. It is completely condensed and leaves the condenser at its bubble point of T2.05°C. How much heat must be transferred in the condenser for each mole of mixture condensed The latent heat of vaporization of methanol at its normal boiling point of 64.7°C is 35,228 J mol-1. The heat of mixing of a liquid mixture containing 56-mol-% methanol at 72°C is estimated as -500 J mol-1. 

The reaction mixture, condensed in the traps as a slurry, is first washed with potassium hydroxide solution to remove acidic components. The product is then fractionated to separate the greater part of the NgO. At this stage, the NFg becomes a colorless liquid covered with a white layer of solid NgO. In order to remove this, the NFg must be repeatedly and very carefully fractionated. The last traces of NgO may be more conveniently separated by filtering the NFg at —196°C on a low-temperature filter. It is completely pure after only one filtration. Finally, the air dissolved in the NFg is removed, using an oil pump vacuum for several hours, while the trap with the product is immersed in liquid nitrogen. Purity is best ascertained by molecular weight determination (vapor density measurement). 

Water/hydrocarbon mixture Condensation, separation of the liquid water/ben-zine. The waste gas is ignited and the wastewater is fed to a treatment plant, e) Recovery of methanol and toluene [115]. During the production of a textile chemical a solution (mother liquor) is produced containing methanol and an aromatic solvent (toluene or xylene). An azeotrope containing methanol and toluene is produced by discontinuous ditillation. The toluene-containing phase separates out on addition of water. Methanol is recovered from the methanol-containing phase by continuous... 

The pressure and temperature drop along the nozzle or throttle lead to supersaturation of the mixture. Condensation of water vapor or heavy hydrocarbons in the flow is then possible. Since the residence time of the mixture in the nozzle or throttle is short, fine drops (fog) formed will not have enough time to increase in size to any appreciable extent. Therefore, the main growth of drops should occur in the flow beyond the exit of the nozzle or throttle, where the outflow of the gas jet forms in space as in a divergent nozzle. 

Solvent recovery stills are designed to reclaim vapor degreasing solvents by removing contaminants such as grease, oil, rosin solder/flux, and pitch. The reclamation process is accomplished by boiling the solvent/contaminant mixture, condensing... 

An automatic and manual primary system depressurization line which is connected to the pressur-izer top and terminates in a mixture condenser. 

A mixture condenser of the indicative volume of about 1500 m, of which 500 m are initially occupied by borated water at 2000 ppm boron and the rest by nitrogen. The function of this component is the collection of the fluid discharged by the primary system and the confinement of the fission products contained in it, the dissipation of its thermal energy to the outside environment and the formation of an additional reserve of water for the long-term cooling of the core, that is beyond the 10 hours (by natural or forced circulation, using the low power pumps, according to the...

Air with a volumetric composition of 79% nitrogen and 21% oxygen is cooled to 80 K at a pressure of 0.101 MPa. Determine the fraction of the mixture condensed and the mole fraction of nitrogen in the resulting vapor and liquid phases. Use the equilibrium constants for the two components involved.
