C. High-Pressure PVT Properties. Three methods are presently being used to measure the high-pressure PVT properties of electrolyte solutions volumetric methods, (26,32,106) high pressure magnetic float systems, (36,107,108) and high pressure speed of sound systems (109,110,111,112). I will not attempt to review all the modifications made to these systems.

The solution volumetric flow rate in the feed side is approximately equal to that in the permeate side. Therefore, we have... 

The second component in Eq. (3), 2<,cCs( A7t), represents the solute volumetric flux, driven by osmotic pressure gradient. Osmotic mass-transfer coefficient corresponds to the osmotic overall mass-transfer coefficients fCrtF on the feed side and on the strip side of the BAHLM system which... 

Since carbon tetrachloride and water are virtually immiscible (see Illustration 11.2-3), we will assume that the liquid bromine is distributed between water-free carbon tetrachloride and water free of carbon/tetrachloride. Also, since solution volumetric data are not available, we will assume that therfe is no volume change on mixing bromine with either carbon tetrachloride or water.

If Sets I and II components were pre-mixed by weight, then to each calibration solution volumetric flask or vial, weigh appropriate volumes to yield the ten calibration solutions. Calculate the actual weight of each component by multiplying the total mass added of the combined mixture by the mass fraction of the individual components in the pre-mixed undiluted mixture.
