1.1.2- Trichloroethane permeation rate

TRICHLOROETHANE PERMEATION RATE PROPERTIES FOR PROTECTIVE GARMENT MATERIALS... 

A second method of determining the coefficient ( >,/5) and the intrinsic enrichment of the membrane Ea is to use Equation (4.11). The term ln(l — 1/E) is plotted against the permeate flux measured at constant feed solution flow rates but different permeate pressures or feed solution temperatures. This type of plot is shown in Figure 4.10 for data obtained with aqueous trichloroethane solutions in pervaporation experiments with silicone rubber membranes. 

Figure 4.10 Trichloroethane enrichment [ln(l — 1/E)] as a function of permeate flux Jv in pervaporation experiments with silicone rubber membranes in spiral-wound modules using solutions of 100 ppm trichloromethane in water [15]. Feed solution flow rates are shown...
