Flow rate fugacity coefficient

Symbol for quantum yield. 2. Symbol for one of the space coordinates in the three-dimensional, spherical polar coordination system. 3. Symbol for electric potential. 4. Symbol for volume fraction. 5. With a subscript designation, symbol for a Dalziel coefficient. 6. Symbol for fugacity coefficient. 7. Symbol for osmotic coefficient. 8. Symbol for heat flow rate. 

Finally, we must select appropriate methods of estimating thermodynamic properties. lime (op. cit.) used the SRK equation of state to model this column, whereas Klemola and lime (op. cit.) had earlier used the UNIFAC model for liquid-phase activity coefficients, the Antoine equation for vapor pressures, and the SRK equation for vapor-phase fugacities only. For this exercise we used the Peng-Robinson equation of state. Computed product compositions and flow rates are shown in the table below. 

A stream flowing at the rate of 1000 kmol/h contains acetone (1), methanol (2), and water (3). The stream is sent to a flash drum maintained at 150 kPa and 80°C where it is separated into vapor and liquid products. Calculate the flow rates and compositions of the products using the Wilson equation for the activity coefficients and the truncated virial equation, z = 1 -I- BP/RT, for the fugacity coefficients. Relevant data are provided below ...
