5 + 32 # Bubble-point temperature # c) In this method, we use L-R rule, instead of simple Raoult's law # So, # y_i = (x_i*p_i)/(v_i*P) # Where calculated values of v_i from EOS are given in the table 10.A and are v_e = 0.950 # For ethane v_h = 0.459 # For n-hepmath_tane # We again use trial and error on the temperature # Let us assume the initial temperature Ti = 50. # Now, we horizontally from that intersection point to the dew-point curve, finding the vapor phase composition of ethane y1_e = 0.92 y1_h = ( 1 - y1_e ) # b) By Raoult's law, we use a trial and error procedureon the temperature # Antoine equation consmath.tants for ethanol are given A_e = 6.80267 B_e = 656.4028 C_e = 255.99 # and that for n-hepmath_tane are A_h = 6.9024 B_h = 1268.115 C_h = 216.9 # Antoine equation is given by # (math.log10p) = (A - B/(T+C)) T = 50. # Bubble point pressure x_ethane = 0.10 # Mole fraction of ethane in liquid phase x_hepmath_tane = ( 1 - x_ethane ) # a) From figure 10.7( page 260 ) given in the book # We read the chart to get the bubble-point temperature # The dew point curve for 100 psia crosses the 10 mol% ethane line at about temperature T1 = 165.
