Problem-3 For a stream having composition as shown in Table-2. Solve the Rachford-Rice equation to find out the v, and then find out the vapor and liquid composition. use excel NCOMP (K-1) i=1 1 +(K-1) 0 Rachford-Rice equation, z; is mole fraction; 1 +(K-1) Liquid composition if v' is known. Chemical Propane n-Butane n-Pentane yi= Kai Vapor composition Table 1 Stream data Ibmol/hr Ki 20 3.7 30 1.4 50 0.6 1+(Ki-1)v Hint: First find out K71)2, for each component assuming a value for v'; then set the sum of this to zero by varying v'. Once the value for v' is found, xi and yi can be calculated by using equations given above
