Solution to Tutorial 4 Given: F = 1000 kg-mole/hr‚ xF = 0.20 (ethanol is MVC) Feed is saturated liquid‚ thus q = 1.0 xD = 0.80‚ xB = 0.02 (maximum); R = 5/3 First‚ plot the equilibrium curve using the VLE data given. Note that you need to convert mole% ethanol into mole fraction. Then‚ apply the McCabe-Thiele method to find the number of theoretical (equilibrium) trays required for the separation. Step 1: Since R and xD are known (5/3‚ and 0.80 respectively)‚ plot the ROL equation - it

the help of acetone we saw the spectrum and the differences of the different pigments. Percentage transmittance in Table 1 show that the lower the number‚ the more dense that solution is at that specific wavelength. As the numbers get higher‚ the less dense it is and if the number is 100 at a specific wavelength then the solution was clear. As we can see from Table 1‚ each of the pigments had different low transmittance based on how high the absorption was in each of the pigments. For this we calculated
