it should be v7 not v3 since the theoretical stages are 7. Please show the formula you used and tabulate the answers.

QUESTION 1 The heavier component has to be removed from a gas stream by absorption. The absorption column operates at 2 000 kPa and 40C. The entering oil and gas with its composition and K-values can be found in Table 1. The oil and gas are fed to a stripper with 7 theoretical stages, where the lighter components are stripped by superheated oil. The effluent gas enters the absorber at 750 kmol/h and the total molar flowrate of the oil entering the absorber is 195 kmol/h. It can be assumed that A and S values can be based on the entering values of L and V, and K-values are constant. Table 1: K-values for components Component LO(mole V8 (mol fraction) K-values fraction) CH4 0.23 6.65 C2H6 0.407 1.64 C3H8 0.33 0.584 C4H10 0.1 0.03 0.195 C5H12 0.05 0.003 10.0713 Non-volatile oil 0.85 0.0001 1.1. Calculate the molar flowrates of the components entering the absorber in the liquid stream and the effluent gas stream. Tabulate your answers. (4)
