An effluent gas from a refinery with composition CH4, C2H6, C3H8 and C4H10 is fed into an absorber to reduce the propane content of the effluent before recycling. The absorber operated at 37°C and 400 kPa (abs). The entering oil and gas with its composition is shown in the following table. The absorber has 4 theoretical stages. Table 1: The entering oil and gas with its composition Lo, kmol/h VN+1, kmol/h Ki CH4 155 6.65 C2H6 298 1.64 C3H8 212 0.584 C4H10 20 35 0.195 Oil 140 0 0.0001 2.1. 2.2. Do one iteration to determine the liquid and gas flow rates of all the components. What is the total flow for both the liquid and gas outlet as per 2.1? 2.3. Determine the percentage C3H8 (propane) that is removed by the absorber using the answer obtained in 2.1.
