Problem S-3a. A pipeline containing natural gas from a hydraulic fracturing process contains 80% methane gas (CH4, species A) and 20% ethane (C₂H6, species B) gas at 3.0 atm and 17 ,C. We are concerned that if the pipeline leaks, then the gas mixture can transfer through the porous layer above the pipeline and ultimately escape to the atmosphere, as shown in the Figure below. What is the molar concentration of ethane (B) gas inside the pipeline? (a) What is the molecular diffusion coefficient of methane gas (CH4, species A) in ethane gas (C₂H6, species B) inside the pipe (P = 3.0 atm)? Compare results from two appropriate correlations. gas leak to atmosphere porous layer 17 °C, 1.0 atm &= 0.3, dpore = 0.001 cm 80% CH4 gas, 20% C₂H, gas 30 atm 176 pipeline

Problem S-3a. A pipeline containing natural gas from a hydraulic fracturing process contains 80% methane gas (CH4, species A) and 20% ethane (C₂H₁, species B) gas at 3.0 atm and 17 C. We are concerned that if the pipeline leaks, then the gas mixture can transfer through the porous layer above the pipeline and ultimately escape to the atmosphere, as shown in the Figure below. What is the molar concentration of ethane (B) gas inside the pipeline? (a) What is the molecular diffusion coefficient of methane gas (CH4, species A) in ethane gas (C₂H₁, species B) inside the pipe (P = 3.0 atm)? Compare results from two appropriate correlations. gas leak to atmosphere porous layer 17 °C, 1.0 atm & = 0.3, dpore = 0.001 cm 80% CH4 gas, 20% C₂H² gas 2 6 3.0 atm, 17 °C pipeline
