1. Natural gas usually contains a mixture of methane and ethane. Methane (CH4) and ethane (C₂H6) undergo combustion in a furnace. Air, along with another stream of pure O2, are fed to the furnace. The reactor effluent, stream A, has a total molar flow rate, composition, and T and P as shown in the schematic. The reactor effluent is fed to a 1st condenser (C1), in which all of the water (and none of the other chemicals) is condensed and removed. The remaining components are fed to a 2nd condenser (C2). However, the maximum capacity through the condenser is 80 kmol/h; the remainder of the reactor effluent bypasses the condenser. All of the ethane (and none of the other chemicals) in the feed to C2 is condensed (hence the reason that this type of natural gas is given the strange name of "natural gas liquid") and removed. The gas stream leaving C2 is mixed with the bypass stream, to form the stack gas. a. Calculate the volumetric flow rate of stream A, in m³/h b. Calculate the volumetric flow rate of stream A in SCMH c. Calculate the partial pressure of O2 in stream A.
