A gas mixture flowing at a rate of 100 lb-mole/hr containing 55 mole% SO₂ and the balance is air contacted with liquid water (89700 lb-mole/h) in a continuous absorber. Assuming that the gas and liquid streams entering and leaving the absorber in equilibrium at 30°C and 1 atm, calculate the molar flow rate of the SO₂ in both outlet streams. (SRK)

Natural gas contains 81 mol% methane and 19 mol% carbon dioxide is pumped through a horizontal Schedule 40, 6-in.-diameter cast-iron pipeline at a mass flow rate of 610 kg/h. If the pressure at the pipe inlet is 3.45 bars and 23°C, the pipeline length is 1.9 km downstream. If the ambient temperature is 25 C and the pipeline without insulation, calculate the pressure drop across the pipe . (SRK)

Consider the following mixture: CO, 105kmol/h; Co₂, 210 kmol/h; O₂, 90 kmol/h. The gas at 15 atm and mass enthalpy -6083 kJ/kg. Find the gas temperature. (SRK)

A compressor is used to compress 100 kg/h of natural gas consisting of 80 mol% methane, 10% ethane, 5% carbon dioxide, and the remaining nitrogen from 3 bars and 30°C to 10 bars. Find the compressor duty (SRK)

Consider the following liquids phase reactor in an isothermal CSTR

Ethanol + Diethylamine  -------- >  Triethylamine + Water

The inlet at pressure 354.5 kPa, temperature 50 C and flow rate (kgmol/hr), 50 Ethanol, 50 Diethylamine and 95 Water. With A=4775 kgmol/m³-hr, activation energy E=10000 J/mol. If the reactor volume is 4440.8 L, what percent conversion of ethanol will be achieved? (PRSV)
