Question
300 L/h of 20% mol (30% = C₃H₈, 80% n-C₄H₁₀ mixture at 0°C and 1.1 atm and 500 L/h of a 45% mol (45% = C₃H₈, 55% n-C₄H₁₀ mixture at 25°C and 1.1 atm are mixed and heated to 227°C at constant pressure. Enthalpies of propane and n-butane are listed below. Assume ideal behavior. | °C | Propane ΔH(J/mol) | Butane ΔH(J/mol) | |-----|-------------------|------------------| | 0 | 0 | 0 | | 25 | 1772 | 2394 | | 227 | 20,965 | 27,412 | Calculate the heat requirement in kJ/h.
