Q2: A mixture of natural gas consisting of (G1-4.5%, Cz-13.0%, C3-22%, i-C4-17%, n-C4 -7.6%, i-C5-12.4%, n-C5-5%, n-C6 -4%, G7 - 5% and Cg. - 9.5 %) at 166 C and 1.37 bar is fed into a compressor that has only 56% efficiency. The flowrate of the natural gas is 58810 kg/h and its outlet pressure from compressor is 3.98 bar. Use SRK property package to determine; [2.5x4=10 marks] 1- 2- Energy requirement "Q-2020" in compressor (kW): Outlet temperature of natural gas (C): Compressor outlet stream is now sent to an expander for pressure reduction to 2.74 bar (stream pressure). Calculate; 3- 4- Energy requirement expander (kW): Outlet stream temperature (°C): Note: To create hypothetical component, use boiling point of 119 C Component list name MUST be your first name and last 5 digit of your ID (example / 'Ahmad12345'). Property package name MUST be Arabmission 21 (Rename to 'Arabmission21').
