Moreover it may be necessary to re-sulfide the catalyst at periodic intervals. Starting Point: 1. Design Basis: Total Feed Flow Rate, Feed Composition, Direction of Flow, Inlet Operating Temperature, Inlet Operating Pressure: Total Feed Flow Rate (MMSCFD): 15 Total Feed Flow Rate (Nm3 /h): 1.68 x 104 Feed Composition (mol%): H2 N2 CO2 CH4 C2H4 C2H6 C3H6 C3H8 Iso-C4H10 Iso-C4H8 N-C4H10 N-C6H14 H2O TOTAL: 8.209 0.939 0.021 38.480 16.178 13.670 12.957 5.406 0.127 1.868 0.699 0.611 0.837 100.000 Direction of Flow: Downflow Inlet Operating Temperature (o C): Case 1: 300 Case 2: 250 Inlet Operating Pressure (bara): 20 (Assumed)* Maximum Acceptable Exotherm due to Olefin Hydrogenation (o C): Case 1: 80 Case 2: 130 *Please note: The client did not provide an Inlet Operating Pressure.
