Friction and minor losses in pipes - Simulation on Aspen Plus GROUP REPORT (100 points) A 3600 kg/h stream composed by a mixture of alcohols is required to be sent from one storage tank to another storage tank 15 km away passing through a series of pumps and pipes. The conditions for the mixture stream are shown on the table below. Mixture Alcohols 50C 10 atm Conditions Temperature Pressure Composition (wt %) Water Methanol Ethanol Propanol Isobutanol 2-Methyl-1-Butanol 3-Methyl-1-Butanol Ethyl-Acetate 1,2 Diethoxyethane 1.57 0.07 97 0.03 0.43 0.06 0.21 0.18 0.45 The following information is known about the piping system: The Mixture of Alcohols is withdrawn from a storage tank and fed to pump to increase the pressure by 10 bar with an efficiency of 70%. The series of pipes for the first set are divided into two segments, 2 km and 4 km respectively, each with 6" #40 pipe made of Carbon Steel. The first segment contains 4 gate valves, 2 butterfly valves, 12 larges 90-degree elbows, and 20 straight tees. The second segment is at an elevation of 2 meters and contains 6 gate valves, 1 butterfly valves, 4 larges 90-degree elbows, 1 straight tees and 2 Branched tees. The mixture then fed to another pump to with a pressure increase of 5 atm and an efficiency of 65%. Later the mixture is fed to the second set of pipe segments, both adiabatic. The first segment in the second set is 5 km long with an 8" inner diameter and a 50-centimeter elevation. Also, it contains 3 gate valves, 2 butterfly valves, 4 larges 90-degree elbows, 3 straight tees and 2 Branched tees. The second segment in the second set is 4 km long with an 8" inner diameter and a 2- meter elevation. Also, it contains 3 gate valves, 2 butterfly valves, and 1 straight tee. The inlet ambient temperature for the first set are 40C and the outlet 35C. The heat transfer coefficient for the pipes is 5 W/m2.K. The mixture is then sent to storage tank for storage awaiting further processing. After input all these data in Aspen Plus, the simulation has be run successfully. See below the main the results for this simulation. TASK 1. Based on the information given, prepare a report that contains the following (90 Points) 1. Draw the piping system flowsheet (use PowerPoint, Visio or by handwriting) (25 points) 2. Describe the process to run this piping simulation in Aspen Plus (25 points). 3. Calculate Reynold number for the second pipe segment using the parameters given below. What would be the flow pattern? Justify? (20 points). P = 788.71 kg u = 0.0089 poise m v = 0.068 m3 4. What is the total pressure drop for each pipe in atm? Describe briefly the frictional and elevation pressure drops and their contribution to the total pressure drop. (20 points)
