As young chemical engineers you are responsible for preparing the preliminary design calculations for the pipeline of the last part of benzene production plant. In the plant, benzene is taken at a flow rate of ..kmol/h as the bottom product (ground level) of the purification column and is transported to final storage tank that is ... m away from the column. The bottom of the column, which is the start point of the pipeline, is being operated at 25C and 1.1 atm. The storage tank, which is the end point of the pipeline, is pressurized with nitrogen at 2 atm due to safety regulations. Also, the entrance point to the storage tank is .. m above the ground level. You are expected to i) Estimate the optimum pipe diameter by using the approximate equation given below, i) Decide on the material of pipes (Hint:Check corrosivity from "Safety Data Sheet" for your chemical), i) Decide on type and number of valves and fittings, iv) Calculate the power of the pump (h-0.75) required for the optimum pipe diameter, You must present a detailed sample-hand calculation in your report as well as an explicit diagram of your pipeline with all fittings and valves, etc. Your report should include: Cover page - Statement of the problem - Method of calculations -Assumptions/decisions made - Hand calculation results Discussion (Discussing the assumptions and decisions made) Group Flow rate, Distance, kmol/h Tank Entrance Height, m 1040 450 35 2 1080 440 25 1150 420 30 4 1240 400 25 5 1350 380 35 6 1420 360 25 1500 340 35 1620 320 30 9 1730 310 35 10 1840 290 40 II 1940 270 45 Auxiliary equation for calculation of optimum pipe diameter For D325 mm m is mass flow rate in kg/s, r is in kg/m
