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 25°C 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 As young chemical engineers you are responsible for preparing the preliminary design calculations for the pipeline of the last part of benzene production plant.
