Problem 1. Was it even worth it? In our lab, we conducted experiments to determine the material and energy requirements for making biodiesel. Now, we can use the data we collected to make a few economic calculations. You will need to make assumptions and conduct research to complete this problem. As always, be sure to show your work and cite references using an appropriate format. a.) Draw a PFD for a continuous process to convert a stream of waste vegetable oil to biodiesel and soap. You do not need to include pumps and storage tanks, just the main unit operations. Be sure to include a stream and mass flowrate for all of the chemicals you used in the lab. Scale all your measurement such that the process produces 10MM gallons/yr. This is the actual size of a biodiesel plant in Stockton, CA. Source: https://canarybiofuels.com/what-we-do/\#facilities b.) How much total energy (in kWh ) did you use in the four labs? How much would the large scaled plant use? Use MS Excel to create a pie chart with the energy use from each piece of equipment in each lab. Which step of the process required the most energy? c.) How much energy is in a gallon of biodiesel? Compare this value to how much energy you calculated in part b. You may need to perform a few unit conversions to make a comparison. d.) Calculate the minimum selling price for a gallon of biodiesel using your material balances. You will have to research chemical and energy prices. Care should be taken to identify the bulk price for each chemical (usually $ per metric tonne). You should assume that our process will use waste vegetable oil as a reactant which still has a market price. This is estimate will be a best-case scenario as we are not including the price of labor, land, or equipment. Recalculate the price per gallon using fresh vegetable oil. e.) Assuming that we plan to pursue this process further, what is the next experiment you would conduct? Your argument should be supported by calculations or data from your experiments
