Generate a specific mass balance table and an energy balance table to produce retinol in oil. The unit operations with their respective yields are: - Bioreactor (100%) to generate biomass, dodecane is added to extract retinol, retinal and B-carotene. (12.4 kW/hr for 8hrs) - Decanter (97%) to remove medium and biomass. (0.6kW/hr for 0.5hr) - Settler-Mixer (79%) to remove dodecane by adding methanol. (0.97 kWh for 1.5h) - Microfiltration (95%) to decrease the flow to 1% of the input volume. 1.1kW/hr for 1hr) - HPLC (90% to remove retinal and B-carotene. (1.8kW/hr for 18hrs) - Evaporator (98%) to remove methanol. (253.3 kWh for 4h) - Oil mixer to add the pharmaceutical grade oil that represents 99.5% of the total product. 3kW/h for 3h) It is looking to have a production of 1.36 kg of Retinol to cover the annual demand. Consider the following: - The solubility of dodecane in methanol is 88 g per 100 g of MeOH. - Consider that 3000 kg of MeH enter the Settler-Mixer - Consider that yeast produces the following amounts of compounds per gram of biomass: 2 g retinol, 3.5 g retinal, 0.15 g B-carotene. - Consider that the yeast grows 80g/L of xylose in a medium composed of 20% dodecane, 30% liquid medium and 50% xylose.
