Question:
Draw and label the flow chartn
You already settled on a deal for your raw “ethylene”: On a monthly basis, you will receive a shipment of 4.37 mega grams of this hydrocarbon gas, which contains 0.86 ethylene and 0.14 acetylene in terms of molar fractions. You store this raw “ethylene” in a cylindrical tank capped at the top and bottom by hemispheres.
In a mixer, you merge this hydrocarbon gas with a recycle stream, while also connecting it with the creek nearby, which is essentially pure water. The reactor then consumes ethylene and acetylene, and it generates ethanol and acetaldehyde; notably, you have two options for the catalyst in the reactor. The separator in turn perfectly splits between gases and liquids: The recycle stream takes all ethylene and all acetylene, while having no other species in it. The other two streams of the separator are liquids, with one being an aqueous phase and one being an organic phase. You discharge the aqueous liquid in the creek. On the other hand, you store the organic liquid in a cylindrical tank which has flat top and bottom lids. The ultimate aim of your plant is for the organic liquid to have a composition more or less equivalent with commercial “ethanol”, which contains 0.70 ethanol and 0.00 acetaldehyde in terms of molar fractions (0.30 water is also present); you will eventually trade this organic liquid on the market.
