Ethаnоl (C2H5OH) is cоmmоnly used аs а fuel in cars, particularly in countries with abundant agricultural resources, due to the financial advantages of producing ethanol from starch. However, a significant challenge in ethanol-fueled cars is the low conversion (fractional conversion) of ethanol in many engines, which results in the emission of unburned fuel into the atmosphere, leading to various environmental concerns. To mitigate this issue, unburned fuel should be recycled back into the engine to reduce fuel waste. Ethanol, with a flow rate of 920.0 g/hr, enters the reactor (engine) through the feed stream, along with 300.0% excess pure oxygen, which is introduced via the same stream. The single-pass fractional conversion of ethanol is 0.1000, while the overall fractional conversion reaches 0.8000. One stream (gross product) exits the reactor and enters the filter (separator). The filter separates this stream into two parts: a recycle stream containing only ethanol, which is sent back directly to the reactor (engine) and an exhaust (product) stream that leaves the system. C2H5OH + O2 ----> CO2 + H2O (not balanced) Based on the above information, answer the following questions including all of the steps of problems solving: Create an appropriate engineering diagram with correct labeling. Perform a degrees of freedom (DOF) analysis for the reactor, separator, and overall subunit. Determine the molar flow rate of the product stream and its composition (in mol%). Calculate the molar ratio of the recycle stream to the gross product stream (report in fraction format with proper sig figs).
