Acetylene (C2H2), a gas used for welding, is converted into ethanol (C2H6O) and butanol C4H10O). A fresh feed of acetylene, H2, and O2 is combined with a recycle stream and is fed to a reactor where the following fractional conversions are achieved: acetylene conversion = 0.750, hydrogen conversion =0.900, and oxygen conversion =1.00. The reactor effluent contains the two products, unreacted components, and CO2 While the reactor effluent contains 1.10 moles CO2 per 1.00 moles ethanol, the stoichiometry of the reactions is unknown. The reactor effluent is sent to a separator where all of the CO2 leaves as a gas. The remaining components are sent to a second separation unit. The bottoms stre am of this unit contains all of the ethanol and butanol products. The process produces 140 mol/min of ethanol and 60.0 mol/min of butanol.

a. Draw and label a process flow diagram. Clearly number each stream.
b. Calculate the molar flow rates (mol/min) of each component exiting the reactor.
c. Calculate the molar flow rates (mol/min) of each component in the fresh feed.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
