(a)
Interpretation:
The flowrate of the gas stream leaving the condenser should be calculated
Concept introduction:
It is given that a gas stream contains 18 mole% hexane (rest is nitrogen), this stream is passed through a condenser where some of the hexane is liquefied. The stream properties are given as,
The hexane mole fraction of gas stream leaving the condenser is 0.05 while the liquid condensate is recovered at 1.5 L/min.
Material balance at steady state is,
Material into the system = material out of the system

Interpretation:
The percentage of hexane recovered as the liquid should be calculated.

- Calculate the partial pressure (Pa) of CO2 in a mixture that contains 45% wt CO2, 35% wt CO and 20% wt O2 at 100 deg C and 1.5 atm.arrow_forwardOne type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas. If the temperature drops below-6C, however, N2O may begin to condense out of the gas phase. Thenany gas removed from the cylinder will initially be nearly pure O2; asthe cylinder empties, the proportion of O2 will decrease until the gascoming from the cylinder is nearly pure N2O. In another test, the valve of a 500 L cylinder full of the gas mixture at 2000 psi (gauge pressure) is opened wide so that the gas rushes out of the cylinder very rapidly. Why might some N2O condense during this process? (a) This is an isochoric process in which the pressure decreases, so the temperature also decreases. (b) Because of the rapid expansion, heat is…arrow_forwardOne type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas.

Because these two gases don't react chemically at or below 2000 psi, at typical room temperatures they form a homogeneous single gas phase, which can be considered an ideal gas. If the temperature drops below -6° C, however, N2O may begin to condense out of the gas phase. Then any gas removed from the cylinder will initially be nearly pure O2; as the cylinder empties, the proportion of O2 will decrease until the gas coming from the cylinder is nearly pure N2O.
