Question

A gas mixture at 300K and 1 bar analyzing by volume 20% N2 and 80% CH4 is subjected to
liquefaction at the rate of 1500 kg/hr. It is found that only 30% (weight) of the entering gas is
liquefied and the concentration of N2 in the liquid is 60% by weight. The unliquefied gas leaves
the unit at 273K and 1 bar. Determine (a) the volume of the unliquefied gas, m3/hr (b) the
composition of the gas leaving expressed as volume %.​

Answer 2

Explanation:

A gas mixture at 300K and 1 bar analyzing by volume 20% N2 and 80% CH4 is subjected to

liquefaction at the rate of 1500 kg/hr. It is found that only 30% (weight) of the entering gas is

liquefied and the concentration of N2 in the liquid is 60% by weight. The unliquefied gas leaves

the unit at 273K and 1 bar. Determine (a) the volume of the unliquefied gas, m3/hr (b) the

composition of the gas leaving expressed as volume %.​

1373.93 $m^{3}$

$N_{2}$ = 10.97%

$CH_{4}$ = 89.03%
