If the feed to a flash drum has a composition z Whats the r

If the feed to a flash drum has a composition z,

• What’s the ratio (L/V) for the mole fraction of the more volatile component to be minimum in the liquid stream leaving a flash drum?

• What’s the ratio (L/V) for the mole fraction of the more volatile component to be maximum in the vapor stream leaving a flash drum?

• As the ratio (L/V) increases, does the temperature of a flash drum increase or decrease if the pressure is fixed?

Solution

As the ratio (L/V ) increases the temperature of a flash drum increases if the pressure is fixed.
