If the feed enters the distillation column at its dew point, then the ...
Explanation: If the feed at dew point means the feed condition is saturated vapour so the enthalpy of feed is same as the enthalpy of the vapour. Therefore the slope of the Q-line is 0. Since Q-line is the Flash vaporization operating line.

The slope of the Flash vaporization operating line when the feed enters the distillation column at its dew point is 0.
- **Explanation**:
- **Definition**:
- The Flash vaporization operating line represents the relationship between the liquid and vapor compositions at equilibrium during the flash vaporization process.
- **Dew Point**:
- When the feed enters the distillation column at its dew point, it means that the feed is at its maximum vapor pressure for a given temperature.
- At the dew point, the liquid and vapor compositions are equal.
- **Slope of Operating Line**:
- Since the liquid and vapor compositions are equal at the dew point, the slope of the operating line is 0.
- This is because any change in the liquid composition is not accompanied by a change in the vapor composition, leading to a horizontal line on the composition diagram.
- **Conclusion**:
- Therefore, when the feed enters the distillation column at its dew point, the slope of the Flash vaporization operating line is 0.
