Distillation is a process of separating two or more components based on their boiling points.

• VLE (Vapor-Liquid Equilibrium) is a graph that shows the relationship between the vapor and liquid phases of a mixture at different temperatures and pressures.

• The components with lower boiling points will vaporize first and can be collected as the distillate.

• The components with higher boiling points will remain in the distillat...read more

Line sizing involves determining the appropriate diameter of a pipeline for a given flow rate and fluid properties.

• Determine the required flow rate and fluid properties

• Calculate the Reynolds number to determine the flow regime

• Select an appropriate friction factor based on the flow regime

• Use the Darcy-Weisbach equation to calculate the pressure drop
