Fractional Condensation

fractional condensation

[¦frak·shən·əl ‚kän·den′sā·shən] (chemistry) Separation of components of vaporized liquid mixtures by condensing the vapors in stages (partial condensation); highest-boiling-point components condense in the first condenser stage, allowing the remainder of the vapor to pass on to subsequent condenser stages.

Fractional Condensation

 

the process of cooling a gaseous or vapor mixture in stages, accompanied by the successive condensation of individual components or their fractions. In industry, fractional condensation is used primarily for the low-temperature separation of gaseous mixtures and for the production of fractions enriched with individual components. The final temperature of cooling of the gaseous mixture in each stage is determined by the requirements for the composition of the condensate.
