CONDENSER FOR BINARY/POLYNARY CONDENSATION

摘要

A dephlegmation condenser for binary/polynary condensation of a vapor mixture is arranged upright. It has tubes (4) through which the coolant flows, an inlet connection (1) arranged in the top region of the coolant tubes and intended for the mixture to be condensed, and a collecting space (2) arranged below the coolant tubes (4) and intended for the condensate to be drawn off. The inlet connection (1) and the collecting space (2) are connected to one another via a condenser shell (3) encasing the tubes (4). The coolant is directed in pure counterflow to the mixture in the predominant part of the condensation space. The vapor-side, smooth temperature profile achieved is a consequence of the segregation during the condensation. A mixture which is enriched with the higher-boiling component of the mixture condenses at the start of the condensation section, whereas another mixture which is enriched with the lower-boiling component of the mixture condenses out at the end of the condensation section.
