Abstract

A dephlegmator is provided comprising two stages connected in series wherein a first stage includes an air-cooled reflux condenser and a second stage includes a generally horizontal tube bundle of smooth or finned tubes that can be operated selectively in either an air-cooled (dry) mode under selected ambient conditions or in a wet evaporatively cooled mode under other selected ambient conditions including that of elevated ambient temperature. Spray nozzles may be installed above the tube bundle whereby water can be sprayed onto the tube bundle. One or more collection troughs are preferably provided beneath the tube bundle for collecting run-off water and enabling recycling of excess deluge water. Preferably, the tube bundle comprises at least two, and preferably three groups of tubes communicating with each other wherein the second group of tubes has appreciably fewer tubes in it than the first group of tubes and any third group of tubes has appreciably fewer tubes in it than the second group of tubes.
