<p>SELECTIVE CONDENSATION PROCESS AND CONDENSER APPARATUS Contaminant substances having high biochemical oxygen demand, foul odors, etc., are often carried by vapors to be condensed in industrial processes. Certain of these contaminants are more volatile than the primary constituent of the vapor to be condensed. The invention concerns a process and apparatus for separating most of the more volatile contaminants so that separate streams of condensate are produced, one of which is relatively clean while the other stream, though considerably smaller in volume, carries most of the contaminants. A plate type surface condenser having a barrier on the condensing side which prevents the passage of contaminants into a stream of relatively clean condensate is disclosed. In case several different streams of condensate are to be separated, the condenser apparatus has several sections arranged in series.</p> |
