Abstract
Abstract Disclosed herein is a heat exchanger for altering the temperature of process streams by the use of a plurality of tube bundles made of organic polymeric material disposed within at least one tank having process stream inlet and outlet means. The end portions of the tube bundles are operatively connected to feed and discharge means forming a passageway for circulation of a second liquid through the tube bundles. The tube bundles extend the entire length of the tank and in combination with flow distribution means form an uninterrupted heat exchange region through which only process liquid passing through the heat exchange region leaves the tank.
