Abstract:
A heat exchange method and apparatus having a cooled fluid flowing in contact with a first surface of a heat exchange wall and a cooling fluid flowing in contact with a second surface of the wall. At least one temperature sensor is located to directly monitor the temperature of the first surface. Flow of the cooling fluid is throttled when the temperature of the first surface drops at least 50 degrees below the freezing temperature of the cooled fluid.
