Abstract

The technique of removing impurities from low-temperature process streams by freeze-out in heat exchangers is not new. However, published work indicating design criteria for this mode of impurity removal is practically nonexistent. The work discussed in the following sections provides one avenue of approach to the problem of predicting pressure-drop time histories of process heat exchangers in which frozen solids are accumulating. The study derives its original impetus from the need to establish a suitable cycling period for a reversing heat exchanger in which nitrogen is frozen out of a hydrogen stream (i.e., it is desirable to predict the magnitude of pres sure-drop build up as frozen impurity is deposited. The duration of the reversing cycle then depends upon that increased pressure drop with which the system can still economically operate.)
