A process to prevent fouling using a desublimating heat exchanger is disclosed. An outlet stream from the desublimating heat exchanger may be split into a plurality of parallel streams. The parallel streams may be sent through a plurality of discrete unit operations, and the unit operations may change the temperature of at least one of the parallel streams. Parallel streams of differing temperature may emerge from the unit operations. The parallel streams which are of a similar temperature may be mixed to form a warm stream and a cool stream. The warm stream and the cool stream may be sent to a mixing chamber. A mixed stream of substantially uniform temperature may emerge from the mixing chamber, and the mixed stream may be recycled back to the desublimating heat exchanger. The mixing chamber may be separate from the desublimating heat exchanger, or the parallel streams of differing temperature may be mixed in the desublimating heat exchanger.
