ABSTRACT:
In crystallization units such as wax crystallization units where a scraped surface double pipe heat exchanger type chiller is used, the improvement of replacing the scraped surface chiller tube with a porous tube to provide positive flow of coolant through the tube wall to prevent crystal deposition on the process side of the tube, whereby crystal degradation is eliminated and increased filter rate is obtained.
