| Abstract: | The tional method of the precooling operation of propylene jar at low temperature was studied in detail and the raprecooling operation was advanced. The results show that the propylene jar could maintain to decrease by one degree in temperature per hour and any two points difference in temperature was less than ten degrees. All of these measures made the propylene jar at low temperature not be deformed. |

| Keywords: | propylene jar at low temperature precooling temperature decrease temperature difference |
