摘　　要：对低温丙烯罐的预冷工艺进行了较为仔细深入的研究,提出了较为科学、合理的预冷操作方法,确保了丙烯贮罐内罐基本维持每小时温降1℃。罐内任意两点温差不超过10℃的操作条件,对刚刚维修之后的低温丙烯贮罐起到了保障作用。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.
