摘要
介绍了大型国产化二氧化碳汽提法尿素装置的系统配置和工艺特点,总结了其设计中存在的问题和开车后采取的改进措施。实际运行情况表明,大型国产化二氧化碳汽提法尿素装置操作运行稳定,各项指标达到设计要求,吨尿素氨耗和蒸汽耗分别为569 kg和870 kg,尿素产品一等品率达到100%。
The system configuration and process features of large scale domestic carbon dioxide stripping process urea plant are introduced, and problems in design and countermeasures taken after restart up are summed-up. Actual operation situation shows that the operation of the large scale domestic carbon dioxide stripping process urea plant is stable, all indices reach the design requirements, ammonia consumption and steam consumption per ton of urea are 569 kg and 870 kg, respectively, first- rate urea product reaches 100%.
