摘要
文中分析了某石化公司的氮气平衡供应需求和空分装置的生产现状。阐述了将空分装置的产品和氮气工艺流程优化改造方案,并讨论了与液氮储存系统联网应用的外供方案。通过采取合理的开机模式以及改造阀门管线控制、优化操作等措施,提高了氮气总供气能力,取得了较好的经济效益。
This paper analyzed the nitrogen balance supply demand and production status of air separation plant of a petrochemical company,expounded nitrogen process optimization and modification plan, and discussed external supply scheme of interconnection application with liquid storage system. By adoption of measures such as reasonable starting-up mode and modifying valve pipeline control and operation optimization, the total nitrogen supply capacity was increased, and good economical benefit was obtained.
